Embodiment

[0021] Substrate blanking process:

[0022] The steel plate should have a quality certificate with a clear mark; the steel plate whose material has ultrasonic testing requirements should be qualified by the ultrasonic testing according to the requirements; the steel number, specification, and material inspection number of the material should be consistent with the quality tracking card.

[0023] Mark the line according to the specifications and dimensions of the quality tracking card. When marking, ensure that the angle between the four sides of the steel plate is a right angle. The length and width deviation of the steel plate is 0-5mm, and the diagonal error is not more than 3mm.

[0024] Check the surface quality of the steel plate. If any defects on the surface of the steel plate are found, it should be processed in time. Carry out gas cutting or shearing according to the scribe line, allowing a proper amount of grinding allowance, clean the burrs after cutting, and remove the...

Abstract

The invention relates to an explosive cladding process for metals. The process is characterized by comprising the following steps: substrate treatment, composite treatment, applying and pairing, explosive cladding, repair welding, heat treatment and post-treatment. The process can help clad C276 nickel-based alloys with general steel plates effectively so that the clad steel plates can have the required strength on the premise of owning all the advantages of the C276 nickel-based alloys, thus saving consumption of expensive metals. The clad steel plates have high welding quality, and can certainly remain stable in long-term use without sealing off.

Description

Technical field [0001] The invention relates to a metal explosive compounding process. Background technique [0002] C276 alloy is a nickel-chromium-molybdenum alloy containing tungsten with extremely low silicon and carbon. It is generally regarded as a universal anti-corrosion alloy. The alloy has the following characteristics: ①It has excellent corrosion resistance to most corrosive media in both oxidation and reduction atmospheres. ②It has excellent resistance to pitting, crevice corrosion and stress cracking corrosion. C276 alloy is suitable for various chemical industries containing oxidation and reduction media. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C276 alloy is one of the only materials resistant to corrosion by humid chlorine, hypochlorite and chlorine dioxide solutions. It has significant corrosion resistance to high-concent...
