15吨钢包中喷吹矽钙粉的工艺,可以冶炼低硫、磷钢,使钢水中含硫量达到0.003％,个别硫接近痕迹。在冶炼低碳钢和低合金钢时,利用包中喷吹矽钙粉工艺可以取消电炉还原期。炉内只进行熔化和氧化过程,能缩短30分钟左右的冶炼时间,节电80度/T。(150公斤感应炉试验CaO+CaF_2可脱硫50％)。今后如能找到便宜的混合材料,再配入Al,Ca—Si和CaC_2可提高到60—80％。作为脱氧、脱硫剂,就会使喷射冶金的钢包处理具有更大的生命力。
15 tons of ladle in the process of spraying calcium silicate powder, you can smelt low-sulfur, phosphorus steel, the molten steel sulfur content of 0.003%, individual traces of sulfur. In the smelting of low carbon steel and low alloy steel, the use of packet injection of calcium silicate powder process can cancel the furnace reduction period. Only the furnace melting and oxidation process, can shorten the smelting time of about 30 minutes, saving 80 degrees / T. (150 kg induction furnace test CaO + CaF_2 desulfurization 50%). In the future if you can find a cheap mixture, then with Al, Ca-Si and CaC_2 can be increased to 60-80%. As deoxidation, desulfurization agent, it will make the ladle metallurgy spray treatment has greater vitality.
