Automatic gas blowing rod for liquid bottom deflective blowing

Abstract

The invention discloses an automatic gas blowing rod for liquid bottom deflective blowing. According to the automatic gas blowing rod for liquid bottom deflective blowing, a stainless steel bolt, a steel sleeve and a ceramic base are arranged in sequence from inside to outside; an upper fastening nut is arranged at the upper end of the automatic gas blowing rod for liquid bottom deflective blowing; a lower fastening nut is arranged at the lower end of the automatic gas blowing rod for liquid bottom deflective blowing; a limiting base which is in abutting fit with the lower fastening nut is arranged at the lower end of the automatic gas blowing rod for liquid bottom deflective blowing; a steel jacket and a ceramic base are both in abutting fit with the upper end of the limiting base; a cross rod used for fixing the automatic gas blowing rod for liquid bottom deflective blowing is arranged at the upper end of the automatic gas blowing rod for liquid bottom deflective blowing; a driving device fixedly arranged to the other end of the cross rod is arranged at the other end of the cross rod; and the driving device not only can drive the cross rod to move up and down in a reciprocating manner but also can enable the cross rod to move around the driving device for 360 degrees. The invention aims at providing the automatic gas blowing rod for liquid bottom deflective blowing, which hasthe advantages that the gas blowing rod is automatically controlled to have a molten steel equalizing effect, the structure is simple, small space is occupied, the working efficiency can be enhanced,and manpower and material resources can be saved.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to an automatic air blowing rod used for partial liquid bottom blowing. Background technique [0002] Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio between elements to obtain the best performance. [0003] Put the pig iron into the steelmaking furnace and smelt it according to a certain device to get steel. Steel products include steel ingots, continuous casting slabs and direct casting into various steel castings. Generally speaking, steel generally refers to steel rolled into various steel products. [0004] The air blowing device is a method of sending oxygen and hydrogen into the furnace to remove harmful elements such as C and S in the furnace. [0005] General ordinary air blowing device ne...

AI Technical Summary

Problems solved by technology

[0005] Ordinary air blowing devices need to be artificially sent into the furnace body, so the human body is close to the furnace body, which is prone to danger, and the height of the air blowing device is generally higher than that of a person and its weight is heavy, which is inconvenient for human operation
