    专利说明:

    Invention kaachech; melting the apparatus for converting the melt blend into semi-finished products obtained by continuous casting, starting directly from the metal charge, without any downtime in the installation, it is possible to make tags, blooms, bars, bars and ingots by means of continuous and or periodic batch processes, in particular, the invention is successfully applied dp continuous casting method
    The purpose of the invention is to increase productivity and reduce energy consumption.
    The drawing shows an installation for the continuous production of steel, top view
    The installation consists of a feeder 1. a supply pipe 2 of a collector 1 for collecting gases and smoke, a chamber 4 for preheating a charge made in the form of a rotating drum. A burner 5 is installed inside the chamber, and at the end of the chamber there is an end feeder 6 The mixture is loaded into an electric furnace 7, which is powered by a transformer 8 or an electrical circuit. The metal is released into a ladle 9, which is transported with a multifunctional manipulator 10 Exhaust gases are removed through conduit 11 into filters 12, further sucked by a fan 13 and left into a chimney 14 A heat regenerator 15 is connected between the filters and the fan. A heat regenerator is also used to preheat the air used in the burned 5, and this air can be supplied by another fan 16.
    The installation works as follows.
    The metal charge is continuously poured from the feeder 1 through the supply pipe 2 to the preheating chamber 4, which contains a collector 3 at the outlet end for collecting gases and smoke. The preheating chamber 4 is a rotating drum which allows the metal charge to be uniformly heated.
    A heating medium, such as gases and smoke, which are produced by the burner 5 operating inside the preheating chamber 4 and adjacent to the end feeder 6, passes through the preheating chamber 4 in the opposite direction to the metal charge,
    The final temperature of the preheated metal charge may vary between 300 and 75 ° C by
    adjusting the flow of the heating medium and the heating energy respectively.
    To eliminate the adverse effects on the metal charge in the chamber
    4 preheats maintain a controlled atmosphere.
    Pre-heated metal charge is loaded continuously into the electric furnace 7 through the final feeder 5.
    0 The flow of the metal charge through the feeder 6 is continuously adjusted by means of an appropriate regulator to maintain the desired tempoise in the metal bath.
    5 The electric furnace 7 is powered by a transformer 8 or an electrical circuit. The discharge of the heat from the electric furnace 7 is performed through certain interpals, and in the meantime, the output of the melting is reduced to approximately thirty minutes by the proposed invention.
    The melt production time is reduced to about 2 minutes, and the melting output is such that the supply of liquid metal in the electric furnace 7 remains, the amount of which can even be 40% of the nominal capacity of the furnace.
    The released metal is collected in a non-9 trustable multifunctional manipulator 110 installed between the posed points of metal release 17 from the furnace and casting 18, and which moves and installs bucket 9 on
    5 different positions needed to carry out all the casting functions and also the return functions of the bucket itself.
    The manipulator 10 has dia independent arms, 19 and 20 which can rotate around the circumference and move in the vertical direction to transfer the two buckets alternately and simultaneously.
    The multifunctional manipulator 10 has a smelting discharge position 17, interoperating with an electric furnace 7, a refining position 21 of metalsg / for heating a liquid bath and possible degassing), a slag formation position and a casting position 8 along with an intermediate
    0 capacity. Thus, achieving continuous casting is possible in a very short amount of time required to replace the bucket 9.
    In addition, multi-functional
    5, the manipulator 10 conveys to the position 9 for the release of slag and for washing the ladle to the position for heating the ladle and also to the position for returning the mold cover. The various positions are about 45 and 90 ° to each other, and two buckets
    can be installed with the possibility of reciprocating motion at a right angle to the axis of rotation of the multipurpose manipulator 10.
    At the casting position, the multipurpose manipulator 10 allows the bucket 9 to deliver its contents to the intermediate casting device at the casting position 18, and thanks to the multipurpose manipulator 10, the casting position 18 is continuously maintained because even when the liquid metal content in the intermediate casting device is at minimum, - it is enough to cover the transition state when replacing the bucket 9
    The casting position 18 consists predominantly of an intermediate casting device serving the continuous casting plant, but it can include a zone for casting in a mold, or a combined multifunctional zone.
    The exhaust gases leaving the collector 3 and passing through the preheating chamber 4 in the opposite direction to the metal charge are removed through conduit 11, which is transferred; them to the filters 12, from where they are sucked in by the fan 13 which pulls them into the so-called new pipe 14.
    The heat regenerator 15 is connected between the filters 12 and the fan 13 and it can
    interact with the whole gaseous mass of filters 12 or only with its part. The heat regenerator 15 is also used to preheat the air used in the burner 5, and this air can be supplied by another valve
    LRTOR 16.
    The use of the installation allows to achieve the minimum specific consumption of energy, MI and pgm-south specific consumption of electrodes;
    By installation, for installation of continuous; 11 articles including chambers for heating metalic i / ih with chambers, l and the final feeder, an electric furnace and a transformer that is different in order to increase performance and reduce consumption OHS is equipped with a multifunctional manipulator installed between the metal release from the furnace and the casting station and having two independent levers that can be rotated around the circumference and moved vertically, and between the gozins release And | - chel- to. located position ram.gfo anik
