在转炉内冶炼超低硫钢日本新日铁公司发明了一种在转炉内冶炼超低硫钢的方法。冶炼过程分成２个阶段：在第１阶段当铁水含碳量降至０．３％～２．５％时，加入脱硫剂进行脱硫处理，然后把脱硫渣清除。在第２阶段，加入脱磷剂进行吹氧冶炼，最后得到成分合乎规定的钢水。第... Smelting ultra low sulfur steel in a converter Nippon Steel Corporation of Japan invented a method of smelting ultra low sulfur steel in a converter. Smelting process is divided into two stages: In the first stage when the molten iron carbon content decreased to 0.3% ~ 2.5%, the desulfurization agent was added for desulfurization, and then remove the desulfurization residue. In the second stage, adding dephosphorizer oxygen blowing smelting, and finally get the composition of the required molten steel. The first ...
