Method for setting process parameters of stainless steel strip steel withdrawal and straightening machine unit

Abstract

The invention relates to a method for setting process parameters of a stainless steel strip steel withdrawal and straightening machine unit. The method is characterized in that a set of systemic method for setting the process parameters of a stainless steel withdrawal and straightening machine is established by utilizing finite element software to establish a simulation model and applying the stepwise regression principle to set the process parameters such as insertion depths and tension values of a 1# roller, a 2# roller and a 3# roller of a withdrawal and straightening machine, and optimization is achieved by combining application effects of actual production. By means of the method, defects of a wave plate shape and a warping plate shape easily occurring in the production of thinner stainless steel strip steel are eliminated well, theoretical guidance and technical support are provided for withdrawal and straightening of stainless steel, and quality of strip steel is greatly improved. Besides, a process parameter query and addition system interface has strong visuality so that the production is scientific and systematic, and the problem that the process parameters of work shifts are different due to personal experience factors of operators is solved. An adding system guarantees that technical personnel can add process parameters capable of enabling strip steel to obtain good plate shapes after a series of statistics according to actual conditions, so that a database can be kept updated frequently, and process parameter setting can be improved and optimized continuously. Therefore, the method for setting the process parameters of the stainless steel strip steel withdrawal and straightening machine unit has a wide application prospect.

Description

technical field [0001] The invention relates to the correction of cold-rolled plate shape after cold-rolling of stainless steel strips, and more specifically refers to a method for setting process parameters of a tension leveler unit used for correction of thin stainless steel strips. Background technique [0002] In the last process of continuous processing of stainless steel strip, a tension leveler is often installed to improve the quality of the strip, such as Image 6 Shown schematically is the schematic diagram of the stainless steel strip tension leveling machine unit involved in the present invention, wherein the first section frame is composed of a pair of bending roll systems, consisting of 1 and 4 sets of bending rolls in the figure, and the 2nd and 3rd The section frame consists of two sets of leveling rollers distributed up and down: [0003] 1) The first roll system 1 (the lower pressure roll is called 1# roll) and the fourth roll system 4 are used as the first...

AI Technical Summary

Problems solved by technology

In the actual on-site production, I have some understanding of the above characteristics, and adopt some qualitative process parameter formulation methods, but they are all empirical data, and lack necessary theoretical and technical guidance for important production process parameters such as tension and work roll reduction. There is a lack of precise control means and effective measurement methods for strip elongation, so that there is no targeted solution to the shape problems of different incoming materials or other problems, which to a certain extent affects the production quality of strip steel. affected

Through investigation, it is found that in the tension leveling production of thin materials, there are generally wave and warpage defects in the plate shape, and some plate shapes cannot even meet the factory requirements.
