我厂电炉原为3吨容量,由于生产任务的发展,钢的需要虽大大增加.我们将变压器自900KVA换成2500KVA,这样变压器就足可满足5吨容量的电炉使用.而机械能力经测定亦无问题.为了要满足这种需要,将熔化室加以改变.根据斯达哈诺夫炼钢工的经验,用镁砂将炉门堵起以扩大熔化室,因此大小炉门常常用300公 Our factory electric furnace was originally 3 tons of capacity, due to the development of production tasks, although the demand for steel increased significantly. We will be replaced from 900KVA transformer 2500KVA, so that the transformer is sufficient to meet the electric capacity of 5 tons of furnace use. No problem.In order to meet this need, the melting chamber was changed.According to the experience of the Stakhanov steelmakers, the magnesia was used to block the furnace door to enlarge the melting chamber, so the size of the furnace door is often 300
