Technological process for producing brass pipe through upwards continuous casting, continuous rolling and drawing

Abstract

The invention provides a technological process for producing brass pipes. The flow of the technological process comprises the following steps of: melting electrolytic copper or red impure copper and metallic zinc ingots or copper-zinc alloy brass complex materials through a melting furnace; fusing to generate copper-zinc alloy melts; enabling the copper-zinc alloy melts to enter a heat preserving furnace through a channel for heat preservation; then crystallizing through a crystallizer and cooling; carrying out upwards continuous casting to produce brass pipe blanks through a hauling machine; and subsequently rolling and drawing the brass pipe blanks into finished pipes. Compared with the traditional technological process, the technological process adopted in the invnetion simplifies a plurality of complex processes, i.e. melting, round copper billet casting, scaling, punching, heating, extruding and drawing, into the processes of upwards continuous casting, continuous rolling and the drawing, thereby greatly simplifying the process flow; and in addition, the technological process has the advantages of simple process, high finished product ratio, low energy consumption, little metal loss, almost no pollution and low labor intensity of workers and production cost and is the simplest and most efficient processing technology of technological processes for producing the brass pipes at present.

Description

Technical field [0001] The invention relates to a process method for producing brass tubes, in particular to a process method for up-drawing continuous casting, continuous rolling and stretching to produce brass tubes. Background technique [0002] Since it was invented and promoted in the last century, the upward continuous casting technology has been widely promoted and applied. It is the leader in the metal field and has been driving the revolution and innovation of human casting and rolling technology. Since the development of the oxygen-free copper pipe technology of my country's upward continuous casting in the 1990s, the technology and cost control of oxygen-free copper pipes by my country’s copper pipe manufacturers have been perfect. [0003] While the copper tube technology is continuously improving, the brass tube up-drawing technology has also attracted widespread attention from various manufacturers and scientific research institutions, but so far, only 4 units produce...

Problems solved by technology

[0003] While the copper tube technology continues to improve, the brass tube upward lead technology has also attracted widespread attention from various production enterprises and scientific research institutions, but so far, there are only 4 sets produced by the Beijing No. 2 Copper Tube Factory in the 1990s The upper drawing machine produced samples, but due to the technical immaturity and the material characteristics of the brass tube itself, it could not be promoted and applied in production, and the brass tube upper drawing still remained at the stage of theoretical approval.
