Abstract

The embodiment of the invention discloses a continuous casting blank sizing method and system. The method includes the steps that the withdrawing speed, controlled through a frequency converter, of withdrawing of a withdrawing and straightening machine is obtained in real time; whether a casting blank in-place signal on an original point position or a limiting position is received or not is judged; when the casting blank in-place signal is received, the withdrawing length of the withdrawing and straightening machine is calculated according to the withdrawing speed; whether the withdrawing length reaches the casting blank sizing length or not is judged; and if the withdrawing length reaches the casting blank sizing length, a cutting machine at the original point position is used for cutting a casting blank. By means of the continuous casting blank sizing method and system, the sizing precision of the casting blank is improved, and meanwhile the maintenance cost of the system is reduced.

Description

Technical field [0001] The invention relates to the technical field of automatic control, and in particular to a method and system for sizing continuous casting slabs. Background technique [0002] The molten steel smelted in the steelmaking plant is continuously cast by the continuous casting machine into a cast slab. After the cast slab is straightened by the tension leveler, it is cut to a certain length by a cutting machine according to the needs of the next process after a fixed length on the roller table. The slab sizing accuracy has a considerable influence on the next process, directly affecting the output and quality of the continuous caster, and directly related to the sizing rate and yield rate of rolled steel. [0003] In the prior art, for a long time, the length of the cast slab has been determined by manual observation or roll measurement. Manual observation of the fixed length is mainly to cut through manual observation and measurement when the cast slab is moving ...
