Document Type and Number:
WIPO Patent Application WO/2021/208332
Kind Code:
A1
Abstract:
The present invention provides a manufacturing method for a three-layer metal clad steel plate, comprising the following specific steps: measuring the magnetic content; performing slab milling and polishing pretreatment on composite blank steel plates; daubing an adhesive and stacking and bonding the composite blank steel plates; completing welding and sealing of the clad steel plate by means of spot welding in combination with vacuum pumping welding; heating the welded clad steel plate in three stages of low-temperature heating, medium-temperature heating and high-temperature heating by a soaking pit furnace; removing an oxide skin on the surface of the discharged clad steel plate by means of a phosphorus removal box, and then respectively performing rough rolling and finish rolling; straightening the rolled clad steel plate; and stacking the delivered clad steel plate for slow cooling, and performing flaw detection. The method provided in the present invention can manufacture high-performance and high value-added clad steel plates without environmental pollution, is high in safety coefficient, and is a green and environment-friendly process.
