<p>PURPOSE:To reduce cost and to improve productivity by subjecting the scrap in a furnace body to initial melting by an arc, storing a prescribed amt. of the molten scrap, blowing a carboneous material and oxygen into a molten steel and melting the remaining scrap by the combustion energy generated by the combustion of CO. CONSTITUTION:The scrap in one of the plural furnace bodies is initially melted by the arc and a prescribed amt. of the molten steel is stored in one furnace body by the initial melting. The carboneous material and oxygen are blown into the molten steel to generate the combustion energy by the combustion of CO. The remaining scrap in the one furnace body is melted by such combustion energy. The heating of the scrap in the other furnace body is executed by the combustion of the CO in the waste gas generated by the initial melting or the waste gas contg. the CO and the preheating of the scrap in the one furnace body is executed by the waste gas from the other furnace body.</p> |
