Embodiment 1
[0025] Industrial scale production of ultra-low carbon Cr-Ni-Mo5923hMo alloy steel / common low alloy steel Q345B explosive welding high corrosion resistance composite material, the production method is:
[0026] 1. Pretreatment process before explosion: 1. Grinding and polishing the bonding interface with grinding wheel and cloth wheel to remove the oxide layer on the surface to achieve the purpose of flatness, lightness and cleanliness. 2. Determination of the size of base, doubler board and drug distribution; the doubler board is 40mm longer than the four sides of the base plate, and the size of the drug distribution is the same as that of the doubler board. 3. Before installing the base and double boards, wash the two joint surfaces with acetone to remove dust and oil stains on the surface.
[0027] 2. Explosive welding composite process: select powdered ammonium oil emulsion explosive with low detonation velocity, and add powdered industrial salt accounting for 25% of the t...

[0031] Industrial scale production of ultra-low carbon Cr-Ni-Mo5923hMo alloy steel explosion welding high corrosion resistance composite material, the production method is as follows:
[0032] 1. Pretreatment process before explosion: 1. Grinding and polishing the bonding interface with grinding wheel and cloth wheel to remove the oxide layer on the surface to achieve the purpose of flatness, lightness and cleanliness. 2. Determination of the size of the base, compound board and drug distribution; the compound board is 20mm longer than the four sides of the base plate, and the drug distribution size is the same as that of the compound board. 3. Before installing the base and double board, wash the two joint surfaces with acetone to remove dust and oil stains on the surface.
[0033] 2. Explosive welding complex process: select powdered ammonium oil emulsion explosive with low detonation velocity, and add powdered industrial salt accounting for 30% of the total mass, 3-4% perli...
