Abstract This subject adopts the virtual simulation system of 120 t converter steelmaking。

The software adopts the industrial control software for research and development platform, embeds Operation procedures for the complete process of implantation, integrates special research and development process numerical simulation mathematical model, and establishs a rigorous scientific operation skills examination system。

Through the study of virtual simulation system of converter steelmaking, calculate the amount of raw materials to determine the ratio of various raw materials on the basis of material balance, heat balance, and finally simulate converter steelmaking process through the computer software。On the basis of familiar with the smelting process and the operation of skilled software, according to the requirements of the quality parameters of the steel at the end, optimize the converting process of the oxygen lance scramble, oxygen flow rate, oxygen blowing time, adjust the bottom blowing stirring intensity, according to the real-time numerical monitoring system for numerical operations, with good end-point control and judgment ability, accurate tapping, and finally complete deoxidation alloying operation。

The study through a large number of simulation practice, optimization of process parameters, meets the smelting target steel composition content as the ultimate goal。 At the same time, save the cost of smelting。
