Blast furnace copper cooling plate

Technical parameters:

Chemical composition: Cu99.97% 0 ≤ 30ppm H ≤ 1.0ppm

Mechanical properties: σ B ≥ 180MPa

δ≥ 35%

Copper steel bonding strength: σ B ≥ 200MPa

Brinell hardness HB ≥ 45

Physical properties: conductivity σ≥ 90% IACS

Water pressure and airtightness test: The water pressure is 1.5 times the working pressure, and the airtightness is 1.2 times the working pressure. Keep the pressure for 30 minutes and use a wooden hammer to strike without sweating or water leakage. Weld inspection standard: Conduct radiographic and ultrasonic color inspection on the welds and process hole welds between the cooling plate body and the steel ring of the blast furnace. The radiographic inspection standard reaches GB3323-87 Grade I-II, and the dye inspection standard reaches JB/T6062-92 Grade 2 or above.
