水冷炉盖虽然提高了电炉炉盖的使用寿命,节约了耐火砖和修砌时间,但水冷炉盖的循环水带走了大量的辐射热,使电炉耗电量增加。尤其在还原期,经常出现短路,击穿炉盖内层钢板,导致漏水,不得不中途停电抢修。在连续开炉的情况下,水温高达 Although the water-cooled lid increases the service life of the electric furnace lid, saving firebrick and repair time, but the circulating water of the water-cooled lid takes away a large amount of radiant heat, so electric furnace power consumption increases. Especially in the reduction period, often appear short circuit, breakdown inside the steel plate, resulting in water leakage, forced to repair midway. In the case of continuous open furnace, the water temperature up
