Furnace bottom roll because of its production have different caliber, also because of its furnace temperature ranging from 850 degrees to 850 degrees Celsius, the material of its use is also different.Furnace bottom roll in metallurgical industry usage is very big, is essential to steel smelting production process and processing equipment.Furnace bottom roll made from small diameter of 60 mm - 1600 mm Φ Φ various national standard material of heat-resisting alloy steel hollow bottom roller. Furnace temperature ranging from 850 ℃ to 1200 ℃, the use of material is also different. Suitable for general tubes, pipe, stainless steel pipe annealing treatment, etc. Especially made requires higher reliability of continuous annealing processing line with large diameter furnace bottom roll.
