在250公斤工频感应炉中用低碳钢返回料熔炼45~#钢,在钢料熔化过程中常有钢液爆溅现象,随即加少量铝止爆,出钢前插铝终脱氧,用此法连续熔化了几炉后炉子功率下降,熔化缓慢,随着熔炼炉数的增加,炉壁和炉底由于炉渣粘结,而逐渐增厚形成堆积物,因此炉膛有效容积减少,炉子功率下降更大,熔化越来越慢,既影响了出钢量也影响了钢的质量。对炉衬堆积物进行分析,其主要成份是Al_2O_3,CaO_2,SiO_2等氧化物。可以认为这种炉衬堆积物是脱氧生成非磁性的比重轻的高熔点产物所造成的。我们通过对工频感应炉的电磁感应特性的
In 250 kilograms of frequency induction furnace with low carbon steel return material smelting 45 ~ # steel, molten steel often molten steel splashing phenomenon, and then add a small amount of aluminum explosion, tapping the aluminum before the final deoxidation, with this After several consecutive furnaces melting, the power of the furnace dropped and melted slowly. As the number of melting furnaces increased, the furnace walls and bottom of the furnace gradually became thicker due to the bonding of the slag, resulting in a decrease of the effective volume of the furnace and a decrease of the furnace power Large, more and more slow melting, both affect the amount of steel also affects the quality of steel. Analysis of the lining deposits, the main ingredient is Al 2 O 3, CaO 2, SiO 2 and other oxides. It is believed that this lining deposit is deoxidized to produce a non-magnetic, high-melting-point product having a low specific gravity. We pass the frequency induction furnace electromagnetic induction characteristics
