Problems solved by technology

The metal clad plate or metal clad pipe prepared by the traditional production process has insufficient bonding force between the base plate or tube layer and the clad layer, especially when the clad layer is applied to the base tube blank with a thinner tube wall, it is not only difficult, but the composite The length of the tube is limited, and it is easy to be damaged during use, resulting in safety accidents

Embodiment 1-1

[0047] A method for preparing a metal composite panel by an interface fusion method adopts the following steps:

[0048] (1) Surface treatment:

[0049] The base slab is 2205 duplex stainless steel plate with a thickness of 10mm. The oxide and grease on the surface of the base slab are removed by acid solution, the rust on the surface of the base slab is removed by mechanical friction with a wire brush, and then the surface of the base slab is wiped clean with acetone ;

[0050] (2) placing the base slab flat on a support base, keeping the clean upper surface of the base slab horizontal;

[0051] (3) According to the thickness of the composite alloy layer, place four plate-shaped ceramic molds vertically on the four sides of the top of the base slab, and seal the joint of the plate-shaped ceramic mold with aluminum silicate rock wool containing self-flowing refractory mud to make the plate A cuboid pouring cavity is formed between the ceramic mold and the base slab;

[0052...

Embodiment 1-2

[0062] The difference between this embodiment and embodiment 1-1 is:

[0063] The thickness ratio of the base slab to the alloy layer is more than 10:1, and if there are obvious pits on the surface of the base slab in step (1), use a lathe to remove the surface until it is smooth and bright; The temperature is 30°C higher than the melting point of the alloy metal liquid and the melting point of the base slab. Before pouring the alloy metal liquid, a high-frequency heater is used to move from one end above the base slab to the other end to heat the surface of the base slab. Make the temperature of the surface of the base slab reach the range of 20°C close to the melting point of the base slab, and keep the moving speed of the high-frequency heater consistent with the moving speed when the alloy metal liquid is poured.

[0064] By repeating the operations of steps (1)-step (9), another alloy layer can be compounded on the basis of the composite slab to obtain a metal composite p...

Embodiment 1-3

[0066] The difference between this embodiment and embodiment 1-1 is that: the thickness ratio of the base slab to the alloy layer is 1:1-1:10; if there are obvious pits on the surface of the base slab in step (1), Not adopted; the temperature of the alloy metal liquid in step (5) is 30° C. higher than the melting point of the alloy metal liquid and the melting point of the base slab.

Abstract

The invention discloses a method for preparing a metal composite plate and a metal composite pipe through an interface fusion method. The method for preparing the metal composite plate and the metal composite pipe through the interface fusion method comprises the steps of surface treatment, pouring cavity preparing, alloy metal liquid pouring and the like. A pouring cavity is formed between a ceramic mold and a matrix pipe layer or matrix plate layer, and a high-frequency heater can be used for heating the matrix pipe layer or matrix plate layer; the ceramic mold has the heat storage function, heat losses of the matrix pipe layer or matrix plate 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 for preparing a metal composite plate and 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...
