Reasons for Cracking of Furnace Shell of Automobile Annealing Furnace of Dryer

The steel structure of the trolley annealing furnace mainly includes the furnace shell support frame and the drive equipment support frame (platform steel structure). Taking into account the potential thermal expansion and cold shrinkage of the furnace shell, the supporting frame of each section of the furnace shell and the platform steel structure are independent of each other. First install the bottom roll chamber of each furnace section in place, and complete the welding of the four reference columns according to the four corner columns. The left and right integral end plates are welded again. The operation side and the transmission side are welded and installed from bottom to top by several independently manufactured side plates. The top roller chamber of the then mounted top roller chamber also has 4 reference posts. The trolley annealing furnace shell can be manufactured and installed by positioning, installing and welding from the quasi-column and the furnace body 4 . Several widened platforms are installed on the drive side for the storage of the stove top cover.

Dryer has good temperature tracking performance

High-temperature resistance furnaces use high-quality resistance wires, silicon carbide rods or silicon molybdenum rods (depending on the customer's high temperature requirements) as heating elements. Depending on the heating element, the blast furnace temperature of the high temperature resistance furnace can reach 1200°C, 1400°C and 1700°C, respectively, and the thermocouple indices are K, S and B, respectively. The high temperature resistance furnace can prepare 30 heating curves for heating, the temperature control accuracy can reach +/- 1°C, the heating speed can reach the high operating temperature within 30-60 minutes, the high heating speed can reach 40°C/min, and the recommended temperature is 20°C /min High temperature resistance furnace equipment runs automatically and has good temperature tracking performance. High temperature resistance furnaces are widely used in the research of metal materials, ceramics, glass, etc.
