钢包精炼炉温度变化数值模拟

Mathematical Simulation on Steel Temperature of LF Process

针对钢包精炼炉处理过程中钢水的温度变化进行数值模拟,得出了其主要生产过程的数学模型。模型计算结果与生产数据的比较表明该数学模型符合实际生产状况。钢包炉温度模型计算结果说明,生产过程中提供给精炼炉的电弧加热时间不很充裕,要在有限的时间内达到要求的钢水温度,需要使用较高的电弧输入功率,并要采用理想的埋弧精炼工艺。处理过程中温降梯度最大的时段是精炼渣料的加入阶段,如果为了其他目的而过分增大精炼渣的用量,在处理时间内达到要求的精炼终点温度将有一定的困难。

The steel temperature mathematical model of LF process was obtained.The comparison between calculated results and actual data showed that the obtained models were corresponded with the actuality.So the models were reliable for theoretical analysis.Calculated results of temperature prediction model showed,much higher input power and foaming refining technology should be used to achieve the production requirement.In treatment process,the most temperature gradient slot was the time adding refining slag.If excessive slag were added into ladle,there would be some difficulty to achieve end-point temperature.
