A method for optimizing cutting length of continuous casting tail billet

Abstract

The invention belongs to the field of steelmaking, and particularly relates to a method and device using computer programs to carry out continuous casting tail blank fixed length optimizing cutting. The method using the computer programs to carry out continuous casting tail blank fixed length optimizing cutting includes the following steps that 1, a continuous casting tail blank optimization program on a continuous casting master control displayer is selected and started; 2, after a stopper rod of an intermediate steel ladle is closed, molten steel liquid level data are collected through a liquid level detector; 3, the molten steel liquid level data are sent to the continuous casting master control displayer, and the continuous casting master control displayer calculates the length L4 of an optimizing billet; 4, according to a process control requirement range which is set in advance of residual billets, comparison and optimization with the L4 are carried out by the continuous casting master control displayer to work out a new single-multiple fixed length L of the billets, and the L is sent to the continuous casting master control displayer and a cutting operation displayer to be displayed. According to the method and the device, under the situation that the quantity of molten steel is unequal to integer multiples of a casting blank fixed length, the redundant quantity of molten steel less than the single-multiple fixed length is uniformly distributed to multiple qualified casting blanks ahead of time.

Description

Technical field [0001] The invention belongs to the field of steelmaking, and in particular relates to a method and a device for optimizing and cutting a continuous casting tail billet by using a computer program. Background technique [0002] Continuous casting means that the molten steel flowing down from the tundish is crystallized by the crystallizer into a steel billet and enters the straightening roller table (ie steel channel) of the continuous casting machine and is stretched and straightened into a finished steel billet. Flow (each flow refers to the last billet after the continuous casting of molten steel from the tundish to the steel channel of the continuous casting machine to cast steel) after pouring is stopped, and the flame cutting machine is cut to length. At the end of each casting pass, each stream will produce a tail. Assuming that a 150 billet continuous caster with two machines and two streams (two machines and two streams refers to two continuous casters u...
