Embodiment approach

[0022] Substrate blanking process:

[0023] The steel plate should have a quality certificate with clear signs; the steel plate whose material has ultrasonic testing requirements should pass the ultrasonic testing according to the requirements; the steel number, specification, and material inspection number of the material are consistent with the process card.

[0024] Mark the line according to the blanking specification and size of the process card. When marking the line, ensure that the included angle of 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 5mm.

[0025] 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 line, allow an appropriate amount of grinding allowance, remove bur...

Abstract

The invention discloses an explosive welding method of an SAF2507 composite steel plate. The method comprises the following steps of: leveling to enable the flatness of the steel plate to be less than 3mm / m; treating the composite material to ensure that the plate flatness of the SAF2507 alloy is less than 5mm / m; brushing and pairing: brushing the composite material protective agent on the SAF2507 alloy plate, and paring with the steel plate; and explosively compositing: placing the steel plate flatly on the explosive table, and arranging the SAF2507 alloy plate on the steel plate in parallel, arranging a V shaped support between the steel plate and the SAF2507 alloy plate, uniformly arranging the explosive on the outer surface of the SAF2507 alloy plate, detonating the explosive via the detonator, and tightly bonding the surface of the SAF2507 alloy plate and that of the steel plate together under the high brake pressure. The invention provides an SAF2507 super-duplex stainless steel plate with the higher quality and wider application range.

Description

technical field [0001] The invention relates to a metal explosive composite process, which belongs to the field of metal composite plate manufacturing. Background technique [0002] SAF2507 alloy is a super-duplex stainless steel composed of 25% chromium, 4% molybdenum and 7% nickel. It has strong strength and corrosion resistance and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. The higher chromium, molybdenum and nickel content makes it have high resistance to pitting, cracking and general corrosion, but the price is more expensive. So it is necessary to combine SAF2507 with common metal. SAF2507 super-duplex stainless steel clad steel plate is used in oil and gas industry equipment, offshore platforms, heat exchangers, underwater equipment, fire fighting equipment, chemical processing industry, vessel and pipeline industry, subma...
