Abstract

The invention discloses a hot forging and molding process for oxygen free copper materials. The hot forging and molding process is different from the traditional cold extrusion process in prior art. According to this process, a hot forging method is adopted to process the oxygen free copper materials and process parameters including a preheating temperature of moulds, a heating temperature of materials, and a lubrication oil component are ensured. The hot forging and molding process can be used to prepare precise oxygen free copper components which are smooth on surface, good in performance, and qualified in combustion. The process steps are simple to operate and applicable to industrialization promotion, the finished product rate is high, and all the parameters of products are excellent.

Description

technical field

[0001] The invention relates to the field of chemical industry, in particular to a hot forging process for oxygen-free copper material products. Background technique

[0002] Oxygen-free copper means that the oxygen content is not more than 0.003% (mass fraction), and the total impurity content is not more than 0.03% (mass fraction, No. 1 oxygen-free copper TU1) or not more than 0.05% (mass fraction, No. 2 oxygen-free copper TU2) Pure copper, the purity of copper is greater than 99.95%. Oxygen-free copper has no hydrogen embrittlement, high electrical conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance.

[0003] Due to the characteristics of oxygen-free copper, in addition to the high requirements for the raw materials for processing and producing oxygen-free copper, it is also required that impurities and oxygen should not be brought in during the production and processing of oxygen-free coppe...
