Roller furnace is a periodic resistance furnace, which is mainly used for gas carburizing, carbon nitrogen and polishing quenching heat treatment of bearing steel ball, roller and other small standard parts. It has the advantages of strong sealing performance, uniform furnace temperature, high thermal efficiency, low energy consumption and easy operation.

Indoor use: the ambient temperature is in the range of -5 to 40℃; The average monthly relative humidity in the use area is not more than 85%, and the average monthly temperature of the month is not higher than 30℃; There is no conductive dust, explosive gas and corrosive gas that can seriously damage metal and insulation around; No obvious vibration and turbulence.
