In recent years, aluminum tubes have been widely used in all fields of social life. As we all know, China is very dynamic in the world, and it is a big steel consumption market. Although there is a great demand for steel in China, the profit of the steel industry is gradually decreasing, there is still demand, and there is no profit.

The aluminum tube extruder currently used includes an extrusion box and a cylinder.

The heated aluminum block is put into the extrusion box from the supply port, so that the cylinder works and the extrusion beam moves the aluminum block to the extrusion die. Even if the aluminum block at high temperature has good plasticity, even if the temperature of the aluminum block drops, the plasticity will drop, and the extrusion pad will drop during the extrusion process at a certain pressure and speed of the extrusion beam. The aluminum block is in a strong pressure state in the extrusion deformation area, so that it can give full play to its plasticity and obtain a large deformation amount. At the same time, extrusion deformation can improve the microstructure and mechanical properties of metal materials, especially for extruded products, whose mechanical properties can be quenched by other processing methods.

Therefore, it is necessary to improve this situation. Seamless aluminum pipe generally adopts the method of piercing extrusion. Seamless aluminum pipe has the characteristics of small specific gravity, easy processing and high mechanical strength, so in fact, the production process of seamless aluminum pipe requires stricter and finer requirements. However, several problems must be paid attention to in producing seamless aluminum tubes with qualified quality. The problems that should be paid attention to in the production process of seamless aluminum pipe and the successful practical experience are given

Large seamless aluminum tubes are generally formed by hot extrusion, which is effectively treated. Seamless aluminum pipe can be hot extruded or cold drawn, and can also be effectively treated after subsequent treatment.

In order to prevent the seamless aluminum pipe from frosting, the extruded round aluminum alloy rod itself must have no rolling cracks. Please do not store it in a humid environment. The content of sodium hydroxide in the cleaning solution is about 30%, so please strictly control the content of aluminum ions in the cleaning solution.
