摘要: 本文基于RH脱硫剂、RH脱硫过程和无取向电工钢的应用过程,以脱硫量0.001 5 %、脱硫剂加入量7.5 kg/t为例,对CaO-CaF2系和铝酸钙系脱硫剂分别进行了碳排放量的测算。测算结果表明:铝酸钙系脱硫剂和CaO-CaF2系脱硫剂生产的碳排放量分别为2.362 kg CO2/kg和0.788 kg CO2/kg;RH脱硫剂使用过程中,铝酸钙系脱硫剂和CaO-CaF2系脱硫剂使用过程的平均碳排放量增加约为405 kg CO2/ t和416 kg CO2/t。本文还针对无取向电工钢在使用过程的碳排放进行了粗略测算。测算数据对阐述RH脱硫工艺的重要性有参考意义。

Abstract: Carbon emission calculation was done in this paper by analysis of RH desulphur process, fluxes and application of electrical steel. The set conditions are of 0.001 5 % decrease of sulphur content, flux addition amount of 7.5 kg/t steel, and calcium aluminates and CaO-CaF2 combination were chosen. The results showed in consequence that the production of the two fluxes generate carbon emission of 2.362 kg CO2/kg and 0.788 kg CO2/kg, and that of 405 kg CO2/ t steel and 416 kg CO2/ t steel during flux desulphur application process. The carbon emission in use of silicon steel was also discussed and estimated, which says RH desulphur process is playing important role in silicon steel production.
