在实际装容15吨的炼钢生产电弧炉上,对45钢进行了两种不同脱氧工艺的对比试验研究(20炉),为电弧炉冶炼一般钢种采用新的脱氧工艺提供了新的依根。一、脱氧工艺与研究方法 1、脱氧工艺原脱氧工艺(称“老工艺”)是碳粉、硅粉扩散脱氧为主,兼用铝、硅、锰进行沉淀脱氧的综合脱氧法;试验工艺(称“新工艺”)的主要特点是,全用铝强制钢液脱氧(予脱氧插铝1公斤/吨,终脱氧插铝0.5公斤/吨)、硅、锰
In the actual capacity of 15 tons of steelmaking electric arc furnace, 45 steel was carried out two different deoxidation process comparative study (20 furnaces), for the EAF smelting general steel with a new deoxidation process provides a new root. First, the deoxidation process and research methods 1, the deoxygenation process Deoxidation process (called “old process”) is the carbon powder, silicon powder diffusion deoxidation, and the use of aluminum, silicon, manganese deoxidation precipitation comprehensive deoxygenation; test process “New Process”) is characterized by the full use of aluminum forcing steel liquid deoxidation (to deoxidation inserted aluminum 1 kg / tonne, final deoxy inserted 0.5 kg / tonne), silicon, manganese
