Process for bonding stainless steel and carbon steel composite plate

Abstract

This invention relates to a bonding process of non-corrosive steel carbon steel sandwich, which comprises the following steps: a) acid cleaning and derusting the carbon steel plate, surface cleaning the non-corrosive steel at the same time; b) bushing high-intensity adhesive on the surface of carbon steel plate or non-corrosive steel, and sticking them together; c) extruding the adhered non-corrosive steel and carbon steel plate, making them stick to sandwich; d) extruding the sandwich with planisher, and then cleaning excess adhesive dirt; e) forming roll bending type with rolling machine ,or forming plate type with guillotine.

Description

technical field [0001] The invention relates to the technical field of metal reprocessing, in particular to a processing method for combining two metal plates into one. Background technique [0002] At present, stainless steel and carbon steel composite panels are used for the metal shell, exterior decoration, guardrail pipes, and anti-theft doors and windows of the products. The advantage of this kind of composite plate is not only that the price is much cheaper than that of pure stainless steel plate, but also on the basis of retaining the beautiful appearance of stainless steel plate, it increases the strength and expands the scope of use. [0003] There are currently only two production methods for stainless steel and carbon steel composite panels. The first method is the rolling method adopted by Yanghai Special Steel Co., Ltd., Zhuhai City, Guangdong Province: First, cut a 0.5 mm thick stainless steel plate into a small plate, coat a layer of medium with graphite as t...

AI Technical Summary

Problems solved by technology

The disadvantage is that the hot rolling process deforms the stainless steel plate, and multiple follow-up processing processes such as cold rolling, pickling graphite medium, and polishing are required. Pinhole, the thinnest can only compound 0.07 mm thick stainless steel plate

The disadvantages are that the stainless steel plate has large deformation, needs to be re-polished, pollutes the environment, is prone to safety accidents, and has few product specifications. It can only be composited with a stainless steel plate with a thickness of about 2 mm, which cannot meet the multi-specification requirements of users.
