摘要： PURPOSE:To eliminate a dangerous state of discharging work and make a stable operation of a furnace by a method wherein a discharging port is sealed at its liquid surface with molten metal or slag in a main furnace and the metal is discharged to a molten metal storing container communicated continuously through the molten metal accumulation part in the main furnace and the discharging hole. CONSTITUTION:A main furnace 1 and a molten metal storing container 5 are communicated with a discharging hole 6. Molten metal passes through the discharging hole 6, exceeds a discharging bank 7 of the container 5 and then is discharged. A height of the discharging bank 7 is set in reference to a molten substance, a static pressure in the furnace and an agitating effect of molten metal, and an increased amount of molten product within the furnace is continuously taken out of the furnace while the blowing of the furnace gas is not occurred through the discharging hole 6. A temperature control device 13 is arranged in the container 5 so as to control a discharging temperature of the molten metal and slag. With such an arrangement, a dangerous condition of the discharging work can be eliminated and at the same time a difficult operation caused by a disturbed temperature and pressure in an entire plant can be eliminated.

摘要： PURPOSE:To produce molten pig iron with good thermal efficiency without using any rotary kiln by adding carbonaceous reducing agents and desulfurizers to pellets of residual oils formed from powder iron ore and residual oils and subjecting the mixture to drying, carbonizing and reducing then to melting. CONSTITUTION:Powder iron ore O and residual oils R are mixed by a pelletizer 1, whereby residual oil pellets PR are formed. If necessary, the pellets PR are carbonized in a moving grate furnace 2 for drying and carbonizing and are charged together with carbonaceous reducing agents C and desulfurizers Fl consisting of limestone or dolomite, etc. into a shaft and melting furnace 4 by means of a mixer 3. The materials that are not dried and carbonized in the furnace 2 are dried and carbonized in the uppermost part of the furnace 4. The mixture charged in the furnace 4 is reduced by a reducing gas G in the shaft furnace 4A, and are melted by an induction coil 6 in the melting furnace 4B, whereby the mixture is separated to molten iron PI and slag Sl. Part of the light oil produced by cracking from the pellets PR in the furnace 4A is modified with a heating and modifying furnace 7 and is used as the gas G.

摘要： PROBLEM TO BE SOLVED: To withdraw a metallic product sufficiently separated from slag in molten producing material so as to be possible to charge into the following process. SOLUTION: A water vessel stored water 21 at a prescribed water level is prepared and a mold 30 is prepared in the stored water 21. The molten producing material is poured into the mold 30 in the stored water 21 from the ejecting end of a melting furnace 10, and the molten metal is separated from the slag by the difference between both sp. grs. before both of the molten metal and slag solidify in the mold 30. Thus, the separation casting process for casting the molten metal into the blocky metallic product having prescribed size and shape, is obtd.

摘要： PURPOSE:To assure a sufficient and uniform keeping of staying time for a material to be processed within a furnace by a method wherein an induction coil is wound around a furnace wall about an imaginary axis forming a certain angle in respect to a central axis, a height difference is provided at the induction coil position at the furnace wall, a feeding port for the processed material is disposed at the furnace wall at a higher location of the induction coil and then a discharging hole is disposed at the furnace wall of a lower position. CONSTITUTION:An upper agitating action is increased in a melting metal corresponding to a higher position of an induction coil under an action of an electromagnetic field of the induction coil 11 and then a melting surface is made high as compared with that of melting metal corresponding to a lower position in the induction coil. As a result, the melting metal has a surface gradient decreasing from a part near the inlet port 13 for materials to be processed toward a discharging hole 12. With such an arrangement, a gradual flow divided into two segments form a part just below the feeding inlet port for the processed material along a circumferential edge of a furnace wall is formed at the melting metal surface and then a sufficient staying time is assured along with the upper or lower agitating action.
