Preparation method of metal clad plate

Abstract

The invention discloses a preparation method of a metal clad plate. The method includes the following steps of firstly, preparing a covering plate layer, wherein two covering layers including a stainless steel plate layer and a titanium plate layer are combined through a hot mill in a rolling mode to prepare the titanium-stainless steel covering plate layer; secondly, combining a covering plate with a base plate, wherein the covering plate, the base plate and a polymer coating are overlapped and then rolled three times through a rolling device to be combined into a metal composite plate; thirdly, conducting a quenched-tempered heat treatment and forming process on the metal composite plate to prepare the product. The preparation method is simple in process and high in controllability.

Description

technical field [0001] The invention relates to the technical field of metal composite materials, in particular to a method for preparing a metal composite plate. Background technique [0002] At present, most of the metal composite materials that have achieved metallurgical bonding in China are produced by rolling cladding and explosive cladding. The thickness of the cladding of the rolled cladding is about 1mm, and the total thickness is about 3mm; the thickness of the cladding of the explosive cladding is greater than 2mm. There are very few composite materials with a total thickness of more than 6mm and a cladding of less than 2mm on the market, mainly because it is difficult to produce or the cost is too high by conventional methods. The rolling composite method can produce metal composite materials with a cladding layer of less than 2mm, but generally the total thickness does not exceed 3mm. To produce composite panels with a thickness of 6 to 8mm, the initial investme...

There are very few composite materials with a total thickness greater than 6mm and a cladding of less than 2mm on the market, mainly because it is difficult to produce or the cost is too high by conventional methods

The rolling composite method can produce metal composite materials with a cladding layer of less than 2mm, but generally the total thickness does not exceed 3mm. To produce composite panels with a thickness of 6 to 8mm, the initial investment in equipment is very large; the explosive composite method can produce composite materials with a total thickness greater than 6mm , but the minimum coating thickness can only reach 2mm
