Embodiment Construction

[0037] The invention provides a device and method for optimizing the casting billet production plan during the rapid replacement of the tundish. By optimizing the production plan and reducing the generation of waste billets, it is suitable for the adjustment and optimization control of the production plan during various rapid replacement of the tundish, and improves the metal Yield rate, reduce production cost.

[0038] In order to clearly illustrate the technical characteristics of the method, the following describes the solution through a specific implementation mode:

[0039]After the data communication unit collects the on-site basic automation equipment event "quick replacement of tundish", it triggers the production plan optimization calculation unit to optimize the length of the uncut slab during the replacement of the tundish and in the previous furnace. The specific steps are:

[0040] Step 1. The data communication unit reads the length of 35.8 from the head of the u...

Abstract

An optimization device and method for a casting blank production plan during a period of rapidly exchanging a tundish belongs to the field of automatic control of continuous casting. The length of an intermediate blank is adjusted into the sum of the length of a fixed size blank length, a blank head setting length and a blank tail setting length through optimizing the casting blank production plan before a joint point is optimized; when the optimization device is used for linearly cutting, only the blank head setting length and the blank tail setting length are cut off, and a residual casting blank is still a casting blank product without quality problems. The device is composed of industrial equipment and a software processing unit; the industrial equipment comprises a server and an industrial computer; the software processing unit comprises a data communication unit, a data storage unit, a production plan optimization calculation unit and a client. The optimization device and method have the advantages that waste blanks are reduced with regard to cutting optimization treatment of the tundish produced during the period of rapidly exchanging the tundish, the yield of liquid steel is improved and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of automatic control of continuous casting, and in particular relates to a device and method for optimizing a billet production plan during rapid replacement of a tundish. Background technique [0002] The general production process of quick replacement of tundish refers to that with the reduction of the previous molten steel in the old tundish, the casting speed is gradually reduced from the normal casting speed. When the stopper rod closes the pulling speed, select the quick change tundish mode at the same time. The tundish worker stops the baking of the new tundish and drives the tundish truck to the side of the old tundish truck. When the stopper rod closing speed is reached, close the stopper rod, drive the old tundish car to the baking position, and drive the new tundish car to the pouring position at the same time. When the weight of the molten steel in the new tundish reaches the pouring weight, pouring is s...
