Problems solved by technology

[0005] At present, there are many technologies for preparing stainless steel clad plates, and the technology is relatively widely used, but the production efficiency is generally low. Both the base plate and the clad plate have been rolled in advance, resulting in a sharp increase in cost after the secondary billet rolling. At the same time, the billet welding The workload is heavy, and the production efficiency of billet assembly is extremely low

Embodiment

[0033] see Figure 1-3 Shown, a kind of method that utilizes as-cast billet to prepare metal clad plate, comprises the following steps:

[0034] The first step is to cast the substrate blank 4 and the doubler blank 1 according to the designed shape according to the specifications of the blank assembly; the substrate blank 4 is a carbon steel ingot or alloy steel; the doubler blank 1 is a stainless steel ingot.

[0035] The thickness of substrate blank 4 is 60mm, the thickness of doubler blank 1 is 20mm, the thickness ratio of substrate blank 4 and doubler blank 1 is 3:1, and the length×width of substrate blank 4 and doubler blank 1=300mm×100mm.

[0036] In the second step, surface treatment is carried out on the cast base plate blank 4 and the doubler plate blank 1, and then the blanks are assembled; the surface treatment includes derusting treatment, surface passivation and chemical cleaning on the joint surface of the base plate blank 4 and the double plate blank 1 .

Abstract

The disclosure of the present invention provides a method for preparing a metal composite panel by using a cast blank. The metal composite panel includes cladding metal, base carbon steel or alloy steel, a binder and a mixed active adsorbent, and the cladding metal and The base metal is subjected to derusting treatment, passivation treatment, and chemical cleaning on the joint surface. Add adhesive to the joint surface of the substrate and double board, add mixed active adsorbent around the joint surface, and heat the joint surface twice before rolling to make the joint surface Air, water vapor, etc. are excluded or absorbed by the mixed active adsorbent, and the binder melts to seal the joint surface and avoid oxidation. What the present invention obtains is a method for compounding metal composite plates by using as-cast blanks, which can effectively solve the problems of long billet assembly cycle and high cost in conventional composite plate preparation methods, save vacuuming equipment, and reduce production costs.

Description

technical field [0001] The invention relates to the technical field of production and preparation methods of metal composite panels, in particular to a method for preparing metal composite panels from as-cast billets. Background technique [0002] Composite material is a new material obtained by forming two or more materials through a certain technology under specific conditions through a metallurgical reaction. This is a composite method to improve the comprehensive properties of a single material such as thermal expansion, fracture toughness, impact toughness, and electrical conductivity. [0003] The consumption of various resources in the current society continues to increase, and metal composite materials have the function of saving and reducing the use of scarce metals. The stainless steel composite plate retains the corrosion resistance, wear resistance and antimagnetic performance of stainless steel itself, and at the same time has the good weldability, formability ...
