Furnace Rolls

n         Various of designs of rollers from dia.OD.50mm to OD.1600mm 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, etc.,

n        We offer custom engineering and production for assemblies and individual Components like machined tubes/barrel body,trunnions,shafts/journals,and refurbishment of existing rolls.

Application:

The various rolls/rollers are of good heat,corrosion,wear resistant properties,working at high temperature environment  on average: 800-1200°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.

Material:

High Nickel and high Chrome heat resistant alloys, Cobalt base alloys, like.
