Steel strip feeding system of continuous casting crystallizer

Abstract

The invention belongs to the field of metallurgy, and particularly relates to a steel strip feeding system of a continuous casting crystallizer. The system comprises a guiding pipe (2), an electromagnetic vibrator (3), an intermediate tank (4) and a crystallizer (7), wherein a steel strip (1) enters the electromagnetic vibrator (3) from the guiding pipe (2), and then enters the crystallizer (7); when the steel strip (1) is fed into the crystallizer (7), the electromagnetic vibrator (3) gives forced resonance to the steel strip (1) by dint of an electromagnetic effect; the guiding pipe (2) adopts an i type; an opening sealing clamp (8) is fixed in a longitudinal opening of the guiding pipe (2); and one end of the clamp (8) can rotate by surrounding a rotating shaft, and the other end of the clamp (8) is connected with a locking piece (11) via a locking notch (10). The steel strip feeding system can quickly exchange steel strips, so that continuous and smooth feeding of the steel strips in a continuous casting process is guaranteed, the vibration energy is prevented from being transferred to an opposite direction to fused masses, the traction is stable, cast metals are cooled evenly, and the feeding quantity of the steel strips is proper.

Description

technical field [0001] The invention belongs to the category of metallurgy, and in particular relates to a continuous casting crystallizer belt feeding system, which can be used for continuous casting slabs, and can also be used for liquid metal alloy smelting and denaturation treatment. Background technique [0002] The mold feeding belt system feeds the elastic steel belt with a certain thickness into the crystallizer, and uses the melting heat absorption of the steel belt in the melt to change the temperature field of the melt in the mold and reduce the superheat and temperature of the melt in the mold. The temperature gradient of the temperature field and the mechanical movement of the steel belt are used to break the dendrite structure of the melt and increase the nucleation points for grain growth. , It can also play a good role in improving the slab segregation, looseness, cracks and other defects that are easy to occur in the continuous casting process.
