Abstract

The invention provides an erosion-resistant CAS-OB refining device for a dipping cover. The service life of the dipping cover can be prolonged, the production cost is reduced, and the refining efficiency is improved. The erosion-resistant CAS-OB refining device for the dipping cover provided by the invention comprises a dipping cover, a dipping cover lifting device, an oxygen lance, an alloy material chute, slag, a steel ladle and perforated bricks, and is characterized by also comprising a motor, a transmission shaft, a gear and a concave-convex connection buckle, wherein the upper part of the dipping cover is a fixed part, and the lower part of the dipping cover is a rotating part, and the two parts are connected by virtue of the concave-convex connection buckle. According to the erosion-resistant CAS-OB refining device provided by the invention, the structure of the CAS-OB dipping cover is changed, the asymmetric erosion degree of the dipping cover is alleviated, the utilization rate and operation rate of equipment are improved, the refining cycle is shortened, and the aim of prolonging the service life of the dipping cover is achieved.

Description

technical field [0001] The invention belongs to the technical field of refining outside the furnace in the metallurgical industry, and relates to a CAS-OB refining device, in particular to a CAS-OB refining device with an erosion-resistant dipping cover. Background technique [0002] CAS (Composition Adjustment by Sealed Argon Bubbling) refining technology is a simple out-of-furnace refining process developed by Yawata Technology Research Institute of Nippon Steel Corporation in 1975. It has been gradually refined since the late 1980s. Promote apps. The CAS-OB refining process is developed on the basis of the CAS refining process. [0003] The CAS process is to blow argon gas at the bottom of the high-strength ladle to form a slag-free area on the surface of the molten steel above the argon blowing hole. The CAS dipping cover is inserted into the slag-free area of ​​the molten steel to make the inside of the cover closed. An inert atmosphere is formed above the liquid. Th...
