摘要： A scrap melting method for producing hot metal by using scrap as an iron source, pulverized coal as a main heat source and/or as a high calorie exhaust gas source, and synthetic resins, which are wastes, as a high calorie exhaust gas source and as a part of the heat source and obtaining high calorie exhaust gas having high utility value as a fuel gas, characterised in that a shaft furnace having a combustion burner at a tuyere is used, that scrap and coke as iron sources are supplied into the furnace from a top portion thereof while a synthetic resin material is supplied as required, that pulverized coal or pulverized coal and the synthetic resin material and oxygen are blown from the combustion burner under a specific condition so that pulverized coal or pulverized coal and the synthetic resin material and oxygen can be mixed together to thereby have pulverized coal and the like burned quickly, that scrap is melted by sensible heat of the combustion gas to produce hot metal and that the secondary combustion of combustion gas inside the furnace is intentionally prevented to thereby recover it as fuel gas.
