鞍钢的这台电渣炉,按原设计用五千千伏安单相变压器,可重熔截面在28～35万毫米~2的自耗电极,重熔吨位可达8～13.5吨的扁锭。但初建的电渣炉,经初试生产,将变压器选用8级(最高的级数,110伏),重熔6吨的扁锭时,钢锭表面折痕严重,表面质量极坏,远远满足不了生产上的需要。这充分说明了二次短网中压降太大,直接影响有效功率。原设计的二次短网分布情况如图1。
The Ansteel electroslag furnace, according to the original design with a single-phase five-volt transformer, reusable cross-section of the consumable electrode 28 ~ 350,000 mm ~ 2, remelting tonnage of up to 8 ~ 13.5 tons of ingot . But the newly built electroslag furnace, the first trial production, the transformer selected 8 (the highest series, 110 V), remelting 6 tons of ingot, the ingot surface crease, the surface quality is very bad, far to meet No production needs. This fully shows that the secondary short-circuit pressure drop is too large, a direct impact on the effective power. The original design of the second short network distribution shown in Figure 1.
