1凝壳熔炼在凝壳熔炼过程中，随着炉料的熔化，熔融的金属钛与冷的批捐壁接触而凝固成一层凝壳，阻止了熔融金属与增朗材料反应对钛造成的污染。当熔化需要数量的金属之后，将增涡中的熔融钛倒入策模或错型．在凝壳熔炼过程中，被难熔的氧化物和氨化物所污染的科块和密度大于钛 In the process of crust melting, as the charge material melts, the molten titanium metal and the cold donation wall come into contact with each other and solidify into a layer of crust, which prevents the pollution caused by the reaction between the molten metal and the bentonite material. After melting the required amount of metal, the vortexed molten titanium is poured into a mold or mold. In the skull melting process, refractory oxide and ammoniated contaminated section and the density of titanium than titanium
