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 is mainly suitable for common tubes, pipe and stainless steel pipe annealing treatment.If using a higher request and more reliability of continuous annealing processing line to use large diameter of the furnace bottom roll.Furnace bottom roll industry development in our country and the research has a history of for many years, so far has made great progress and development, the performance of the furnace bottom roll is also got a boost.For knowledge and understanding of the furnace bottom roller we should work harder, so you can better use the furnace bottom roll for our services, and the use of appropriate method can prolong the service life of the furnace bottom roll.Regular maintenance can make the furnace bottom roll better longer for us to make great contributions to the metallurgy.
