Embodiment 1

[0036] like figure 2 Shown, the preparation method of preparing above-mentioned composite board comprises the following steps:

[0037] Step 101, pretreatment, the pure aluminum plate, magnesium 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;

[0038] Step 102, initial compounding, rolling and compounding the pure aluminum plate and the magnesium-aluminum alloy plate to obtain a composite aluminum plate;

[0039] Step 103, primary annealing, annealing the composite aluminum plate in step 102 at a temperature of 550° C. for 30 minutes;

[0040] Step 104, secondary compounding, heating and rolling the 304 stainless steel plate and the 430 stainless steel plate respectively on both sides of the composite aluminum plate to obtain a composite plate, wherein the 430 stainless steel plate and the pure aluminum plate are rolled Pressing and laminating, the 304 stainl...

Embodiment 2

[0045] The preparation method for preparing the above-mentioned composite board comprises the following steps:

[0046] Different from Example 1,

[0047] In step 103, the annealing temperature is 600°C and the time is 2.5 hours.

[0048] In step 104, the temperature of heating, rolling and pressing is 200° C., the pressure is 2500 KN, and the plate moving speed is 2.5 m / min.

[0049] In step 105, the annealing temperature is 600°C and the time is 2 hours.

[0050] The 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

[0052] The preparation method for preparing the above-mentioned composite board comprises the following steps:

[0053] Different from Example 1,

[0054] In step 103, the annealing temperature is 500° C. and the time is 30 minutes.

[0055] In step 104, the temperature of heating, rolling and pressing is 400° C., the pressure is 2500 KN, and the moving speed of the plate is 3 m / min.

[0056] In step 105, the annealing temperature is 400° C. and the time is 30 minutes.

[0057] The 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 multi-layer cooking appliance containing magnalium, which comprises a cooking appliance body and a handle arranged on the cooking appliance body, wherein the cooking appliance body is formed by sequentially stamping a plurality of metal composite boards, namely a 304 stainless steel layer with the thickness of 0.5-2mm, a magnalium layer with the thickness of 0.5-2mm, a pure aluminum layer with the thickness of 0.5-2mm, and a 430 stainless steel layer with the thickness of 0.5-2mm from inside to outside. The multi-layer cooking appliance has the benefits that the composite board can adapt to various cold processing such as deep drawing, stretching, bulging, bending, punching and hauling, without layering, so that the cooking appliance can still keep the original firm bonding state; and the cooking appliance is light in mass and rapid in heat transfer, has good heat transfer property, saves energy, and is suitable for various different cooking ranges.

Description

technical field [0001] The invention relates to the technical field of cooking utensil materials, in particular to a multilayer cooking utensil containing magnesium and aluminum alloys and a preparation method for a composite plate thereof. 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 st...
