Problems solved by technology

Another development direction is continuous extrusion production. Since the melting point of zinc in copper-zinc alloys is much lower than that of copper, it is still impossible to solve the problem of zinc precipitation in the extrusion process. pickling problem

Embodiment Construction

[0015] A processing technique for zinc brass, characterized in that: said technique comprises the following steps:

[0016] a) Stretching: Stretch the zinc brass with a drawing die, cool the zinc brass, refine the crystal grain on the surface of the brass billet, and fix the core of the zinc brass at the same time;

[0017] b) Planing: Use a planer to plan the zinc brass to remove the crystal lines on its surface;

[0018] c) Continuous drawing: use a drawing machine to carry out multi-mode continuous drawing of zinc brass, and pull the wire diameter of zinc brass from 8.0mm to 2.2~3.0mm;

[0019] d) Annealing: Three-stage annealing in the preheating section, heating section, and cooling section, and DC voltage for annealing;

[0020] e) Winding: Straighten the zinc brass and then wind it.

[0021] In steps b and c, the emulsion is sprayed on the drawing die for lubrication. Specifically, emulsion lubrication is used instead of butter lubrication. The emulsion is sprayed on...

Abstract

The invention discloses a zinc brass machining technology. The technology comprises the steps of stretching, peeling, continuous-drawing, annealing, rolling and the like. The machining technology hasthe following advantages that 1, acid washing is not needed, so that the influence on the environment is reduced, and the production cost and the damage to workers are reduced; 2, and annealing is carried out by using online direct-current voltage to replace original oxidation annealing, copper loss in oxidation annealing can be reduced, and maximum utilization of copper resources can be realized;and 3, the labor productivity is effectively improved due to the fact that original multi-pass repeated drawing is replaced by using high-speed continuous-drawing and continuous-annealing and brass large-machining-rate technology, so that the practical significance is realized, and the original production and machining modes of the whole industry can be changed.

Description

technical field [0001] The invention relates to the technical field of copper production, in particular to a process for processing zinc brass. Background technique [0002] During the development of brass wire processing, the initial processing equipment basically used steel processing equipment for production, and the drawing process was processed in a single pass, and oxidation annealing was used between each pass to solve the internal structure of the billet after drawing recrystallization problem. The processing equipment is horizontal drawing machine or triple continuous drawing equipment often used in steel processing, and the mechanical noise is large. The mold lubrication is all lubricated by butter, which has relatively large oil fumes during use and serious environmental pollution. At the same time, the labor intensity of workers is relatively high and the production efficiency is low. After annealing, it needs to be pickled before it can be processed again. T...
