Embodiment 1

[0018] The clad plate in this embodiment is a pipeline steel clad plate with a specification of 19*2580*14800 mm, wherein the base layer is steel type L415N pipeline steel with a thickness of 16 mm; the cladding layer is steel type 316L stainless steel with a thickness of 3 mm. Its heat treatment production method is:

[0019] 1. Weld a connection plate at both ends of the composite plate. The material of the connection plate is ordinary carbon and the length is 1m.

[0020] 2. Grind the welds and solder joints of the composite board until smooth and free of bumps, and remove oil, water and other harmful substances on the surface of the composite board.

[0021] 3. Place the cladding of the composite board upwards, close the upper head of the shot blasting machine, open the lower planer of the shot blasting machine, and perform shot blasting on the base layer of the composite board.

[0022] 4. Put the composite panel into the furnace for heating. When entering the furnace, p...

Abstract

The invention discloses a thermal treatment method for a composite board, and belongs to the technical field of thermal treatment. The thermal treatment production method comprises the following process steps: welding a connecting plate; polishing a welding joint and a welding spot; carrying out shot blasting treatment on the composite board; heating the composite board in a thermal treatment furnace; carrying out water-cooling on the composite board; re-reddening the composite board; cooling the composite board; cutting off a connecting plate; and the like. The thermal treatment method disclosed by the invention is utilized to produce a pipeline steel composite board with high performance and a high additional value, so that not only is limitation of enabling a direct rolling composite process to reach mechanical performance index supplemented, but also control on the plate shape of a steel plate in a thermal treatment process is sufficiently considered, and therefore, various performance indexes of a base layer and a coating reach standard requirements, and equipment operation safety is higher.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, in particular to a heat treatment production method of a composite plate. Especially for metal composite panels whose base material is pipeline steel and cladding material is stainless steel. Background technique [0002] The composite plate is composed of two parts, the base layer and the cladding layer. It means that one metal plate is covered with another metal plate. It is mainly combined by rolling composite or explosive welding. Compared with a single material, Bimetal composite panels have the best properties of the base and cladding materials at the same time, and can meet the performance requirements of high strength, high wear resistance, corrosion resistance, etc., which not only reduces the production cost, but also reduces the utilization rate of rare and precious metals Therefore, bimetal composite panels are increasingly used in machinery, construction, petroleum, chemical ...
