During the period of electric furnace smelting, the taphole filler of the contact part with the molten steel produced the sintering layer, thus preventing the molten steel from penetrating downwards. The non sintered taphole filler under the sintering layer can flow smoothly when the steel plate is opened by the tapping, and the sintering layer is broken by the pressure of the molten steel to achieve the purpose of automatic pouring. When the electric furnace is finished tapping, when the stuffing is put into the EBT platform, the refractory material taphole filler can flow out of the tapping hole automatically, and the molten steel flows into the ladle. The automatic casting rate can reach more than 90%.
