Method for controlling molten steel processing of steelmaking workshop

Abstract

The invention relates to a method for controlling molten steel processing of a steelmaking workshop. Process constraints in actual production are taken into account to reduce heat losses of molten steel and obtain a process for controlling the molten steel processing of the steelmaking workshop. By adopting the method, prompt production can be achieved, the times of interruption to casting can bereduced, the rate of utilization of production equipment can be increased, the production of a steelmaking plant can be carried out according to the processing startup time of heat on each machine, and the heat can be promptly delivered to a continuous casting machine to ensure continuous casting. Meanwhile, the load on each refining device is uniform, the failure rate is low, and the productivity of the continuous casting machine and the steelmaking workshop can be improved. By adopting the method, new production schemes can be prepared in a short term according to new production environments so as to deal with unavoidable equipment faults and other unexpected accidents. Due to the reasonable and efficient control of the molten steel processing progress, the heat can be utilized on the reasonable machine, excessive heat delivery can be reduced, energy can be saved, the logistic cost can be decreased, the waiting time of molten steel in different procedures and heat losses of the molten steel can be reduced, and the effects of energy conservation and consumption reduction can be achieved.

Description

technical field [0001] The invention belongs to the technical field of steelmaking production in iron and steel enterprises, and specifically relates to a method for controlling the processing rhythm of molten steel in a steelmaking workshop. Background technique [0002] Iron and steel enterprises are typical process industries. With the increasingly fierce competition in the steel market, the production of steel products presents a trend of multi-variety and small batches. The steelmaking-continuous casting production process is the core process of modern iron and steel enterprises. The control of energy saving and consumption reduction of high-temperature liquid logistics in steelmaking workshops plays a very important role in ensuring the efficient operation of iron and steel enterprises and reducing costs. [0003] The main production processes corresponding to the steelmaking workshop are steelmaking, refining, and continuous casting. The main production equipment incl...
