The invention discloses a medium-frequency induction furnace smelting high-speed steel dephosphorization technology and facility. An outer-layer reaction furnace is included, a heating plate is fixedly installed on the inner wall of the outer-layer reaction furnace, a top box is welded and fixed to the upper end of the outer-layer reaction furnace, and a second hydraulic telescopic rod is fixedlyinstalled on the inner wall of the middle of the upper end of the top box; a power box is welded and fixed to the lower end of the second hydraulic telescopic rod, a reinforcing ring is welded and fixed to the lower end of the power box, a connecting rod is placed in the reinforcing ring, a mounting plate is welded and fixed to the lower end of the connecting rod, and an inner-layer reaction furnace is fixedly mounted in the heating plate; and a discharging port is formed in the lower end of the inner-layer reaction furnace, and a box door is mounted at the upper end of the inner-layer reaction furnace. The medium-frequency induction furnace smelting high-speed steel dephosphorization facility is simple in structure and convenient to operate, a dephosphorization agent can be evenly added into smelted steel, dephosphorization work on the steel is completed, and the medium-frequency induction furnace smelting high-speed steel dephosphorization facility is worthy of application and popularization.
Description
technical field [0001] The invention relates to the technical field of metal smelting, in particular to a dephosphorization technology and equipment for smelting high-speed steel in an intermediate frequency induction furnace. Background technique [0002] The intermediate frequency induction furnace is a green short-process smelting equipment for comprehensive utilization of scrap steel resources with high efficiency, low energy consumption, and low emissions. However, because it does not have the thermodynamic and kinetic conditions for phosphorus removal, it greatly limits the expansion of smelting varieties. [0003] Phosphorus is easy to segregate at the grain boundaries of steel and cause cold embrittlement of steel, which can significantly reduce the low temperature impact performance of steel. Therefore, it is regarded as a harmful component in most steel grades. How to reduce phosphorus to the limit at low cost has always been the direction of steelworkers' efforts...
