Centrifugal casting heat resistant furnace roll  

Various of designs of rollers from OD 50 to 1,600mm for different applications, like furnace rollers before/after coating, charge discharge rollers, support roll, idler roll,guide roll, deflector roll, stabilizer roll, bridle roll, V-rolls, hearth roll, water cooling roll, quench roll, sink roll, working roll, drive roller, wet and dry rolls

• We offer custom engineering and production for assemblies and individual components like machined tubes/barrel body, trunnions, shafts/journals and refurbishment of existing rolls
• Applications:
• The various rolls/rollers are of good heat, corrosion, wear-resistant properties, working at high temperature environment on average: 800 to 1200°C, which are used in the steel mills, like CAL (continuous annealing line), CGL (continuous galvanizing line)
• Process:
• Centrifugal casting for barrel/tube, forging for journal/shaft, static /investment or sand casting for cone/trunions, welding and machining and grinding
• Materials Standards: ANSI, ASTM, ASME, DIN, GB
• High nickel and high chrome heat resistant alloys, cobalt base alloys, like HU, HT, HK, HP, HW, 24/24NbTiZr, 50Cr/50Ni (2.4813), 1.4865, 1.4849, 1.4848, 1.4410, 1.4059, 1.4841, 1.4845, 1.4852, 2.4879 or as per customer's requirements
