Embodiment

[0023] Substrate blanking process:

[0024] The steel plate should have a quality certificate with clear marks; steel plates that require ultrasonic testing should pass the ultrasonic test as required; the steel grade, specification, and material inspection number of the material are consistent with the quality tracking card.

[0025] Mark the line according to the feeding specification and size of the quality tracking card. When marking the line, ensure that the included angle of the dimension lines on the four sides of the steel plate is a right angle. The deviation of the length and width of the steel plate is 0-5mm, and the deviation of the diagonal line is not more than 3mm.

[0026] Check the surface quality of the steel plate. If any quality defect is found on the surface of the steel plate, it should be processed in time to pass the qualification. Carry out gas cutting or shearing according to the scribed line, allow a proper amount of grinding allowance, clean the bu...

Abstract

The invention relates to an explosive cladding process of 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 NO6059 nickel-based alloy plates 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 NO6059 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] In the wet flue gas desulfurization absorption tower, due to the very harsh operating environment, general materials can no longer meet the anti-corrosion requirements. Although the corrosion problem of some parts of the absorption tower can be solved by lining rubber or glass flakes, it is not the absorption tower. This technology can be used in all places, so it is necessary to choose suitable special alloy materials to meet the requirements. [0003] NO6059 is a nickel-chromium-molybdenum alloy, the main component is 59Ni23Cr16Mo, its content of silicon and carbon is extremely low, it has excellent corrosion resistance, and has the following characteristics: it has excellent corrosion resistance to most corrosive media in the state of oxidation and reduction Corrosion resistance; excellent resistance to pitting corrosion, crevice corrosion and stress corro...
