Rigid line product microscopic structure and mechanical property fore casting system

Abstract

The invention relates to a temperature, texture and performance forecasting system for directly rolling high carbon steel wire using continuous cast blank, and its solution: taking rolled piece for testing and analyzing microstructure and mechanical performance, and determining surface temperature of the rolled piece; establishing a temperature model, an austenitic texture developing model, an austenitic resolving model and a mechanical performance-microscopical texture relation model for directly rolling high carbon steel wire by continuous cast blank; writing a control program for hard wire mcroscopical texture development and wire mechanical performance forecast in VB language and simulating the rolling; then respectively giving all the temperature data, wind cooling speed, cooling water quantity, deforming speed and deforming quantity. The invention has the characters of forecasting microscopical texture and mechanical performance of high carbon steel wire and being able to propose corresponding control range of process parameters.

Description

1. Technical field [0001] The invention belongs to the technical field of steel rolling. In particular, it relates to a temperature, structure and performance prediction system for direct rolling of high-carbon steel wire rods with continuous casting slabs. 2. Background technology [0002] Prediction of steel microstructure and properties is a hot research topic at home and abroad, and it is one of the important directions for the development of my country's steel rolling technology (Zhang Shutang, my country's Steel Rolling Technology Facing the 21st Century, Iron and Steel, 1999.10). The research on the mathematical model of the hot rolling process began in the United Kingdom in the 1970s, and in the 1980s Europe developed a hot rolling structure and performance prediction system. In the 1990s, the Metallurgical Process Engineering Center of the University of British Columbia in Canada, the US National Bureau of Standards and 14 North American steel companies jointly dev...
