本文主要研究稀土金属对实验室和工业试验的162Aφ低合金钢性能的影响。实验室试验钢在60公斤感应炉中冶炼,並浇注成15公斤钢锭,在浇注过程中添加混合稀土金属。钢锭在1200℃锻成截面为40×70mm板坯。然后沿纵向轧成11mm厚板材,並经930℃正火处理。工业试验钢在180吨转炉中冶炼,並在包中用合成渣处理。在吹氩时加入
This paper focuses on the effects of rare earth metals on the properties of 162Aφ low-alloy steels in laboratory and industrial tests. Laboratory test steel is smelted in a 60 kg induction furnace and poured into 15 kg ingots to add mixed rare earth metals during casting. The ingot was forged into a 40 × 70 mm slab at 1200 ° C. Then rolled into a 11mm thick plate along the longitudinal direction and normalized at 930 ℃. Industrial test steel is smelted in a 180-ton converter and treated with synthetic slag in the bag. Add when blowing argon
