A device and method for simulating twin-roll strip continuous casting process

Abstract

The invention discloses a device and method for simulating a twin-roll strip continuous casting process, comprising a smelting system for melting metal, a cooling base assembly located above the smelting system, and controlling the lifting of the cooling base assembly to be inserted into the smelting system to melt metal The lifting mechanism and the cooling system for cooling the surface of the cooling base assembly, the cooling base assembly includes a pair of cooling bases arranged parallel and side by side, and there is a gap between the pair of cooling bases for simulating the roll gap of the thin strip continuous casting crystallization roll, There is a temperature-measuring thermocouple in the gap, and it also includes a hot-rolling system that drives a pair of cooling substrates to move toward each other and an elastic reset member connected between the pair of cooling substrates. There is a cooling flow channel in the cooling substrate, and the temperature-measuring thermocouple and The cooling system is connected with the temperature acquisition system. The device can simulate the twin-roll extrusion process and the on-line hot rolling process of the strip, which has important guiding significance for improving the surface quality and mechanical properties of the steel strip.

Description

technical field [0001] The invention belongs to the technical field of iron and steel casting, and in particular relates to a device and method for simulating a twin-roll strip continuous casting process. Background technique [0002] Strip continuous casting includes single strip continuous casting, double strip continuous casting, single roll thin strip casting and twin roll thin strip continuous casting. Among them, the twin-roll strip continuous casting technology is considered to be the most revolutionary cutting-edge technology in the field of iron and steel metallurgy in the 21st century. In the process of twin-roll thin strip casting and rolling, the molten steel is cast directly on the water-cooled copper crystallization roll into a thin steel strip with a thickness of about 1-5 mm, which produces a sub-rapid solidification effect and saves the need for traditional continuous casting. Reheating and a large number of rolling processes, thus realizing the integrated ...

AI Technical Summary

Problems solved by technology

However, the closed water-cooled matrix structure around the inner cavity of the device makes it difficult to control the roughness of the matrix surface, and at the same time, it is difficult to adjust the thickness of the strip obtained at any time, and it cannot simulate the online hot rolling process of the strip.
