1.试验方法方法:试验用装入量为10.5吨的电弧炉和SGDF一Ⅱ型喷罐。共进行喷吹Ca—Si的试验61炉。以45、20号钢为对象,探索合理工艺参数。试验参数变动范围如下:钢水原始形态L氧化性钢水插A10一1.2kg/T后扒渣3/4出钢。还原性钢水出钢前插Al0.8kg/T。包中盖渣:随钢流投入1.25一1.5%的CaO+CaF_2,有时加0.5kg/TCa—Si粉和小于1.5kg/T的增碳剂,随钢流投入包中0一1.5kg/T的Al,还原喷吹时包中盖3%炉内熔化的
1. Test methods and methods: The test load capacity of 10.5 tons of electric arc furnace and SGDF a spray cans. A total of 61 furnaces were tested for blowing Ca-Si. 45,20 steel for the object, to explore the reasonable process parameters. Test parameters variation range is as follows: The original form of molten steel L oxidized molten steel plug A10 a 1.2kg / T after the slag 3/4 tapping. Reducing steel before tapping Al0.8kg / T. Package slag in the bag: with the flow of 1.25 to 1.5% of CaO + CaF_2, and sometimes add 0.5kg / TCa-Si powder and less than 1.5kg / T carbonation agent, with the steel into the bag 0-1.5kg / T Al, reducing the injection package melting 3% furnace cover
