    摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a molten metal at low cost by melting a reduced hot metal discharged from a direct reducing furnace in a melting furnace around it, which does not need an expensive facility for transporting the reduced metal from the direct reducing furnace to the melting furnace, and does not cause aggravation of a melting yield and a working environment.
    SOLUTION: This method for manufacturing the molten metal comprises accommodating the reduced metal in as hot condition into a metal container 5 such as a wasted storage drum, which has been discharged from the direct reducing furnace 1, while cooling the surface of a container 5 with water as needed, into 500°C or lower, transporting the container 5 filled with the reduced metal to the melting furnace, and charging it together with the container into the melting furnace to melt them.

    摘要： PURPOSE:To provide a continuous steel making device which stabilizes components and temp. and enables the stable operation of a continuous steel making furnace by consisting the same of a cupola as a supply source for molten steel, a molten iron holding furnace and the continuous steel making furnace. CONSTITUTION:Steel scrap, cast iron scrap, etc. are used as main materials in a cupola 5. Coke 2 as fuel and limestone 3 as a slag forming agent are mixed and the mixture is charged almost continuously from the furnace top by means of a charging basket 4. On the other hand, air is supplied through plural tuyeres 7 in the lower part and the main materials 1 are melted. Molten metal 8 is tapped continuously and is once stored in a molten iron holding furnace 9 provided with a heating source 10 by which the temp. and components are made uniform. Each specified amt. of the molten metal is charged 8' from a changeover spout 11 continuously into a continuous steel making furnace 12. The molten iron 8' is continuously refined in the furnace 12 and is tapped as molten steel 15. The molten steel is further stored in a component adjusting furnace 16 and molten steel 17 which is a product is obtd. after the component adjustment. The components of the molten steel 17 are always analyzed with an analyzer 20 and an oxygen supply valve 22 is controlled with a controller 21 by the comparison with the standard components of the product, whereby the supply rate of oxygen is adjusted and the refining reaction is controlled.
