摘要

以45t AOD-L冶炼304不锈钢的实际生产数据为依据

根据系统模化、质量、能量守恒及热力学原理

建立了AOD冶炼奥氏体不锈钢的工艺模型(AOD M&H)

包含操作、化学反应、冶金计量和热化学计量4个层次

共涉及469个变量。使用该模型进行模拟

由139项输入变量

包括各物料的用量、成分和温度

可方便地求出39项输出变量

如钢液成分、温度等。应用结果表明

冶炼过程中各阶段的钢液碳含量与温度的预报值和实测值的相对误差≤11.1%。

Abstract

Based on practical production data of steelmaking process for 304 stainless steel by a 45 t AOD-L unit

according to system modeling

conservation of mass and energy

and thermodynamic principle

a processing model (AOD M&H) for austenite stainless steel steelmaking by AOD process has been established including four levels: operation

chemical reaction

metallurgy and energy computation with 469 variables. With 139 input variables including amount

ingredient and temperature of each material

the 39 output variables such as chemical composition and temperature of liquid steel etc. can be calculated by the model. Application results showed that the relative error of carbon content and temperature of liquid steel in each phase of steelmaking process between calculated and measured value was ≤11. 1 %.
