Embodiment 1

[0028] (1) 10g of brazing flux is mixed with 1.5g of iron powder with a purity greater than 99.9%, and 0.3g of inorganic silica gel is added to increase the viscosity to obtain solder;

[0029] (2) Using the above-mentioned solder, bond the aluminum foam material with a size of 100mm×100mm×20mm to the aluminum plate with a size of 100mm×100mm×30mm;

[0030] (3) Use induction heating outside the plate, the heating frequency is 2000Hz, heat the brazing flux to 625°C for 20min;

[0031] (4) Rapid cooling, using forced water cooling, the water cooling speed is 120°C / min, and the brazing forming is completed.

[0032] The brazing flux is composed of the following chemical components in mass percentage: Al 14.5%, Cu 3.2%, Mg 1.8%, Y0.25%, V 0.15%, and the balance is Zn.

Embodiment 2

[0034] Replace the iron powder in Example 1 with an equivalent amount of iron-nickel-based material, and the rest are the same as Example 1.

[0035] The iron-nickel-based material is composed of the following chemical components in mass percentage: Ni 34.8%, Al 3.2%, Mn 0.45%, Ti 0.36%, and the balance is Fe.

Embodiment 3

[0037] Step (1) in Example 1 is replaced by "mixing 10g brazing flux, 1.5g iron-based material with a purity greater than 99.9% and 0.015g antimony powder, and adding 0.3g inorganic silica gel to increase the viscosity to obtain solder", All the other are with embodiment 1.

Abstract

The invention discloses a rapid brazing composite process based on induction heating of iron-based materials, and relates to the field of brazing technology. The brazing performance of the brazing material is optimized by adding iron-based materials, and inorganic silica gel is added to increase the viscosity. In this way, the fast brazing composite of foamed aluminum material and aluminum plate can be realized, and the brazing quality can be guaranteed at the same time; It is suitable for military industry, aerospace, ships and other application fields that require high performance and stability of composite panels.

Description

Technical field: [0001] The invention relates to the technical field of brazing, in particular to a rapid brazing composite process based on induction heating of iron-based materials. Background technique: [0002] Foamed aluminum is a new type of aluminum-based metal material that is made by adding additives to pure aluminum or aluminum alloy through foaming or other processes, and has the characteristics of metal and bubbles. It has low density, high temperature resistance, corrosion resistance, and sound insulation. It has the characteristics of low noise, low thermal conductivity, strong impact absorption ability, strong fire resistance, and strong weather resistance. [0003] Brazing refers to a welding method in which the solder below the melting point of the weldment and the weldment are heated to the melting temperature of the solder at the same time, and then the gaps in the solid workpiece are filled with liquid solder to connect the metals. Brazing material, also...
