摘要
低Al含量的控制是电渣重熔过程中的难点,针对低Al焊丝钢ER90S、TT65-G和低Al不锈钢1Cr21Ni5Ti,对Al含量的控制进行了研究。在500 kg电渣重熔炉内,分别采用CaF_(2)-Al_(2)O_(3)-CaO-SiO_(2)渣系和CaF_(2)-Al_(2)O_(3)-CaO-MgO-TiO_(2)渣系熔炼了低Al焊丝钢和低Al不锈钢。结果表明,经CaF_(2)-Al_(2)O_(3)-CaO-SiO_(2)(57∶20∶20∶3)渣系冶炼的高Si、高Mn、低Al焊丝钢的钢锭Al含量均小于0.015%。经CaF_(2)-Al_(2)O_(3)-CaO-MgO-TiO_(2)(51∶20∶20∶3∶6)渣系冶炼的高Ti、低Al不锈钢的钢锭头尾Al增加量均小于0.02%。
The control of low-Al content is difficult in the process of electroslag remelting.The control of Al content in low-Al wire steel ER90S,TT65-G and low-Al stainless steel 1Cr21Ni5Ti was studied.Low-Al wire steel and low-Al stainless steel were smelted by CaF_(2)-Al_(2)O_(3)-CaO-SiO_(2) slag system and CaF_(2)-Al_(2)O_(3)-CaO-MgO-TiO_(2) slag system respectively in 500 kg electroslag remelting furnace.The results show that Al content in ingot of high Si,high Mn and low-Al wire steel smelted by CaF_(2)-Al_(2)O_(3)-CaO-SiO_(2)(57∶20∶20∶3)slag system is less than 0.015%.The increase of Al in the ingot head and tail of high Ti and low-Al stainless steel smelted by CaF_(2)-Al_(2)O_(3)-CaO-MgO-TiO_(2)(51∶20∶20∶3∶6)slag system is less than 0.02%.
