Problems solved by technology

[0012] 1. Each production must be matched with single-sided composite panels, and the proportion of double-sided panels is less than 42%. The production is not well organized, and it will inevitably cause a backlog of single-sided composite panels, and the finished product rate is less than 42%.
[0013] 2. If the cold-rolled base material is produced, one uncoiler and three coilers must be equipped at the same time, and the equipment investment is large and the floor area is large
[0014] 3. When used as a cold-rolled base material, since the hot-rolled compound is not directly rolled by the roll, there are defects on the surface, and the surface is difficult to reach the 2B standard during cold-rolled

Embodiment Construction

[0077] The production method of the stainless steel double-sided composite plate (coil) of the present invention is as follows:

[0078] 1. If figure 1 As shown, make a one-step rolling billet:

[0079] 1.1 Surface treatment of substrate and doubler board:

[0080] The material of base plate 1 is carbon steel, and the material of double plate 2 is stainless steel. The oxide layer and oil stains on the surface of base plate 1 and double plate 2 are cleaned by pickling, sand blasting, shot blasting, grinding, etc., so that Substrate 1 and doubler board 2 exhibit metallic luster.

[0081] 1.2 Prepare file 4:

[0082] Cut carbon steel (such as Q235B) with a thickness of 12~20mm into strips. The width of the cut strips is the sum of the thicknesses of the two doubler panels 1 plus 0.3~0.5mm, and clean the surface according to the method in step 1.1.

[0083] 1.3 Weld the bar 4 on one of the substrates 1 to form a rectangular frame. The distance from the outer edge of the recta...

Abstract

The invention discloses a production method for a stainless steel two-sided composite board, roll; the production method comprises the following steps: preparing one-step rolling blank: 1.1, processing the surfaces of a substrate and a composite board, the material of the substrate is carbon steel, the material of the composite board is stainless steel; 1.2, preparing file strip, cutting the carbon steel of 12-20mm on thickness into the strips, the width of the strips is the sum of the thickness of two composite boards with a plus of 0.3-0.5mm, and cleaning the surfaces of the strips according to the method in the step 1.1. The stainless steel and the carbon steel are combined together in a metallurgical bonding manner, the combination property of the material is improved; the product quality is superior to GB / T 8566-2008.

Description

technical field [0001] The invention relates to the field of production methods of composite plates, in particular to a production method of stainless steel composite plates and coils. Background technique [0002] Application of stainless steel double-sided composite panel (coil): [0003] 1) Because its thermal conductivity is much higher than that of pure stainless steel and it has magnetic conductivity, the pots used to make it can be used in electromagnetic [0004] Used on the furnace, it has fast heat conduction and saves energy. The pot made of it will replace the current double-bottomed pot. [0005] Curtain walls, keels, door and window materials and roof panels used in multi-storey buildings are replacement products of aluminum alloy and plastic steel; [0006] 2) The buckle plate of the elevator car; [0007] 3) Materials used for underwater and tidal range equipment in marine engineering; [0008] 4) Various liquid and chemical tank materials; [0009] 5) ...
