Problems solved by technology

[0003] In the production process of double-sided composite panels, the usual method is: superimpose two single-sided composite panels and one double-sided composite panel, and after rolling, two single-sided composite panels and one double-sided composite panel are obtained after cutting. Double-sided composite panels, the double-sided composite panels obtained by this method have the following disadvantages: 1. The double-sided composite panels are wrapped in the middle of the base plate, and the double-sided panels are not in contact with the rolls during rolling, so the surface quality is difficult to guarantee, and sometimes even wrinkles appear. Affect product quality and the performance of subsequent products; 2. When forming a billet, it needs to be matched with two single-sided composite boards. The production organization is relatively difficult and the production efficiency is low.

Embodiment 1

[0049] Embodiment 1: as figure 1 , 2, 3, 4, 5, 6, 7, and 8 show a method for making a stainless steel double-sided composite panel, which includes the preparation of the primary blank and the preparation of the secondary blank in turn, and obtains 2 single-sided composite panels through the preparation of the primary blank. board, and then through the preparation of the secondary blank to obtain double-sided composite board outside the double board.

[0050] The making of one blank includes the following steps in turn:

[0051] (1) Selection of raw materials: select 2 base plates and 2 double plates, wherein the base plate is carbon steel, the double plate is stainless steel, stainless steel is selected as the double plate, and carbon steel is used as the base plate, expanding the use of the method obtained by the present invention. The scope of application of double-sided composite panels and the effect of use. The obtained double-sided composite board can be used as a pot...

Embodiment 2

[0078] Example 2: In the primary billet preparation process, step (3) when preparing the bar: select a carbon steel plate with a thickness of 14mm and cut it into a bar. Step (4) when preparing a rectangular frame: the distance between the outer edge of the bar and the edge of the substrate is 27mm; step (5) when applying a release agent: the first release agent, polyethanol aqueous solution and α-Al 2 o 3 The weight ratio of micropowder is 1:55; the weight ratio of the second release agent, polyethanol aqueous solution and white corundum micropowder is 1:55; Thereby thoroughly drying and removing free water in the release agent, thereby improving the use effect. Step (6) When preparing the assembled blank: a 4mm expansion gap 4 is provided between the doubler plate 2 and the retaining strip 5, so as to prevent the doubler plate from being thermally expanded and tightly attached to the rectangular frame. During the preparation of the primary billet and the preparation of the...

Embodiment 3

[0079] Example 3: In the primary billet preparation process, step (3) when preparing the bar: select a carbon steel plate with a thickness of 16mm, and cut it into a bar. Step (4) when preparing a rectangular frame: the distance between the outer edge of the bar and the edge of the substrate is 30mm; step (5) when applying a release agent: the first release agent, polyethanol aqueous solution and α-Al 2 o 3 The weight ratio of micropowder is 1:60; the weight ratio of the second release agent, polyethanol aqueous solution and white corundum micropowder is 1:60; Thereby thoroughly drying and removing free water in the release agent, thereby improving the use effect. Step (6) When preparing the assembled blank: an expansion gap 4 of 5mm is provided between the doubler plate 2 and the retaining strip 5, so as to prevent the doubler plate from being thermally expanded and tightly attached to the rectangular frame. During the preparation of the primary billet and the preparation o...

Abstract

The invention discloses a preparation method of a double-sided stainless steel composite board. The method comprises two steps of primary blank preparation and secondary blank preparation, wherein the primary blank preparation comprises the following steps: firstly selecting raw materials and manufacturing a rectangular frame; then overlaying the raw materials in the rectangular frame; and finally, press-fitting, welding, detecting leakage, vacuumizing and rolling so as to obtain a primary blank; and dividing the primary blank into two single-sided composite boards; the secondary blank preparation comprises the following steps: overlaying the two single-sided composite boards; welding, detecting leakage and vacuumizing; rolling; and finally treating after rolling to obtain the double-sided composite board with good surface performance. By virtue of the method disclosed by the invention, the base board and the composite board are rolled and the obtained double-sided composite board is high in surface quality and smooth and level in outer surface; the double-sided stainless steel composite board is simple to produce and easy to match; the product quality and the production efficiency are improved.

Description

technical field [0001] The invention belongs to the field of composite board production, and in particular relates to a method for manufacturing a stainless steel double-sided composite board. Background technique [0002] Double-sided composite panels, as a panel with excellent performance and energy saving, have been more and more widely used in the fields of construction and daily necessities. [0003] In the production process of double-sided composite panels, the usual method is: superimpose two single-sided composite panels and one double-sided composite panel, and after rolling, two single-sided composite panels and one double-sided composite panel are obtained after cutting. Double-sided composite panels, the double-sided composite panels obtained by this method have the following disadvantages: 1. The double-sided composite panels are wrapped in the middle of the base plate, and the double-sided panels are not in contact with the rolls during rolling, so the surface...
