    BACKGROUND OF THE INVENTION The invention relates to a method and an arrangement for the production of stable wire mesh according to the preambles of the appended independent claims. The invention also relates to the use of a product produced by the process on rocks in mine tunnels and similar constructions.
    Background of the Invention On rocks of mining tunnels and similar structures a net is fastened which is made of steel, a so-called mined, to strengthen the tunnel construction and to prevent landslides from loose stones. The mining seam used must be the cracks of the -160 tunnel, for which reason the mining seam must be made of suitable soft wood. On the stable line used for the production of the net, however, there are certain half-strength requirements, depending on the area of use, in order for the net construction produced by it to remain in the area of use. The produced mine should, however, be relatively easily formed so that it can be aged by mechanical pressing to the shape of the tunnel's rock.
    Typically, wire mesh mined from wire mesh means that wire mesh son is healed from steel and with a given diameter is first led to a cold working step, in which the wire mesh diameter is substantially reduced to the desired wire diameter used in the final night construction. The diameter of the rolling bar is typically reduced by 8-30%. The cold processing can be carried out either by rolling or by cold drawing. The cold working requires one or more successive rollers or drawing discs with openings in different sizes, since the diameter of the wire can not be reduced more than a certain part at once. The cold working strengthens the wire, which is why the steel wire must be heat-treated after the cold working in order to achieve the desired accuracy and formability so that the wire can be used for the production of mines.
    The heat treatment consumes considerable amounts of energy and thus increases the production costs of the wet son produced by staltrad. After the warning treatment, the glazed steel line is razed and cut to a desired length, after which a desired night construction is produced by the line by welding.
    SUMMARY AND DESCRIPTION OF THE INVENTION The object of the present invention is to present a method and an arrangement for producing a stable wire bed, preferably a mined one, of rolled wire, which is simpler and thus more cost-effective than a conventional manufacturing method.
    In order to achieve this spirit, the method and arrangement according to the invention are mainly characterized by what is stated in the characterizing part of the independent claims.
    In the other, dependent claims, some formable embodiments of the invention are stated.
    In a typical process according to the invention for producing a steel wire rod, preferably a gruynate, of wire rod - led wire wire of a given diameter to a further processing step, the treated wire rod is unloaded and cut into parts of the desired length, a welded wire is welded by the cut the wire parts, and in which process the average diameter of the roll is not substantially changed in the further processing step, and that the process is free of heat treatment step.
    A typical arrangement according to the invention for dismantling a steel wire mesh, preferably a mined wire, of wire mesh, which arrangement comprises at least - means for guiding a wire mesh to a further processing step, means for further processing the wire mesh, means for raffling the treated wire mesh and for cutting in parts of desired length, and means for welding a seam of wire parts.
    The arrangement is free of heat treatment means, and the means for further processing the rolling line are arranged so that the average diameter of the rolling line does not change substantially in the further processing step. A steel wire mesh made by the method of the invention is typically used in rock tunnels or similar structures to reinforce the tunnel structure and to prevent loose rock from falling. Thus, the nut prepared by the process according to the invention is typically used as a so-called gruvnat. The mine net is typically a flat and flexible steel that can be fastened to the cradle by a mining tunnel or similar construction, and after the fastening of the net, the cradle's cradles can be concrete coated.
    It has now surprisingly been discovered that a mined or a corresponding night structure with a sufficient half-strength and formability can be easily and simply produced from rolled wire of a given diameter, which wire meets the desired requirements for half-strength and formability without a separate heat treatment step. In the production of a steel wire mesh according to the invention, the wire wire used as raw material is guided only by a single further processing step and a rattling step for the formation of the actual wire structure by welding. In other words, in the process according to the invention, the rolling wire is typically led directly than the further processing step to the rating step, possibly by intermediate spinning but without any intermediate steps which would affect the semi-solid properties of the wire. Thus, the manufacturing process according to the invention, which is free from the heat treatment step of the rolling mill, is much simpler and more cost-effective than the manufacturing process according to the prior art.
    In the method according to the invention, the further processing step comprises only a so-called calibration pull, the purpose of which is not to substantially change the average diameter of the rolling bar but the average diameter of the rolling bar Or essentially the same before and after the further processing step. In other words, the average diameter of the rolling bar is kept substantially constant during the further processing step. The average diameter of the rolling row means the mean value of diameters measured at several places in & Aden. At least the diameter of the food in three different places, preferably in at least four different places, for calculating the average diurnal. The further treatment is, however, carried out to remove from the surface of the steel roll line, which is used as a material for the welded shell and other possible slag and contaminants which defend the welding of a seam from the steel line. At the same time, the diameter of the wire can be machined rounder, since the cross-section of an unworked 4 rolled wire is typically not completely round but can be oval-shaped or otherwise deformed.
    In a preferred embodiment of the invention, the average diameter of the rolling bar in the further processing step typically decreases by a maximum of 2 (:) / 0 and more typically by a maximum of 1.5% in relation to the average diameter of the rolling bar before the further processing step. In one embodiment, the change in the average diameter of the rolling bar in the further processing step is typically between 0 and 2%, more typically between 0 and 1.5%, even more typically between 0.01 and 1.5%.
    In a method according to the invention, the further processing is carried out, i.e. the calibration drawing by guiding the rolling wire through at least one drawing disc, the diameter of the opening in the drawing disc being substantially the same as the average diameter of the rolling thread. In a preferred embodiment, the roll wire is guided through only one draw plate, the process being as simple as possible. Alternatively, the further processing can be carried out in the method according to the invention by guiding the rolling row through one or more rolling units in such a way that the average diameter of the rolling row does not change substantially. In a preferred embodiment, the rolling line in the further processing step is guided by only one rolling unit so that the average diameter of the rolling line does not change significantly.
    Since the purpose of the calibration drawing step is only to remove filaments from the surface of the wire rod used as the raw material for the wire rod, the production speed in this step can be kept high. In one embodiment of the invention, the production speed, which means that the running speed of the rolling bar in the further processing step is essentially the same as the maximum speed of the reel unit used in the further processing. The production speed is, for example, about m / s. The production speed is thus not affected by the fact that the rolling line is guided by further processing means, such as a traction sheave or a pair of rollers.
    The rolling mill used in the process according to the invention is a wire which is made of steel by hot rolling and which typically has a circular cross section. The gross bending (Aio) of the roll bar used in the process according to the invention is typically about 25-35 ° A. The fracture toughness Rn, of the rolling bar is typically about 370-420 N / mm2 and the tensile strength RP0.20 about 320-370 N / mm2.
    A typical steel wire bar, preferably a mine wire according to the invention, is essentially made of smooth steel wire, i.e. further processed wire wire.
    In a preferred embodiment of the invention, rolled wire is used as the material for the mining seam, the diameter of which is about 5.5 mm or 6 mm. Since the method according to the invention does not substantially affect the diameter of the wire, the steel wire seam according to the invention is thus made of steel wire with a diameter of about 5.5 mm or 6 mm. The diameter of the thread affects the mesh width of the net being produced, in order to achieve the desired half-strength and weight of the net. The diameter of the thread and the mesh width of the net produced by it are selected according to the area of use.
    Of cut parts of treated wire mesh, ie. stable wire, a wet-shaped structure is formed, and the wire parts which in the construction are placed on top of each other are welded to each other in the stable where the parts cross each other.
    DETAILED DESCRIPTION OF THE INVENTION In the following, the invention is described in more detail with reference to the accompanying Figure 1, which illustrates the method and arrangement according to the invention.
    In the method according to Figure 1, wire rod 2 used as a starting material for a structure 1 is led to a further processing step 10, in which the wire rod 2 is led through either at least one draw plate or a rolling unit so that scale can be removed from the surface of the wire rod. After the further processing step 10, the treated rolling bar 3 can be rewound before the treated rolling bar 3, i.e. the steel bar is passed on to a subsequent step 20, in which the steel bar 3 is routed and cut into parts 4, 4 'of desired length. The straightening of the trade means the direction of the trade, so that it will be possible to cut off substantially straight elongated parts 4, 4 'of the trade.
    From the parts 4, 4 'cut off by the steel row 3, a wet-shaped construction 1 is formed, preferably a mined, thoroughly welded one. The night structure 1 is welded 6 at the intersection of the parts 4, 4 ', where the parts 4, 4' which are placed in different directions relative to each other lie on top of each other.
    The following is an example of a mine prepared by a process according to the invention.
    Example For the production of a Nat'and rolling mill made of steel whose - average diameter is 5.5 mm - elongation at break A10 = 25-35% - fracture toughness Rm = 370-420 NI / mnn2 _ yield strength RP0,20 = 320-3701 l / mm2 The rolling wire is drawn through a drawing disc, the opening of which has a diameter of 5.5 mm, or through a rolling unit which is installed at 5.5 mm in diameter in order to be able to clean the scale away from the surface of the rolling wire (so-called calibration drawing). The average diameter of treated wire rod is at most 1, (:) / 0 smaller than of untreated wire rod.
    After the calibration run, the treated smooth stable line is razed and cut into parts of the desired length. A wet-shaped construction of the desired size is welded to the cut-off parts. For example, the size of the steel wire mesh is 2270 mm x 2530 mm and the nose width of the mesh is 75 mm x 75 mm, thereby achieving the desired hall strength and formability properties of the mesh.
    The invention is not to be limited to the embodiments presented as examples above, but the invention is to be applied in a broad way within the scope of the invention as defined in the following claims. 7
