两种渣系电渣重熔冶炼C-HRA-3 镍基合金锭冶金质量试验探究
Exploration of Metallurgical Quality Test for C-HRA-3 Nickel Base Alloy Ingot Smelted by Two Slag System Through Electroslag Remelting
本文利用实验室 10 kg级电渣重熔炉研究了两种六元渣系电渣重熔冶炼C-HRA-3合金冶金质量的差异。结果表明:相比于 60%CaF2-20%Al2O3-10%CaO-10%MgO(以下简称 6211 渣系)基础渣系,利用新型 50.4%CaF2-26.1%Al2O3-19.5%CaO-3%MgO基础渣系(以下简称新型渣系)电渣重熔冶炼C-HRA-3 合金表面质量更优,凹坑数量少且深度浅;新型渣系冶炼的电渣锭柱状晶生长方向与中心线夹角更小,熔池深…查看全部>>
In this paper,the difference in metallurgical quality of C-HRA-3 alloy smelting using two kinds of slag system was investigated by a 10 kg electroslag remelting furnace.The results show that the alloy electroslag ingot smelting by a new-type 50.4%CaF2-26.1%Al2O3-19.5%CaO-3%MgO basic slag system has better surface quality,where there are fewer pits and thier depth is shallower,compared to 60%CaF2-20%Al2O3-10%CaO-10%MgO basic slag system.The columnar crystal g…查看全部>>
