Heat Resistant Roll
Various designs of rollers from Ø 50 to 1, 600mm for different application, 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
1. Application:
The various rolls/rollers are of good heat, corrosion, wear resistant properties, working at high temperature environment on average: 800 to 1, 200° C, which are used in the steel mills, like CAL (continuous annealing line), CGL(continuous galvanizing line)
2. Process: Centrifugal casting for barrel/tube, forging for journal/shaft, static /investment or sand casting for cone/trunions, welding and machining and grinding
3. Material: 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
4. Standard: ANSI, ASTM, ASME, DIN, GB
5. Quality control: We have in-house facility for each inspection, composition by spectrometer; Size test, mechanical test, NDT, UT, RT, PT, MT, ET
6. Certificates: ISO9001: 2008; 3.1B Material Certificates, SGS Certificate.
