Embodiment 1

[0040] Such as figure 2 As shown, the preparation method for preparing the above-mentioned metal composite plate comprises the following steps:

[0041] Step 101, pretreatment, the pure aluminum plate, 3003 aluminum alloy plate, 304 stainless steel plate and 430 stainless steel plate are subjected to surface grinding treatment, so that the surface is smooth and smooth;

[0042] Step 102, initial compounding, the pure aluminum plate and the 3003 aluminum alloy plate are rolled and compounded in the order of the 3003 aluminum alloy plate, the pure aluminum plate and the 3003 aluminum alloy plate to obtain a composite aluminum plate;

[0043] Step 103, initial annealing, annealing the composite aluminum plate in step 102 at a temperature of 550° C. for 25 minutes;

[0044] Step 104, secondary compounding, heating and rolling the 304 stainless steel plate and 430 stainless steel plate respectively on both sides of the composite aluminum plate to obtain a composite plate, and con...

Embodiment 2

[0049] The preparation method for preparing the above-mentioned metal composite plate comprises the following steps:

[0050] Different from Example 1,

[0051] In step 103, the annealing temperature is 600°C and the time is 24 minutes.

[0052] In step 104, the temperature of heating, rolling and pressing is 200° C., the pressure is 3000 KN, and the plate moving speed is 2.5 m / min.

[0053] In step 105, the annealing temperature is 400° C. and the time is 20 minutes.

[0054] The metal composite plate produced by the above steps can adapt to various cold processes such as deep drawing, stretching, bulging, bending, punching, edge dragging, etc. without delamination, so that the cooking utensils still maintain their original firm bonding state.

Embodiment 3

[0056] The preparation method for preparing the above-mentioned metal composite plate comprises the following steps:

[0057] Different from Example 1,

[0058] In step 103, the annealing temperature is 500°C and the time is 36 minutes.

[0059] In step 104, the temperature of heating, rolling and pressing is 300° C., the pressure is 2500 KN, and the moving speed of the plate is 4 m / min.

[0060] In step 105, the annealing temperature is 400° C. and the time is 20 minutes.

[0061] The metal composite plate produced by the above steps can adapt to various cold processes such as deep drawing, stretching, bulging, bending, punching, edge dragging, etc. without delamination, so that the cooking utensils still maintain their original firm bonding state.

Abstract

The invention relates to a five-layer metal composite material cookware. The five-layer metal composite material cookware comprises a cookware body and a handle arranged on the cookware body. The cookware body is formed by punching a five-layer metal composite plate, wherein the five-layer metal composite plate is formed by punching a 304 stainless steel layer with a thickness of 0.5-2 mm, a magnalium alloy layer with a thickness of 0.5-2 mm, a pure aluminum layer with a thickness of 0.5-2 mm, an aluminum alloy layer with a thickness of 0.5-2 mm, and a 430 stainless steel layer with a thickness of 0.5-2 mm. The five-layer metal composite material cookware has the advantage of being still capable of maintaining an original firm combination state due to the fact the metal composite plate is applicable to various cold machining processes such as deep drawing, stretching, expansion, hole punching and edge traction without layering; meanwhile, is light in weight, good and rapid in heat transfer, energy-saving and applicable to various cooking ranges.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a five-layer metal composite cooking utensil and a method for preparing the metal composite plate. Background technique [0002] Now the domestic production of cooking utensils (such as frying pans, etc.) material usually adopts a single material. Because a single material is limited by its inherent physical and chemical properties, the strength, hardness, wear resistance, corrosion resistance, heat transfer, electromagnetic induction performance and surface treatment process of the cooking utensil body material are greatly affected. Limitations, so that performances such as the internal and external comprehensive performance of cooking utensils made of a single material seem to be unsatisfactory. People have also proposed many improvement measures. For example, in order to make up for the lack of thermal conductivity of stainless steel, a piece of aluminum plate or co...
