MODELLING OF TECHNOLOGICAL PROCESSES FOR COPPER ROD PRODUCTION

Abstract

Purpose

The main purpose of this study is to develop an information model of technological processes for monitoring and optimizing production tasks.

Design/methodology/approach

Mathematical modelling of melt flow processes in technological equipment is based on the Navier-Stokes equations. The Galerkin method was used to solve the hydrodynamic equations with appropriate boundary conditions and obtain a priori estimates.

Findings

A physical and mathematical model of molten metal motion in process equipment has been developed. A computer program for the numerical solution of hydrodynamic equations has been developed. An information model for monitoring and optimizing of technological processes in process equipment has been developed based on numerical experiments.

Practical application

The developed information model has been verified and was constructed for Zhezkazgantsvetmet Production Association Branch of Kazakhmys Corporation LLP continuous rolling lines for copper rods. The empirical and numerical calculations show that the best melting occurred at 1556 [K].

Originality/Value

This study fulfils the need for addresses the problem of copper sticking to the chute during the hot rolling process by investigating the key technologies intended to improve the production line process of copper rods. The application of the developed melt processing method has a positive effect on the product quality.
