Method and device for preparing metal composite pipe by interface fusion method

Abstract

The invention discloses a method and device for preparing a metal composite pipe through an interface fusion method. The device for preparing the metal composite pipe through the interface fusion method comprises a cylindrical heating pipe mold and a pouring pipe mold with the taper being 1000:1. The lower end of the heating pipe mold is connected with a steel wire brush wheel derusting machine. The bottom of a box body of the steel wire brush wheel derusting machine is connected with a guide hole in the top of the pouring pipe mold. The joint of the steel wire brush wheel derusting machine, the heating pipe mold and the guide hole of the pouring pipe mold is sealed through heat-resisting silica gel. According to the method and device for preparing the metal composite pipe through the interface fusion method, a pouring cavity is formed between a ceramic mold and a matrix pipe layer, and a high-frequency heater can be used for heating the matrix pipe layer; the ceramic mold has the heat storage function, heat losses of the matrix pipe layer can be reduced, and secondary refusion of a composite interface can be achieved; and the defect that a traditional metal mold is not suitable for high-temperature heating and temperature control is overcome.

Description

technical field [0001] The invention relates to a method and a device for preparing a metal composite pipe by an interface fusion method. Background technique [0002] Metal composite materials such as composite plates, composite pipes, and composite rods refer to composite materials formed by metallurgical bonding of various metals with different chemical and mechanical properties on the interface by using composite technology, which greatly improves the thermal expansion of a single metal material. , strength, fracture toughness, impact toughness, wear resistance, electrical properties, magnetic properties and many other properties, so it is widely used in anti-corrosion, pressure vessel manufacturing, power construction, petrochemical, pharmaceutical, light industry, automobile and other industries. Combining metals with excellent properties on the base layer or base tube layer can not only achieve the best overall performance of the material, but also save the amount of ...

AI Technical Summary

Problems solved by technology

The metal clad plate or metal clad pipe prepared by using the traditional production process has insufficient bonding force between the base plate or base tube layer and the composite plate or base tube layer, especially the composite layer on the base tube blank with a thinner tube wall. Not only is it difficult, the length of the composite pipe is limited, but it is also prone to damage during use, resulting in safety accidents
