Research on Tempering and Tempering of Induction Furnace of Intermediate Frequency Furnace

Abstract: The research information of quenching and tempering temperature adjustment of induction furnace of intermediate frequency furnace is provided by excellent manufacturers of flowmeters and flowmeters. Quenching and tempering: As the blast furnace smelting is strengthened, the chemical composition of the molten iron is basically guaranteed, which greatly reduces the difficulty of tempering and tempering in the induction furnace. However, in order to ensure the melting effect of the intermediate frequency furnace, the charging material of the intermediate frequency furnace should also be based on the chemical composition and inoculation technology of the casting. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the research articles on quenching and tempering of induction furnaces for intermediate frequency furnaces. Quenching and tempering: As the blast furnace smelting is strengthened, the chemical composition of the molten iron is basically guaranteed, which greatly reduces the difficulty of tempering and tempering in the induction furnace. However, in order to ensure the melting effect of the intermediate frequency furnace, the charging material of the intermediate frequency furnace should also be quenched and tempered by the intermediate frequency furnace on the basis of the laboratory analysis of the molten iron in the blast furnace according to the requirements of the casting's chemical composition and inoculation technology. Liquid iron composition: carbon 3.2%-3.45%, Si/C ratio around 0.65, S content greater than 0.07%. According to this, a strict batching calculation is carried out to determine the addition amount of blast furnace molten iron, scrap steel, returning charge and ferrosilicon manganese. According to the production practice research, the molten iron in the intermediate frequency furnace is 70%-80%, the addition amount of the return material is 10%-20%, the addition amount of scrap steel is about 10%-20%, and a small amount of ferrosilicon and Iron and ferromanganese (the actual addition of ferrosilicon is equal to the calculated addition minus the amount of si iron for inoculation). Temperature adjustment: According to the production research of machine tool castings, the intermediate frequency furnace only needs to heat the molten iron from 1250-1300 degrees when entering the furnace to 1450-1500 degrees, and the temperature rise is about 200 degrees. After a short time of overheating, ensure that the molten iron temperature is 1450-1500 degrees. The NKS series carbon-silicon analyzer and thermometer are used in front of the furnace to monitor the carbon content, silicon content, carbon equivalent, spheroidization rate and temperature in the raw molten iron online.
