Split type insulation intermediate tank induction heater

Abstract

The invention provides a split type insulation intermediate tank induction heater. The split type insulation intermediate tank induction heater can effectively solve the problems that according to existing intermediate tank induction heating equipment, heating can be caused by interaction vortexes generated by an intermediate tank and peripheral equipment during work, and consequently the efficiency is low, and the using power is limited; and electromagnetic force is made to break through a critical point for extruding non-metallic inclusions, and the practical effect of refining molten steelis achieved. The split type insulation intermediate tank induction heater is composed of two parts including the split type insulation intermediate tank and a split insulation induction heater body, the split type insulation intermediate tank is composed of an intermediate tank split steel shell and an intermediate tank sub-cavity refractory body, the intermediate tank sub-cavity refractory body is composed of a molten steel impact cavity, a heater protection refractory body and a molten steel casting cavity, and the heater protection refractory body is internally provided with a heating channel and is used for communicating the molten steel casting cavity and the molten steel casting cavity; and meanwhile, a heater coil installing hole is formed, the split insulation induction heater bodyis composed of an upper iron core, a lower iron core and an initial coil, and all components are fixedly connected with the intermediate tank split steel shell, and an insulation structure is arranged.

Description

technical field [0001] The invention relates to the technical field of continuous casting in the steelmaking industry, in particular to a tundish, in particular to a split-type insulated tundish induction heater. Background technique [0002] In recent years, with the continuous improvement of steel billet quality requirements in the steelmaking industry, higher requirements have been put forward for maintaining a stable temperature of molten steel in the tundish continuous casting and improving the purity of molten steel in the tundish, while the existing Tundish heating equipment does not have the function of refining molten steel to improve its purity, and there are various disadvantages that affect its popularization and practicality: for example, plasma heating technology has the disadvantages of high noise, low heating efficiency, need for atmosphere control, and high cost of use. There are induction heaters applied to the tundish, because while inductively heating the...
