Furnace, dispatching method and device for aluminum continuous cast-rolling production

Abstract

The invention relates to a furnace, a dispatching method and a device for aluminum continuous cast-rolling production and belongs to the technical field of aluminum industrial plate processing information. Manufacturing processes are described and constraint conditions are determined by utilizing production process parameters, taking electrolytic tanks and a continuous cast-rolling unit as objects and taking minimization of the electrolytic tanks, purity difference among furnace orders distributed by the electrolytic tanks, purity and position difference among the electrolytic tanks with the same distributed furnace order, manufacturing period and idle production capacity of the furnace orders in the whole plan as objectives, and furnaces and furnace order dispatching of the electrolytic tanks are determined by adopting the scatter search. Established product tasks are completed while production time of an aluminum continuous cast-rolling process is reduced, so that operation efficiency of the machine is improved; operations of furnace cleaning caused by different purities of adjacent furnace orders and halt for adjusting a crystallizer caused by different widths and thicknesses of the adjacent furnace orders are reduced, so that loss of materials can be reduced; and production task planning of the unit is more rational, so that production quality of aluminum coils can be improved.

Description

technical field [0001] The invention belongs to the technical field of plate processing information in the aluminum industry, relates to automation technology, and in particular to a method and device for grouping furnaces and dispatching of aluminum continuous casting and rolling production. Background technique [0002] Continuous casting and rolling of aluminum products refers to the process of direct casting and rolling of aluminum coils with liquid aluminum. During the production process, alumina and other raw materials are electrolyzed into liquid aluminum with high purity in the electrolytic cell, which is transported to the melting furnace through a vacuum bag. The pretreatment operation is carried out in the smelting furnace (adding the necessary alloy raw materials to adjust the chemical composition, after being fully mixed and standing) and then rolled into aluminum coils of certain specifications through the casting and rolling machine, such as figure 1 shown.

Problems solved by technology

This method has the following disadvantages: 1. Due to the large amount of data in the electrolyzer and the contract, the factors to be considered are complicated, and it is difficult for technicians to consider all production information as a whole; 2. It is difficult to consider quality and production efficiency at the same time in the manual operation method and customer satisfaction and other requirements; 3. It involves two processes of electrolysis and continuous casting and rolling. It is difficult to integrate the two stages by manual operation, so it is difficult to obtain a satisfactory production plan by manual operation.
