Abstract
The invention discloses a stainless steel clad plate and a manufacturing method thereof. The stainless steel clad plate comprises stainless steel on the surface, a middle polymer composite coating and a base plate at the bottom layer. The manufacturing method of the stainless steel clad plate adopts a hot-press combination technology, and the stainless steel clad plate is manufactured by continuously compounding the stainless steel and the base plate by a hot-press combination unit. The pressure, the temperatures of press rolls and the linear velocities of an upper roll and a lower roll of the hot-press combination unit can be synchronously controlled. After the method is adopted, the stainless steel clad plates with different specifications can be produced by a common hot-press roller machine. The stainless steel clad plate prepared by the method is simple in technology and free from pollution, thus being suitable for large-scale continuous production.
