AI Technical Summary

Technical Problem

In the continuous casting process of the steel production process, the cutting length of the tailblank is difficult to accurately control, resulting in low metal yield and inability to meet the requirements of fixed or loose rulers, which in turn affects production efficiency and economic benefits.

Method used

By developing a continuous cast tailblank cutting length optimization model on the casting machine body program, the casting length of the continuous casting bill is determined according to the target requirements of the fixed ruler and the loose ruler, and precise control of the tailblank cutting length is achieved by controlling the converter loading amount.

Benefits of technology

The precise control of the cutting length of continuous cast tail blanks has been achieved, which reduces waste, increases metal yield, and increases economic benefits. The average monthly production of tail blanks can be reduced by 94 tons, with an annual output of 1.081 million yuan.

Abstract

The invention relates to a method for controlling the cutting length of a continuous casting tail billet, which comprises the following steps of: determining the casting length of a continuous casting billet according to the target requirements of fixed size and scattered size, and obtaining the total casting length of the continuous casting billet by adding the casting length of the continuous casting billet, the length of a continuous casting head and a continuous casting tail billet required by a process standard and the shrinkage length of the continuous casting billet before cutting; determining continuous casting steel material consumption and converter steel material consumption according to the total casting length of the continuous casting billet to obtain required molten steel quantity and converter loading quantity; by controlling the charging amount of the converter, the cutting length of the continuous casting tail blank is controlled. According to the method, the continuous casting tail blank cutting length optimization model is developed on a casting machine body program, and accurate control over the tail blank cutting length can be achieved, so that the length of the continuous casting tail blank is shortened, and the tail blank output is reduced.
