大型平炉熔炼室外壳,系一大体积的金属结构,内筑耐火砖砌体,直接承担高温钢水的冶炼工作,并与两侧的沉渣室及蓄热室等结构,共同组成平炉冶炼的生产体系。熔炼室基础系由两片支墩及底板组成的钢筋混凝土结构。支墩承受很大的熔炼室荷载,两支墩如有差 Large-scale open hearth melting chamber shell, a large volume of metal structure, built refractory brick masonry, direct smelting work of high-temperature molten steel, and with both sides of the slag chamber and regenerator and other structures, to form a flat furnace smelting production system . The base of the melting chamber is a reinforced concrete structure consisting of two support piers and floor plates. The pier is subjected to a large load of the melt chamber. If there is any difference between the two piers
