结合唐山钢铁集团公司超低硫管线钢试验生产实践,介绍了全流程硫含量控制技术,指出了超低硫冶炼的关键控制点在铁水预处理和精炼,抗氢致裂纹的关键在于钢中夹杂物的控制。得出了通过全过程硫含量控制能够生产超低硫管线钢的结论。 Combined with the experimental production practice of ultra-low sulfur pipeline steel in Tangshan Iron and Steel Group Company, the sulfur content control technology in the whole process was introduced. The key point of the ultra-low sulfur smelting was pointed out that the key point in the pretreatment and refining of molten iron and hydrogen cracking was steel inclusion Control of things. It is concluded that the ultra-low sulfur pipeline steel can be produced through sulfur content control in the whole process.
