Processing process of copper tubes for two devices
1. Extrusion process
Explanation of copper tube extrusion process: The definition of extrusion process is that the copper embryo tube is extruded through a copper tube extruder, so that the density distribution of the copper tube is more uniform and the wall thickness is also evenly distributed, so as to achieve stronger compressive resistance.
2. Casting and rolling production process
Casting and rolling production process flow chart
Explanation of copper tube continuous casting and rolling process: The definition of continuous casting and rolling process is continuous casting and continuous rolling, so that the liquid copper burned at high temperature is poured into the continuous casting machine to roll out a copper billet (called continuous casting billet), which is not cooled later, but directly enters the hot rolling unit for rolling and forming after being kept warm in the soaking furnace for a certain period of time. The continuous casting and rolling process can skillfully combine the casting and rolling processes. Compared with the traditional process of first casting the copper billet and then heating it in a heating furnace and then rolling it, it has the advantages of simplifying the process, reducing labor, increasing metal yield, saving materials, enhancing the quality of the continuous casting billet, and producing energy-saving and environmentally friendly copper products, directly realizing the advantages of mechanization, programming and automation in one step.
