摘　　要：对本公司近期抽锭式结晶器所生产的大直径电渣锭所展开的技术研究进行了总结。抽锭式结晶器生产电渣锭,生产过程中抽锭过程、换坯过程都存在着较大的漏渣、流钢风险,故渣系的选择至关重要,且由于大锭型冶炼时间较长,渣系的改变、渣量的损失都对冶炼过程控制产生影响。此类抽锭式结晶器工艺所选择的熔速、充填比、交换电极坯工艺等,都对冶炼过程产生着影响。This paper summarizes the technical research on large-diameter electroslag ingots produced by our company recently.In the process of electroslag ingot production by the extraction mold,there are great risks of slag leakage and steel flow in the process of ingot extraction and billet change,so the selection of slag system is very important.And because the large ingot smelting takes a long time,the change of slag system and the loss of slag amount have an impact on the smelting process control.The melting rate,filling ratio and the process of exchange electrode blank used in this kind of ingot drawing crystallizer process all have an impact on the smelting process.
