Chinese patent ZL 200510033870.X (authorized announcement number CN100333844C, authorized announcement date: August 29, 2007) discloses a "method for producing brazed hot-rolled metal composite plates using composite billets", which provides However, this method is usually used in the production and processing of clad plates with medium thickness. Although it can also process and produce thin plates clad with carbon steel and stainless steel. Although this metal clad plate can reduce the cost of materials, 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
And this kind of double-layer stainless steel composite thin plate, there is no relevant product sales in the current domestic and foreign markets, and there is no relevant technical report

Embodiment 1

[0028] Referring to Figure 1 and Figure 3, a double-layer stainless steel composite thin plate with a width of 1219mm and a thickness of 3mm is manufactured. The thickness of the base stainless steel plate is 2.5mm, and the back of the clad stainless steel plate is 0.5mm. The base stainless steel plate is 201 stainless steel with a size of 1219×2440×225mm Plate 1, 1219×2440×45mm 304 stainless steel plate 2 is used for the multi-layer stainless steel plate. According to the method of forming blanks without brazing materials, the surfaces of the two stainless steel plates are cleaned and then welded and sealed on the 500T press platform. Then drill the hole and heat it to 400±10°C, keep it warm for 30 minutes, and keep vacuuming at 1×10 -3 About Pa, then close the vacuum port, put it in a heating furnace and heat it to 1150°C, and then roll it in an 8000T stainless steel continuous rolling mill and roll it up. The width of the double-layer stainless steel clad plate is 1219mm, th...

Embodiment 2

[0030] Referring to Figure 2 and Figure 3, a double-layer stainless steel composite thin plate with a width of 1500mm and a thickness of 3mm is manufactured, in which the thickness of the base stainless steel plate is 2.5mm, and the back of the clad stainless steel plate is 0.5mm. Plate 1, 304 stainless steel plate 2 of 1500×2500×45mm is selected as the multi-layer stainless steel plate. According to the blank formation method using brazing material, the thickness of the brazing material layer 3 is 10 microns. After cleaning the surfaces of the two stainless steel plates Weld and seal the blanks on the 500T press platform, then drill holes and heat to 400±10°C, keep it warm for 30 minutes, and keep vacuuming at 1×10 -2 About Pa, then close the vacuum port, put it into a heating furnace and heat it to 900°C, and then hot-roll it in a medium-sized stainless steel continuous rolling mill, and roll it into a double-layer stainless steel clad plate with a width of 1500mm and a thick...

Embodiment 3

[0032] Manufacture a double-layer stainless steel composite thin plate with a width of 1500mm and a thickness of 3mm. The thickness of the base stainless steel plate is 2.5mm, and the thickness of the clad stainless steel plate is 0.5mm. 2500×45mm 304L stainless steel plate, according to the preform assembly method using brazing material, the thickness of the brazing material is 1 micron, clean the surface of the two stainless steel plates, weld and seal the preform on the 500T press platform, and then drill and heat To 400±10°C, keep warm for 30 minutes, keep vacuuming at 1×10 -2 About Pa, then close the vacuum port, put it into a heating furnace and heat it to 1000°C, then hot-roll it in a medium-sized stainless steel continuous rolling mill, and roll it into a double-layer stainless steel clad plate with a width of 1500mm and a thickness of 3mm about 225m.

Abstract

The invention discloses a double-layer stainless steel composite sheet and a processing method thereof, and belongs to the technical field of a metal composite sheet. The sheet is formed by compounding two corrosion resistant plates of different materials through hot rolling. The processing method comprises the following steps: firstly, the physical dimensions of the two corrosion resistant plates are determined according to the product requirement; secondly, the surfaces of the two corrosion resistant plates to be compounded are cleared up; thirdly, the surfaces of the two corrosion resistant plates to be compounded are arranged oppositely before the surfaces are superposed; the peripheral hems of the joint faces of the two corrosion resistant plates are welded and sealed under pressure; fourthly, the corrosion resistance plates are drilled and vacuumized; fifthly, the vacuumized compounded preform is hot rolled and moulded in the temperature of 900 DEG C to 1150 DEG C on a roll before the preform is coiled. The product disclosed by the invention has the advantages of excellent processability and low use cost.

Description

technical field [0001] The invention relates to a metal composite plate, more specifically, it relates to a double-layer stainless steel composite thin plate, and the invention also relates to a processing method of the composite thin plate. Background technique [0002] The application of metal composite panels or composite coils is mainly based on economy and the purpose of saving natural resources, as well as special uses on various equipment. Chinese patent ZL 200510033870.X (authorized announcement number CN100333844C, authorized announcement date: August 29, 2007) discloses a "method for producing brazed hot-rolled metal composite plates using composite billets", which provides However, this method is usually used for the production and processing of medium-thickness clad plates.
