摘要
在冶炼硅钢时,残余的Ti元素会对硅钢最终的磁性能产生不利影响,因此在冶炼硅钢时要对Ti含量进行严格控制,尽可能降低Ti含量。文章共统计了60炉分为不同渣层厚度的硅钢中,在加入硅铁及铝铁后Ti含量数据,分析了有害元素Ti含量来源和增量。随着硅钢牌号的提高,硅钢中硅含量随之增加,导致硅铁合金加入量增加,Ti含量因此随之升高;同时减少渣层厚度,对于钢水终点Ti含量的控制有着至关重要的作用。
There are adverse effects of residual Ti on the final magnetic property of silicon steel,so the Ti content should be strictly controlled to be as low as possible when smelting silicon steel.In the paper,the sources and increment for the content of harmful element Ti are analyzed based on the data of Ti content after adding the ferrosilicon and ferro-aluminium into 60 heats of silicon steel with different thicknesses of slag layer.With the increase of silicon steel grade,the Si contentin in siliconstal is increased and the quantity of the ferrosilicon added is also increased so that the Ti content rises correspondingly;it is crucial for controlling the end-point Ti content of molten steel to reduce the thickness of slag layer simultaneously.
