Embodiment 1

[0017] Manufacture a composite blank with a width of 1500mm×270mm×2500mm, and simultaneously roll two carbon steel-stainless steel clad plates with a thickness of 3mm and a double-layer stainless steel clad sheet with a thickness of 3mm with a rolling mill, and the base layer of the carbon steel-stainless steel clad plate The carbon steel plate adopts Q235 plate with a thickness of 2.5mm, the clad stainless steel plate adopts 304 stainless steel with a thickness of 0.5mm; , the thickness is 0.5mm; by calculating the thickness of the slab: the thickness of the base carbon steel plate is 75mm, a total of two; The six boards are assembled according to the structure shown in Figure 2, and the blanks are assembled in the way of using brazing material. After the blanks are assembled, the holes are drilled and heated to 400±10°C, and kept for 30 minutes, and the vacuum is kept at 1×10 -2 About Pa, then close the vacuum port, put it in a heating furnace and heat it to 900°C, and carry...

Embodiment 2

[0019] Manufacture a composite billet of width 1500mm×thickness 240mm×2500mm, and roll two carbon steel-stainless steel clad plates with a thickness of 2mm and a double-layer stainless steel clad plate with a thickness of 2mm at the same time with a coil rolling mill, wherein the base layer of the carbon steel-stainless steel clad plate The carbon steel plate adopts Q235 plate with a thickness of 1.5mm, the clad stainless steel plate adopts 304 stainless steel with a thickness of 0.5mm; , the thickness is 0.5mm; by calculating the thickness of the slab: the thickness of the base carbon steel plate is 60mm, a total of two; The six boards are assembled according to the structure shown in Figure 2, and the blanks are assembled in the way that no brazing material is used. After the blanks are assembled, the holes are drilled and heated to 400±10°C, and kept for 30 minutes, and the vacuum is kept at 1× 10 -3 About Pa, then close the vacuum port, put it in a heating furnace and hea...

Abstract

The invention discloses a method that adopts a compound compact and rolls three metal composite boards at the same time. The method comprises the following procedures: (1) the shape and the size of each layer of the metal board are identified according product requirements; (2) each surface that is to be recombined is cleaned: (3) assembly; (4) drilling vacuum pumping; (5) hot rolling and (6) finishing separation. When in assembly, a base metal plate, a multi-layer metal plate, high temperature anti-adhesive agent, a stainless steel plate, the stainless steel plate, the high temperature anti-adhesive agent, the multi-layer metal plate and the base metal plate are arranged in order. Under pressure, the surrounding of two base metal plates are welded with a separator to make space between two base metal plates sealed. The invention has the advantages of little investment and high production efficiency and is used for processing the metal composite plate.

Description

technical field [0001] The invention relates to the production technology of metal clad plates, more specifically, it relates to a method for simultaneously rolling three metal clad plates by using a clad billet. Background technique [0002] Chinese patent ZL200510033870.X (authorized announcement number CN100333844C, authorized announcement date: August 29, 2007) discloses a "method for producing brazed hot-rolled metal clad plates using composite billets", which provides a A new technical approach, but this method is usually used for the production and processing of composite plates with medium thickness. Although it can also process and produce thin plates made of carbon steel and stainless steel, this metal composite plate can reduce the cost of materials, but there are The above technical problem, that is, the welding problem in the processing of composite sheet is not conducive to the next cold rolling process. At present, the stainless steel plates on the market hav...
