Aluminum carbon bale roughing slag controller used for continuous casting

Abstract

The invention discloses an aluminum carbon bale roughing slag controller used for continuous casting, belonging to a fireproof material used for continuous casting. A control block (1) and a screw (2) are connected by an inner wire iron nut (1.3) on the control block (1) and a thread on the screw (2); the bottom of the control block (1) is provided with four same support frames (1.1); the screw (2) is provided with an upper connecting mechanism (2.1) and a lower connecting mechanism (2.2); and the controller is fixed in the bale by the upper connecting mechanism (2.1) and the lower connecting mechanism (2.2) of the screw (2). The control block (1) is manufactured by adopting aluminum carbon materials at certain proportion; the integral height is larger than the height of the traditional bale liquid level, which is about to generate vortex; and the area of the cross section is bigger than the area of a bale steel tapping hole so as to effectively prevent from generating the vortex and prevent slag floating on the bale molten metal surface from being rolled into a tundish to guarantee the casting blank quality. Meanwhile, the support frame (1.1) is high enough to ensure that the molten metal normally flows out of the steel ladle, and the molten metal is poured into the tundish to ensure that the continuous casting process is normally carried out.

Description

technical field [0001] The invention belongs to refractory materials for continuous casting, and mainly relates to a slag lowering controller for aluminum-carbon ladles for continuous casting. Background technique [0002] Large ladle, also known as ladle, ladle, ladle, is the necessary equipment for continuous casting of molten steel. In order to maintain the temperature of molten steel in the ladle, it is necessary to add carbonized rice husk or insulation material on the surface of molten steel to reduce heat loss. In addition, in order to achieve the purpose of refining outside the furnace, it is also necessary to add metallurgical auxiliary materials such as synthetic slag. At the end of pouring, when the ladle liquid level drops to a certain height, it is easy to form a vortex at the ladle outlet, and the above-mentioned slag will be involved in the tundish, thereby affecting the quality of the cast slab. Contents of the invention [0003] The object of the present ...
