Embodiment Construction

[0052] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0053] In order to solve the low calculation efficiency and accuracy caused by relying on experience to manually calculate the slab specifications and weight, it is easy to cause the estimated slabs to fail to meet the order requirements, resulting in a backlog of inventory, or forcing the order to be cut or transferred in the downstream process. Spot sales and other issues. In an optional embodiment, the inventor, such as figure 1 As shown, a process design method for plate rolling that obtains relevant parameters through programming in the production and sales system and accurately calculates the specifications and weight of slabs according to the order information is proposed, which c...

Abstract

The invention discloses a process design method for plate rolling. The process design method comprises the steps that a production and marketing system obtains order information of plates and production capacity parameters of a plate production unit, wherein the order information comprises a plate variety and an ordering width, and the production capacity parameters comprise a plate specificationdesign capability and a plate weight design capability; a plate specification control parameter corresponding to the order information is determined according to the plate variety and the ordering width; a plate blank target width range and a plate blank rated target width of the plate are determined according to the ordering width and the plate specification control parameters; a target weight range of the plate blank is determined according to the target width range of the plate blank; a plate blank target length range and a plate blank rated target length are determined according to the plate blank target weight range and the plate blank target width range; and the manufacturing execution system controls the production and manufacturing of the plate according to the parameters. According to the method, the plate blank specification and weight calculation efficiency and accuracy can be improved at the same time.

Description

technical field [0001] The present application relates to the technical field of plate rolling, in particular to a process design method for plate rolling. Background technique [0002] At present, in the rolling production of plate and strip, such as the rolling production of steel plates, customers will clearly require the type, specification and unit weight of the product in the order, and the current order requirements of customers are becoming more and more diverse. Although in the plate rolling process, the cold rolling unit can perform coil splitting and trimming according to customer requirements, but in the process of continuous casting to produce slabs, the specifications and weight of the raw material slabs cannot be changed flexibly due to the production capacity. Frequent changes in billet specifications and weight not only seriously affect the production rhythm of continuous casting and hot rolling, but also bring defects to product quality. Therefore, during ...
