电渣重熔过程中脱氧对低铝控制的影响

INFLUENCE OF DEOXIDATION ON CONTROLLING LOW AL DURING ESR PROCESS

研究了工业生产条件下,特别是200t级大型电渣炉重熔过程中脱氧对低Al(≤0.010％)控制的影响。指出在正常的电渣重熔过程中,低AI控制与脱氧剂种类、渣中FeO含量和自耗电极中的Si/Al值没有明显关系,采用特殊的电渣重熔技术重熔,是控制低A1的关键。

The influence of deoxidation on controlling low Al (≤0.010%) has been investigated under the commercial conditions, especially, during the 200 ton large ESR furnace remelting, it is demonstrated that during normal ESR processes low Al control has no evident relations to types of deoxidants, FeO contents in slags and Si/Al values in consumable electrodes. It is the key measure to adopt a special ESR technique to control low Al.
