Description

technical field [0001] The invention belongs to the technical field of bimetal composite plates, and in particular relates to a stainless steel composite plate for railway equipment. Background technique [0002] Generally, stainless steel clad plates are produced by explosion method and rolling method. The explosion method is not a sustainable composite panel preparation technology due to its high noise, pollution to the environment, and greater influence by the weather. The rolling method uses high-temperature rolling to achieve a good metallurgical bond between the composite material and the base material by using the diffusion between atoms. The composite plate produced by it can be flexibly adjusted in width, which is a green and sustainable production process. . Therefore, the production of composite panels by rolling will be the trend of future development. Contents of the invention [0003] The technical problem to be solved by the present invention is to overco...
