Problems solved by technology

Because the explosion process will generate jets, which will self-clean the surface of the base cladding plate, so that the fresh metal will be combined, but when the plate width is too large, there will be more and more jet materials, and the jet materials cannot be completely removed after reaching both ends, and part of the jets will be eliminated. Confined in the bonding area, resulting in poor bonding strength or even non-fitting at both ends

Abstract

The invention discloses an explosive welding method for manufacturing a composite plate from a C-276 alloy. According to the explosive welding method, a steel plate and a C-276 alloy plate are included. The explosive welding method of the composite plate comprises the following steps of (1) making preparation for the steel plate and the C-276 alloy plate subjected to grinding and primary treatmentbefore explosion; (2) selecting a plurality of satisfactory conventional supporting blocks and a plurality of satisfactory auxiliary supporting blocks; (3) selecting powder emulsion explosive as mainexplosive; (4) arranging the C-276 alloy plate on the auxiliary supporting blocks; (5) arranging and fastening a detonator at the center of the C-276 alloy plate; and (6) detecting the attachment ratio and the shear strength. According to the explosive welding method, the C-276 alloy / steel composite plate is produced with the explosive as energy through explosive cladding so as to realize nationalization, and the requirements for development of the chemical engineering industry and other industries in China are met.

Description

technical field [0001] The invention relates to the technical field of composite plates, in particular to an explosive welding method for making composite plates by using C-276 alloy. Background technique [0002] C-276 alloy is a nickel-molybdenum-chromium-tungsten nickel-based alloy, which is the most corrosion-resistant of modern metal materials. It is mainly resistant to wet chlorine, various oxidizing chloride solutions, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low temperature and medium temperature hydrochloric acid. Therefore, in recent years, the application in petrochemical industry, salt production, environmental protection engineering and flue gas desulfurization has gradually increased. This material mainly depends on imports, and the price is very high. Therefore, under the premise of ensuring that the service life and performance of the equipment are not reduced, the C-276 alloy-steel composite plate is u...
