Abstract

The invention relates to an anti-radiation ODS steel-steel composite plate and a preparation method. The anti-radiation ODS steel-steel composite plate comprises a base layer steel and an ODS steel composite layer compounded on a base layer in a rolling manner, the contact surfaces of composite materials and a base material are polished, the non-polished surfaces of the two composite materials arecoated with a separant and dried, the composite materials and the base material are stacked in sequence to form composite blanks, the assembled composite blanks are conveyed to a vacuum chamber, gapsbetween the composite blanks are welded through vacuum electron beams, and the blanks are conveyed to a heating furnace to be heated, rolled, tailed-out, straightened, cooled, cut and divided into plates. The anti-radiation ODS steel composite plate with good metallurgical bonding effectively solves the problem of online process anti-radiation performance of the base material ODS steel in the composite plate, the process is simple, and the rolling success rate is high.

Description

technical field [0001] The invention relates to the technical field of metal composite material manufacturing, in particular to a radiation-resistant ODS steel-steel composite plate and a preparation method. Background technique [0002] With the sharp increase in demand in the domestic energy market and the rapid development of industries such as petrochemicals, power plants, and nuclear power plants, a large amount of radiation-resistant metal materials are required. Due to the large-scale equipment, users have put forward higher requirements for the corrosion resistance and radiation resistance of the equipment and the service life. Therefore, the metal steel used for manufacturing equipment can no longer meet the requirements of users. The Cr, Mo and Ni content is higher High radiation-resistant ODS steel is suitable for harsh environments with strong radiation. [0003] In general, there are two production methods for stainless steel clad plates: explosion method and r...
