Embodiment Construction

[0026] Such as figure 1 As shown in FIG. 2 , the structure of a common cooker for a variety of stoves with a three-layer composite board includes a cooker body composed of a cooker body 1 and a cooker bottom 2 connected thereto. The cooker body 1 of the cooker body is a three-layer composite metal plate whose middle layer is 409 or 430 stainless steel, and the inner and outer layers are aluminum alloy. It is a two-layer composite metal plate of aluminum alloy.

[0027] The method for making the above-mentioned general-purpose cooker for various stoves with three-layer composite boards comprises the following steps:

[0028] First, first select a three-layer composite metal plate with the middle layer of 409 or 430 stainless steel and the inner and outer layers of aluminum alloy, that is, the layer arrangement of the three-layer composite metal plate is aluminum alloy outer layer 5+ middle stainless steel layer 3+ aluminum alloy Alloy inner layer 4, its concrete level is:

Abstract

The invention discloses a three layered composite plate cooker with wide application and its production method. The cooker comprises cooker body having body part and bottom part. The body part contains stainless steel 409 or 430 intermediate layer, and aluminum alloy inner and outer layers. The bottom part contains stainless steel 409 or 430 bottom layer and aluminum alloy inner layer. The method comprises selecting plate materials with stainless steel 409 or 430 intermediate layer and aluminum alloy inner and outer layers, drawing and forming the cooker body having body part and bottom part, surface-treating (oxidizing, spray-coating, etc.), and polishing to remove aluminum alloy outer layer on bottom and expose the stainless layer. The cooker has firm inter-layer bonding and wide application.

Description

technical field [0001] The invention relates to a cooking utensil, in particular to a cooking utensil made of a three-layer composite board which is common to various stoves and a manufacturing method thereof. Background technique [0002] At present, except that the cooking utensils on the domestic and foreign markets have the cooking utensils that magnetic material is made, all the other cooking utensils are compounded with a magnetic conductive metal sheet at the bottom in order to enable them to be used on the induction cooker and other stoves. Although such cooking utensils can be used on induction cookers and other stoves, the double-bottom metal sheet and the cooker are two kinds of metals after all, and their coefficients of thermal expansion and contraction are different. Composite life and firmness are very limited, and there are many falling off and delamination phenomena during use, which will bring many changes to the use of cookware, and even lose the use funct...
