The Method of Controlling the Width of Mixed Slab

Abstract

The invention provides a mix-poured plate blank width control method. The method comprises the steps that (1) a steel plate blank making planning system receives a plate blank production schedule and sends the schedule to a steelmaking continuous casting model system; (2) after separately calculating steel component parameters, the steelmaking continuous casting model system sends the steel component parameters to a continuous casting machine for conducting casting; (3) the optimal cutting length is calculated in the casting process and sent to a flame cutting machine for cutting, and meanwhile, a data acquisition system is notified to acquire practical data of cutting; (4) the steelmaking data acquisition system conducts data acquisition on practical situations of casting and cutting and then sends the data to a hot rolling data receiving system; (5) after receiving the data, the hot rolling data receiving system sends the data to hot rolling width models, and control widths corresponding to the models are separately calculated; and (6) a hot rolling database storage system stores three sets of calculation result data of the width models, and sends down set data in real time to a primary PLC system for width equipment control. By adoption of the mix-poured plate blank width control method, abnormal loss of the mix-poured plate blank width can be effectively reduced.

Description

Technical field: [0001] The invention relates to a method for controlling the width of a mixed cast slab, and belongs to the technical field of metallurgical steel production control. Background technique: [0002] At present, mixed-cast slabs at home and abroad are mostly judged as a kind of special treatment slabs. In subsequent production, most of them are produced according to one material or comprehensively judged as another material. In general, they will be produced according to the high strength grade of steel. The material is used for the production organization, and the width control is also controlled according to one material steel type. This causes the actual production process to be difficult when the production is rolled to the transition section and another material steel type. Large fluctuations in the control have seriously affected product quality. Summary of the invention: [0003] The purpose of the present invention is to provide a method for controlling the...

Problems solved by technology

[0002] At present, most of the mixed cast slabs at home and abroad are judged as a specially treated slab. In the subsequent production, most of them are produced according to one material or another material based on comprehensive judgment. Generally, steel grades with high strength grades are used for production. The material is used for production organization, and the corresponding width control is also controlled according to one material steel type. This causes in the actual production process, when the production rolls to the transition section and another material steel type, the width control is difficult, and the width There is a large fluctuation in the control, which seriously affects the product quality
