Embodiment Construction

[0122] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0123] Figure 1-Figure 4 In, the method of the present invention is:

[0124] A load distribution method for hot and cold rolling, which adopts a single-pass back-and-forth hot-rolling rough rolling first, then six-pass hot-rolling finish rolling, and finally two-pass cold-rolling. Under the premise of constrained by factors of equipment and equipment, in the various schemes of hot rolling rough rolling, finishing rolling and cold rolling load distribution, the best load distribution scheme is obtained by using the particle swarm optimization algorithm, and the specific steps are as follows:

[0125] Step 1: Read in the original data, including the steel grade and specification of the raw material, the specification of the finished product, the total rolling passes of hot rolling and cold rolling, the rolling temperature of each stand, the radius of t...

Abstract

The invention relates to a hot / cold rolling load distribution method. The hot and cold rolling load distribution is comprehensively considered on the premise of meeting steel rolling process constraint and equipment constraint, and the aims of improving the product quality and the production efficiency and saving the production energy consumption are fulfilled. Due to a mode of performing at least once hot rough rolling, performing multiple hot finish rolling and performing multiple cold rolling finally, an optimal load distribution scheme is obtained through a particle swarm algorithm in multiple schemes of distributing loads of the hot rough rolling, finish rolling and cold rolling on the premise of meeting the steel rolling process factor constraint and the equipment constraint.

Description

technical field [0001] The invention relates to a hot and cold rolling load distribution method. Background technique [0002] The steel rolling production process is divided into hot rolling and cold rolling, which are produced by hot rolling mills and cold rolling mills respectively, and their production costs are calculated separately. Considering that most of the strip products produced by the hot rolling mill will be used as raw materials for the cold rolling mill, if the thickness of the finished strip steel produced by the hot rolling mill is small, the production cost of the hot rolling mill will be increased; If it is large, it will increase the production cost of the cold rolling plant. From the point of view of energy saving, the separation of cold rolling and hot rolling production processes has caused unbalanced distribution of the entire steel rolling load, increased production energy consumption, and affected product quality. Therefore, it is necessary to co...
