Manufacturing method for stainless steel composite boards

The invention discloses a manufacturing method for stainless steel composite boards and belongs to the technical field of manufacturing processes of metal composite boards. The manufacturing method includes the following technical steps that (1), base metal and a stainless steel composite layer which are the same in length and width are selected, a surface to be compounded is machined and washed, and a circumferential chamfering groove is formed; (2), the base metal and the stainless steel composite layer are aligned at and stacked to the surface to be compounded, and front blanks are welded on the periphery; (3), the surfaces of stainless steel composite layers of the two front blanks are machined, cleaned and stacked oppositely, the two stainless steel composite layers are welded together after a parting agent is brushed between the two layers, and a composite pack rolling blank is obtained; (4), the composite pack rolling blank is heated and rolled; (5), thermal treatment and other treatments are carried out on the stainless steel composite boards. The manufacturing method overcomes the defects that a blank machining process is complex, vacuum equipment is required, and the high vacuum degree is difficult to obtain and control in an existing manufacturing method for the stainless steel composite boards. The manufacturing method for the stainless steel composite boards is simple in process, short in period, high in efficiency and low in cost.
