Dynamic slab cutting design method and system

Abstract

The invention provides a dynamic slab cutting design method and system. The method comprises the following steps that: production order information sent by an ERP system is received, and an original cutting plan is generated according to the production order information; a converter actual performance information dynamic condition sent by a secondary continuous casting system is received, and slabcutting plan information is generated according to the original cutting plan and the converter actual performance information dynamic condition; and the slab cutting plan information is sent to the secondary continuous casting system, so that the secondary continuous casting system executes the slab cutting plan information; and slab cutting actual performance information sent by the secondary continuous casting system is received. With the dynamic slab cutting design method and system of the invention adopted, binding relationships between original heat slab cutting plans and heat numbers are broken; great inconvenience brought to plan execution caused by the instability of heat steel tapping can be eliminated; an execution plan with plan numbers adopted as units is formed; production organization level can be improved; and residual slab cutting loss can be decreased.

Description

technical field [0001] The invention relates to the technical field of steelmaking information, in particular to a dynamic slab cutting design method and system. Background technique [0002] At present, the secondary system of continuous casting in steelmaking plants generally executes the slab cutting plan in units of heats. Due to the instability of the tapping amount of the converter, when the actual amount of molten steel in a furnace is less than the planned amount of molten steel, the planned slab will not be produced. In order to meet the needs of the order, the production must be scheduled again, which will bring great impact to the planning and production organization. There are many problems; when the actual amount of molten steel in a furnace is greater than the planned amount of molten steel, it will lead to the output of unplanned blanks, which will increase related costs such as inventory, transportation and cutting.

Due to the instability of the tapping amount of the converter, when the actual amount of molten steel in a furnace is less than the planned amount of molten steel, the planned slab will not be produced. In order to meet the needs of the order, the production must be scheduled again, which will bring great impact to the planning and production organization. There are many problems; when the actual amount of molten steel in a furnace is greater than the planned amount of molten steel, it will lead to the output of unplanned blanks, which will increase related costs such as inventory, transportation and cutting
