Control Technology of Width Adjustment In-line for CSP Crystallizer of the Hot Rolling Plate Plant

马钢CSP薄板坯连轧生产线上的连铸机使用漏斗型板式结晶器,其宽度和锥度可在连续浇注过程中不降低拉坯速度的前提下在线连续调节。重点介绍了结晶器在线调宽的原理、方法以及控制系统的组成、结构与功能。

The continuous casters used in the continuous rolling production line for CSP thin plate blank of Maanshan Iron & Steel Co. Ltd. used funnel plate crystallizers. Width and taper of the crystallizer may be continuously adjusted in line under the conditions of continuous casting and that the blank drawing speed was not reduced. The principle and method of width adjustment in-line for the crystallizer were emphasized, and the composition, structure and function of the control system were presented.
