Abstract

The invention relates to the field of continuous metal casting. The purpose of the invention is to simplify the casting process. For this purpose, from the casting ladle, liquid metal is fed to the receiving funnel 6 of an intermediate device 5, which distributes the metal by free flow over thresholds 8, 9 and 10 through refractory wires 7 to streams 1, 3 and 4 of the mold 2. If necessary, increase or decrease feed metal through any threshold 8, 9 or 10 intermediate device 5 is tilted around the respective axes bb, bb, with the bb axis located in a vertical plane passing through the middle stream 1, and bb axis parallel to horizontal technology eskoy axis machines. 1 il.

Description

one

The invention relates to metallurgy, in particular, to the technique of continuous casting of metals, and is intended to regulate the process of pouring into a mold a three-strand machine with a linear arrangement of streams through the thresholds of an intermediate device located along the apexes of a triangle.

The purpose of the invention is to simplify the casting process.

The drawing shows a diagram of an apparatus for carrying out the proposed method.

The device for continuous casting contains an average stream 1 of the mold 2, extreme streams 3 and 4 of the mold 2, an intermediate pouring device 5 with a receiving head 6 and refractory metal conductors 7 in streams 1, 3 and 4 of the mold 2 and overflow thresholds 8-10 for supplying metal in the middle 1 and extreme 3 and 4 streams. Overflow thresholds 8–10 are located along the triangle abc. The diagram also shows the horizontal technological axis А-А of the three-strand casting machine the axis BB and lying in the vertical section of the bridge passing through the middle stream 1 and the axis B-B of the turn, Serving for the regulation of metal in the middle stream 1, Axis B-B serves to regulate the consumption of metal in streams 3 and 4. The axis B-B is located parallel to the horizontal technological axis A-A of the machine.

The method is carried out as follows.

From the casting ladle (not shown), the liquid metal is fed to the receiving funnel 6 of the intermediate device 5, which distributes the metal with a free overflow through the thresholds 8-10 through the refractory wires 7 to the streams

1, 3 and 4 of the mold 2. If it is necessary to increase or decrease the supply of metal through any of the thresholds 8-10, the intermediate device 5 is tilted around the respective axes BB and B-C. The regulation of the supply of metal to the outer streams 3 and 4 is carried out by turning the device 5 about the axis BB, and in the middle stream, about the axis BB,

Since the regulation of the metal consumption according to the proposed method is carried out by tilting the intermediate device around mutually perpendicular axes, one of which is parallel to the horizontal technological axis of the machine, and the other lies in a vertical plane passing through the middle stream, for this purpose two tilting mechanisms are required. this device and, therefore, a smaller number of staff, which simplifies the process of casting.
