通过对氧化物冶金技术在高强度低合金钢生产中的试验研究,探索采用氧化物冶金技术冶炼过程中转炉终点及LF精炼过程钢中的氧含量控制、正确的脱氧方式、脱氧合金元素的加入时机等,通过调节钢液成分,确保形核诱导粒子的生成;同时,利用扫描电镜分析了钢中夹杂物的成分、形貌、尺寸及夹杂物周围的组织形貌,并对试验钢板的性能进行了取样检测。结果表明,试验炉次氧化物冶金的效果良好且试验钢板性能很好。
Through the experimental research of oxide metallurgy in the production of high strength and low alloy steel, the oxygen content control in the end of the converter and the process of LF refining steel in the smelting process of oxide metallurgy was explored. The correct deoxidation mode and addition of deoxidizing alloying elements Timing and so on, by regulating the composition of molten steel to ensure the formation of nucleation-induced particles; the same time, using scanning electron microscopy analysis of steel inclusions in the composition, morphology, size and inclusions around the microstructure, and test the performance of steel A sampling test was carried out. The results show that the test furnace sub-oxide metallurgy works well and the test plate performance is good.
