    The invention relates to the field of metallurgy, to devices for the continuous casting of cast iron pipes. The purpose of the invention is to expand the technological capabilities of the device by obtaining pipes with couplings and improving the quality of their surface. The upwardly casting device contains a siphon gating system of refractory material, a water-cooled mold installed on it, and a pipe sleeve forming unit consisting of a steel sleeve and a refractory porous rod), which are made with coaxial expansion upwards. The flange of the rod has an annular groove connected to the air suction system. The proposed device allows to obtain a high-quality surface of the pipe, as well as a strong adhesion between the cast-iron pipe and its coupling. 3 hp f-ly, 4 ill. WITH

    The invention relates to metallurgy, and more specifically to the continuous casting of cast iron pipes with couplings about
    The purpose of the invention is to expand the technological capabilities of the device by obtaining pipes with couplings and improving the quality of their surface.
    FIG. 2 shows a device for continuous vertical casting of pipes, a longitudinal section in FIG. 2 is a part of the device, a longitudinal section, the stage of casting a pipe coupling; FIG. 3 is the same, the stage of solidification of the pipe coupling, FIG. 4 - the device, the stage of drawing out the pipe with the coupling about
    The device for vertical continuous casting of cast-iron pipes contains a siphon gating system 1 made of refractory material, for example, of the silico-alumina type, which has a horizontal sprue channel 2 with a vertical section 3 and a second vertical section 4 with a funnel 5 made height equal to the height of the crystallizer 6 Exit section 7 gating system 1 is made in the form of a truncated cone. The mold 6 is equipped with a water-cooled jacket 8, for example, from copper with a supply of water through channel 9 and its withdrawal through channel Yu D D isolating between the water-cooled jacket 8 and the gating system 1, there is a refractory ring gasket. The device comprises an assembly for forming a sleeve consisting of a steel sleeve 12 made upwardly and with a groove 13 and a refractory porous rod 14 having a cylindrical section 15 in the lower part the shape and installed with a gap 16 relative to the steel sleeve 12, the value of which corresponds to the thickness of the pipe being produced. The rod 14 has a heat-resistant breathable coating 17, made in the form of steel The core 14 is inserted into the steel sleeve 12 by means of a flange 18, in which an annular groove 19 is made, connected through 7 pipe 20 and a shutter 21 to an air suction system. The means for extracting the pipe is made in the form of an annular metal plate 22 rigidly connected to lifting rod 23 suspended from a vertical lifting mechanism (not shown) Liquid iron is supplied in the direction of arrow 24o

    The device works as follows.
    Liquid iron is fed to the mold 6 through a siphon gating system 1 to reach the N level with the valve 21 closed. The cylindrical part 15 of the rod 14 is immersed in liquid iron, then the valve 21 is removed and the air from the annular gap 16 is sucked through the porous rod 14 and the ring groove 19 The molten iron fills the annular gap 16 and as a result of its solidification a sleeve of the cast pipe is formed. Next, liquid iron is added to the mold 6 until the level N is reduced, close the valve 21 and periodically remove the pipe. Up with a permanent level of iron casting in the mold 6. When the cast pipe of a given length reaches, liquid iron from the mold 6 is produced
    On the installation, thin-walled cast-iron pipes with a thickness of 4 mm are obtained for a diameter of 80 mm and a thickness of 7 mm for a diameter of 300 mm
    Due to the complete filling of the annular gap 16 with cast iron, cast iron blanks without shells, gas or air bubbles are obtained by sucking it. Due to the constant supply of fresh cast iron through the gating system 1, the pipe body is cast without impurities, as the slags are trapped on the surface of the cast iron in the funnel 5, By periodically stretching the pipe with uniform stops, uniform cooling conditions are provided, the coupling between the coupling and the pipe is strong, and the surface quality is not good.
