摘要： PROBLEM TO BE SOLVED: To eliminate the metal with a low melting point in the molten bath of cast iron which is molten in a crucible induction furnace. SOLUTION: In a crucible induction furnace which melts the raw material of cast iron containing the steel sheet plated with zinc or lead, the inactive gases of 10-16 normal liter/min per unit bath quantity are blown in, when eliminating the metal with a low melting point such as zinc in a molten bath by blowing inactive gases into the molten bath in a melting chamber. In this case, the inside of the melting chamber should be decompressed to 8,700-16,700 pascal by being exhausted to eliminate the metal with a low melting point. By this means, zinc or lead can be eliminated to the allowable content to obtain a high quality molten bath of cast iron between charging stock and draining the molten bath.

摘要： PROBLEM TO BE SOLVED: To provide a method for separating zinc from a galvanized steel scrap in which zinc can be efficiently removed without dissolving and sticking iron. SOLUTION: The method for separating zinc from a galvanized steel scrap includes heating the scrap from the temperature (770°C) showing the magnetic transformation point of iron to the temperature (910°C) showing the transformation point from α-iron to γ-iron in the presence of a reducing agent in a dezincification furnace 11, reducing zinc oxide contained in the galvanized steel scrap to convert it to metal zinc, and separating the metal zinc by volatilization. The reducing agent is carbon such as carbon powder. The amount of the reducing agent to be added is preferably 0.1-10 mass% based on the galvanized steel scrap. The pressure in the dezincification furnace 11 is preferably set to ordinary pressure to a reduced pressure of 101.15-81.25 kPa. The inside of the dezincification furnace 11 is preferably set to a reducing atmosphere or an inert gas atmosphere. COPYRIGHT: (C)2010,JPO&INPIT
