    • PURPOSE: A steelmaking arc electric furnace is provided in which temperature is uniformly elevated rapidly up to melting temperature of a material to be melted without reducing the furnace strength, and time for melting and refining can be shortened. CONSTITUTION: The steelmaking arc electric furnace is characterized in that a refractory layer (2) is provided as lining on a lower surface (B) on the hearth side of a shell (1) of the arc electric furnace, a refrigerant flow path is built in the furnace-wall upper face (A) of the shell (1), an oxygen gas supply pipe penetrating the shell (1) is connected to an oxygen gas dispersing supply chamber, a number of oxygen gas outlets (11) directing to the material to be melted are peripherally provided in an oxygen gas dispersing supply chamber, and a refrigerant circulation panel (3) is provided as lining at an optional place of the chamber.
    • 目的:提供一种炼钢电弧炉,其中,在不降低炉子强度的情况下,将温度迅速均匀地升高至待熔融材料的熔融温度,并且可以缩短熔炼和精炼时间。 构成:炼钢电弧炉的特征在于,在电弧电炉的壳体(1)的炉床侧的下表面(B)上设置耐火层(2),构成制冷剂流路 在壳体(1)的炉壁上表面(A)中,穿过壳体(1)的氧气供给管连接到氧气分散供给室,多个氧气出口(11)指向 在氧气分散供给室中周边配置要熔融的材料,在室的任意位置设置制冷剂循环板(3)作为衬里。
