Water cooling furnace roller in continuous annealing line
Description
The tension roller and work roll 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. Materials: 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.
