摘要： The invention provides a raw materials feeding apparatus capable of uniformly dispersing and feeding into a furnace agglomerated raw materials that are likely to undergo dusting, deformation and mutual adhesion. In a raw material feeding apparatus for a rotary hearth furnace, for feeding raw materials to a rotary hearth furnace by using a flat belt conveyor, the invention employs a construction in which a scraper for guiding the raw materials on the flat belt conveyor to a side surface of the flat belt conveyor is arranged obliquely to a traveling direction of the flat belt conveyor. Preferably, the scraper is arranged in such a manner as to guide the raw materials to both sides of the flat belt conveyor.

摘要： Provided is an electric arc melting facility in which a source iron can be melted with high thermal efficiency and supply of the source iron from a preheating chamber to a melting chamber can be controlled and an operation method for the molten metal using the electric arc melting facility. An electric arc melting facility 1 includes a melting chamber 2 configured to melt a source iron therein, a shaft-shaped preheating chamber 4 directly connected to the melting chamber, and an electrode 3. At least a part of a bottom surface of the preheating chamber 4 is formed as an inclined bottom surface 7a inclined downward toward the melting chamber 2. A shaft opening dimension H is set to an optimum value for controlling the supply of the source iron. A pushing device 6 is disposed at a lower side of the preheating chamber 4 and configured to move the source iron toward the melting chamber 2. The source iron is supplied from the preheating chamber 4 to the melting chamber 2 when the pushing device 6 is operated. The supply of the source iron from the preheating chamber 4 to the melting chamber 2 is stopped when the operation of the pushing device 6 is halted. The optimum value of the shaft opening dimension H is set so as to satisfy the relationship "A ‰¤ H ‰¤ 4A", where A is a maximum length of the source iron.

摘要： Disclosed is a molten metal producing device capable of effectively preventing a hanging of a metal agglomerate raw material layer and capable of reliably removing hanging even if the hanging occurs. Raw material for forming the raw material layer (A) and metal agglomerate raw material (B) are charged in this order from raw material charging chutes (4,4) at either end portion (2,2) of a stationary non-tilting arc furnace in the width direction of the furnace so as to form raw material layers (12) each having a sloping surface extending downward to the portions of electrodes (5) disposed in a central region in the furnace width direction and metal agglomerate raw material layers (13) on the slopes, respectively. Molten iron is produced by sequentially melting lower end portions of the metal agglomerate raw material layers (13) by arc heating at the electrodes (5). At the same time, an oxygen containing gas (C) is blown from secondary combustion burners (6) in a furnace top (1) so as to cause the combustion of a CO containing gas generated from the metal agglomerate raw material layers (13) while the metal agglomerate raw material layers (13) descend along the sloping surface of the raw material layer (12), and the metal agglomerate raw material layers (13) are heated by the radiant heat of the secondary combustion. Shock generators (18) are disposed above a molten slag layer (15) and below surfaces of the metal agglomerate raw material layers (13) inside the furnace.
