1、Extrusion process
Explanation of the extrusion process of copper pipe: the definition of the extrusion process is that the copper embryo tube is extruded and molded by the copper pipe extruder, so as to make the density distribution of the copper pipe more uniform, the wall thickness is also distributed at the same time very well proportioned, so as to achieve a stronger resistance to compression capacity performance.
2、Casting and rolling production process
Continuous casting and rolling process is defined as continuous casting continuous rolling, so that the high temperature sintered liquid copper poured into the continuous casting machine rolled out of copper billet (known as continuous casting billet), the subsequent not after cooling, directly in the even heat furnace insulation for a certain period of time directly into the hot rolling unit in the rolling molding of copper rolling process. Continuous casting and rolling process it can cleverly casting and rolling two process combination of the use of up, and before the traditional first casting of copper billets after heating furnace heating and then rolling process has abbreviated process, reduce labor, increase the rate of metal harvesting, saving materials, enhance the quality of continuous casting billets, the production of energy-saving and environmentally friendly copper products, a step to achieve a direct mechanization, programming and automation of the advantages.
3、Copper tube on the lead method process flow
On the lead method of continuous casting of copper tube of the original characteristics of the "oxygen-free", that is, the oxygen content of 10ppm or less, electrolytic copper melted at high temperatures into a copper liquid conversion, hardening and molding of the entire process, the use of charcoal reduction and scaled graphite cover, oxygen isolation and other process techniques. Oxygen in the molten copper liquid is a new type of copper oxide and cuprous oxide exists, charcoal in the role of high temperature, can be deoxygenated by itself, so that its oxygen content of less than 10 ppm. in the process of the chemical reaction produced by the CO protective gas and scale graphite oxygen barrier, graphite is no longer oxidized in the process of crystallization, so as to achieve the effect of the above cited process.
