Novel blanking column of hot charging type energy-saving airtight submerged arc furnace and manufacturing method thereof
Provided is a novel blanking column of a hot charging type energy-saving airtight submerged arc furnace. The novel blanking column is characterized by comprising a non-metallic blanking column body; the top of the non-metallic blanking column body is connected with a support connecting flange, and a heat-resisting metal reinforced grid is buried in the main body of the nonmetallic blanking column body. The novel blanking column has the characteristics of being resistant to oxidation and high temperature, long in service life, non-conducting, impermeable to magnetism and the like. The novel blanking column has the advantages of being small in thermal expansion coefficient, high in strength and hardness, resistant to erosion and oxidation, good in high-temperature chemical stability and the like, and meanwhile the non-metallic material is non-conducting, impermeable to magnetism, safe and reliable; certain difference exists between the linear expansion coefficient of the material of the heat-resisting metal reinforced grid and the linear expansion coefficient of the material of a cavity of the non-metallic blanking column body, and a high-temperature-resisting insulating coating separates the heat-resisting metal reinforced grid from the cavity of the non-metallic blanking column body so that heat stress generated by temperature variation can be reduced; meanwhile, the high-temperature-resisting insulating coating improves the insulating performance of the metal grid.
