An induction heating channel and tundish beneficial for removing inclusions in molten steel

Abstract

The invention discloses an induction heating channel and a tundish beneficial for removing inclusions in molten steel, comprising a shroud, an injection chamber, an induction heating channel, an inner channel, an air blowing port, an induction coil and an iron core, a pouring chamber and an immersion type Nozzle, a long nozzle is provided at the center of the top of the injection chamber, an induction heating channel is provided on one side of the injection chamber, an inner channel is provided at the bottom of the end of the induction heating channel far away from the injection chamber, and the end of the inner channel far away from the induction heating channel is connected to the pouring chamber. The bottom of the pouring chamber is symmetrically provided with submerged nozzles; the bottom of the induction heating channel is provided with a blowing port, and the inner side of the induction heating channel is surrounded by induction coils and iron cores. Beneficial effects: simple and compact structure, reasonable design, small footprint, relatively convenient layout and maintenance, the newly designed heating channel has a return section, which prolongs the residence time of molten steel in the channel and increases the floating of inclusions in molten steel in the pipeline probability.

Description

technical field [0001] The invention relates to the technical field of steelmaking and continuous casting equipment, in particular to an induction heating channel and a tundish which are beneficial for removing inclusions in molten steel. Background technique [0002] In the steelmaking and continuous casting production process, the tundish is an important metallurgical reaction vessel, which plays an important role in continuous casting, decompression, diversion, protection and removal of inclusions. However, in the steelmaking process, the molten steel will have a certain heat loss when passing through the tundish, and the temperature will fluctuate, so that the quality of the billet cannot be guaranteed to a certain extent. On the other hand, the tundish is the final link to remove inclusions before the molten steel solidifies. Although the flow of molten steel in the tundish can be optimized to promote the floating of inclusions, it is easy to generate slag and have a g...
