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 invention provides a method for preparing a metal composite plate by using as-cast blanks. The metal composite plate comprises a multi-layer metal, base-layer carbon steel or alloy steel, a bonding agent and a mixed activated adsorbing agent, wherein the bonding surfaces of the multi-layer metal and the base-layer metal are subjected to rust removal, passivation and chemical cleaning, the bonding agent is added to the bonding surfaces of the base plate and the compound plate, the mixed adsorbing agent is added to the peripheries of the bonding surfaces, before rolling, heating is conductedtwo times under atmosphere protection, so that air, water vapor and the like on the bonding surfaces are removed or adsorbed by the mixed activated adsorbing agent, the bonding agent is melted to make the bonding surfaces sealed, and oxidation is avoided. The method for preparing the metal composite plate by using the as-cast blanks can effectively solve the problems that a conventional preparation method for the compound plate is long in assembling period, high in cost and the like, a vacuum extraction equipment is omitted, and the production cost is reduced.

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 ...
