Non-launder copper alloy converter with quick head changing traction device

Abstract

The invention discloses a non-launder copper alloy converter with a quick head changing traction device. A melting furnace and an insulation furnace are arranged to be in a form that furnace walls areconnected, the front portion is high and the back portion is low; a graphite releasing base containing a releasing hole and a releasing groove is arranged on the lower furnace wall of the melting furnace and the upper furnace wall of the insulation furnace; the melting furnace is connected behind the graphite releasing base; the insulation furnace is connected before the graphite releasing base;the flow of molten copper of the melting furnace is controlled by a first flow control rod; the quick head changing traction device consisting of a graphite control base, a graphite crystallizer, a crystallizer copper sleeve, a crystallizer steel cover and a cooling water cavity can sleeve the front end of the insulation furnace by a quick head changing hole; and the flow of molten copper of the insulation furnace is controlled by a second control rod. In the converter without a launder, the molten copper of the melting furnace nearly enters the insulation furnace directly without high heat and great volatilization of volatile metal; once towed wire blanks do not meet requirements, the traction can be immediately stopped to replace equipment, so that the staff and equipment safety is guaranteed; and the converter is safe, capable of saving energy, environmentally friendly and low in cost, and can improve the production efficiency of copper and copper alloy wire blanks.

Description

technical field [0001] The invention relates to the technical field of horizontal continuous casting of copper and copper alloys, in particular to a launderless copper alloy converter with a quick head-changing traction device for producing copper and copper alloy wire blanks. Background technique [0002] At present, the production method of copper and copper alloy wire billet is: "melting furnace → launder → holding furnace → horizontal continuous casting → wire billet" production process. The disadvantage of this production process is: copper water has a large amount of heat loss in the converter process of "melting furnace → launder → holding furnace", and also causes a large amount of volatilization of volatile metals, not only waste of raw materials and energy, but also It will seriously pollute the environment. In addition, the current horizontal continuous casting of copper and copper alloys uses multiple heads to draw copper alloys to improve production efficiency....

Problems solved by technology

The disadvantage of this production process is: copper water has a large amount of heat loss in the converter process of "melting furnace → launder → holding furnace", and also causes a large amount of volatilization of volatile metals, not only waste of raw materials and energy, but also will seriously pollute the environment

In addition, the current horizontal continuous casting of copper and copper alloys uses multiple heads to draw copper alloys to improve production efficiency. However, during the drawing process, if a wire billet fails and the product quality is unqualified, it cannot be replaced in time. The drawing casting can only be stopped below the casting line of the holding furnace for replacement

In this way, continuous production cannot be fully realized, which will affect production efficiency.
