<p>A method for minimizing cold spot of a minimill electric furnace and a sub-material supply device are provided to activate the slag foaming by promoting the reaction between an ingot steel and a supplementary raw material. A method for minimizing cold spot of a minimill electric furnace is to input a supplementary raw material when the slop of a furnace body is 4° and 60% of the scrap charged in the electric furnace is dissolved. A subsidiary input conduction plate(10) connects to a side surface of a hole lid(25) of an input port(26). An input hole of cylindrical shape passes through the inside of the subsidiary input conduction plate.</p> |
