Continuous casting and continuous rolling integration control method

Abstract

The invention provides a continuous casting and continuous rolling integration control method comprising the following steps: ensuring a rolling plan; ensuring a steelmaking plan according to the rolling plan; and executing the steelmaking plan and the rolling plan. The continuous casting and continuous rolling integration control method is especially suitable for uniformly weaving and controlling a steelmaking and steel rolling production plan of an enterprise which is oriented to a production organization mode of an order to produce. Compared with the prior art, the continuous casting and continuous rolling integration control method has plan integration, easy realization, high efficiency and dynamic regulation, realizes the unity and the compatibility of the metallurgy continuous casting and continuous rolling production plan, completely satisfies the requirement of a technical constraint condition and increases the production plan executing rate and the order hanging rate, thereby increasing the product rate and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of continuous casting and rolling integrated control, in particular to an integrated continuous casting and rolling planning preparation and control method. Background technique [0002] The continuous casting and rolling production line realizes the direct connection between steelmaking and steel rolling process: after the molten iron is smelted into molten steel in the converter, it is refined and adjusted. After the molten steel is adjusted, it is poured into the continuous casting machine to form a slab. After cutting, it enters the soaking furnace directly from the roller table, and then enters the rolling mill to be rolled into steel coils. There are only two processing methods for the slabs cut by the casting machine: one is that the slabs are rolled into steel coils through a rolling mill, and the other is that the slabs are cut into waste products. At present, there is no slab stacking warehouse ar...

AI Technical Summary

Problems solved by technology

At present, there is no slab stacking warehouse area for buffering between the casting and rolling processes of the continuous casting and rolling plant. It is a short-process production process. The connection between the upper and lower processes is tight and the impact is great, making the preparation and control of the production plan very difficult. When preparing the plan, it is necessary to consider steelmaking and steel rolling as a whole, and prepare an integrated plan. At the same time, when implementing the plan, it is necessary to control and adjust the integrated plan in real time to meet the actual needs of continuous casting and rolling production.
