百吨级钢锭的新一代连铸液态电渣技术展望
Development of Electroslag with Liquid Metal for 100-ton Ingots
传统双支臂电渣重熔生产百吨级铸锭时,由于金属母材存在交替熔炼过程,交替时刻因电流中断极易引发铸锭的表面渣沟、铸锭内部夹渣等典型问题,限制了百吨级铸锭的制备。本文提出了新一代电渣液态浇铸技术,采用双感应熔炼坩埚,依次交替向导电结晶器内持续的提供稳定的钢液,能够实现电渣重熔的持续稳定进行。基于前人对电渣液态浇铸的研究,探讨了本文提出的新一代电渣液态浇铸的导电方式、熔化速率、钢液浇注温度等工艺对铸锭质量的影响规律。本文旨在为熔炼百吨级铸锭的提供一种新工艺。
During the traditional double-arm electroslag remelting producing 100-ton ingots,due to the alternate melting process of the metal electrode,the typical problems such as the surface of ingot and slag inclusion in the ingot are easily caused by the interruption of the current at the alternate time,which limits the preparation of 100-ton ingots.In this paper,a new generation of electroslag with liquid metal is proposed,which uses double induction melting crucibles to alternately guide the continuous supply of stable molten steel in the electric crystallizer,and can realize the continuous and stable process of electroslag remelting.Based on the previous research on electroslag with liquid metal,the influence of the new generation of electroslag with liquid metal process,such as conductive mode,melting rate and pouring temperature of molten steel,on the ingot quality was discussed.This paper aims to provide a new process for remelting 100-ton ingots.
