The company continues to absorb domestic and foreign advanced technology and scientific management experience, improve the competitiveness in the domestic market, the factory has a welding operation base, equipped with a variety of welding machine, blanking, coil plate, plate shearing, press and other equipment 45 sets. The main equipment is 32× 8000mm plate rolling machine, 3× 6m and 4× 15m CNC cutting machine, 16mm× 2m large plate machine, 500 tons press, submerged arc welding machine, CO2 gas shielded welding machine, 600× 500× 2000mmH steel welding equipment. The factory has decades of practical experience in various kinds of large roller, large mixer, large kiln mill, large machine room, large sintering machine skeleton and air box, as well as various structural parts. All the professional staff have passed the training and examination after holding the certificate, and some also have the internationally recognized senior qualification certificate. The coarse roughness of the steel can reach 12.5, and the construction is equipped with good preheating means, which can effectively weld for various materials and welding rods. The qualified rate of the first inspection of the junction members welded by CO2 gas shielded welding, multiple gas shielded welding and submerged arc welding is more than 90%. In order to eliminate the residual thermal stress of welds and prevent future deformation, all welds are treated for stress removal by heat treatment or mechanical vibration before machining, and the measured residual stress curve can be provided.
