摘　　要：通常大型板坯电渣炉钢锭断面尺寸(mm)为:(400～950)×(800～3 200),锭重5～70t。文中分析了大型板坯电渣重熔炉炉型和钢中氢含量、铸锭偏析、表面质量控制等工艺特点。目前大型板坯电渣重熔炉供电方式以单相双极串联为主,具主要特点为操作简单可靠,感抗损失小,用电效率高,钢水过热度小,结晶质量好。In general the section sizes of ESR furnace ingot for heavy slabs are （ram） ： （400 - 950） × （800 - 3 200） with weight 5 - 70 t. The furnace type of ESR furnace for heavy slabs and the process characteristics such as control of hydrogen content in steel, ingot segregation and surface quality are analyzed in this paper. At present the main power supply method for ESR furnace of heavy slabs is single-phase hi-electrode connecting in series, of which the main characteristics are operating simply and reliably less inductive resistance loss, higher power efficiency, small overheat of liquid steel and nice crystal quality.
