Method for designing ASSEL roll profile based on neurotransmission network technique

Abstract

The invention provides a method based on ASSEL roll shape of a technical design of a genetic neutral network and includes the following steps: (1) first, a roll shape design parameter of the ASSEL unit and a comparison table of rolling technique parameter are used for choosing input / output eigenvector and a parameter estimated model of ASSEL roll shape is established through a reasoning estimated method of the genetic neutral network; (2) the rolling technique parameter is collected on line to deduce appropriate production conditions and the roll shape characteristic parameters of different specifications; (3) the intelligent optimization of the estimated model and geometric parameter can be used for getting reasonable design roll parameter, meanwhile, the parameter can be amended manually and dynamically; (4) finally, Auto CAD software output processing parts graph can be passed. The effect of the present invention is that the characteristic parameter of the roll design is intelligently produced by the method, and the finite representative parameters in the production can be used for predicting and fitting for roll shape processing parameters and technique parameters of different specifications of products. The times of trial rolling can be reduced and the preparation period of technology and manufacture can be shortened.

Description

technical field [0001] The invention relates to a method for designing roll profiles of ASSEL rolls based on genetic neural network technology. Background technique [0002] At present, my country's seamless steel pipes are moving from a big producer to a powerful one. China has the world's most advanced pipe rolling units, but these units are basically fully imported. The speed of absorption, digestion, localization and innovation is relatively slow. The main process technology software and key equipment still rely on imports, forming an introduction-re-introduction model, failing to form a benign situation in which imports promote domestic development. The progress of my country's seamless steel pipe production technology research, development of new varieties and equipment localization lags behind the development of seamless steel pipe production and market demand. [0003] For the new ASSEL unit, the roll is the most important rolling tool. The production practice has...

Problems solved by technology

Although the German MEER company provided the roll shape diagram of the ASSEL unit, it is extremely inconsistent with the actual production method of small batches, multiple varieties, multiple specifications and a wide range of product structures, especially not satisfying the internal surface quality of steel pipes with a wall thickness of less than 25mm requirements

The modified design of the roll often requires manual design based on experience, which brings problems. First, it is difficult to achieve an optimal design at one time. Second, the work efficiency is low and the design cycle is long.
