Continuous Annealing Furnace Roll
Furnace roll are the most important parts of the continuous annealing furnace.
The roll/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)
The function of furnace rolls is to make the annealing furnace run efficiently. Its working condition is the decisive factor if annealing hearth furnace can be normal production. They are often used in metallurgical industry, steel industry, food industry, etc.
