 Application: 
 Department of the series resistance furnace cycle mode of operation for the laboratory, industrial and mining enterprises, scientific research units for elemental analysis and small size steel hardening, annealing and tempering heat treatment, heating, furnaces can be made of metal, ceramic sintering, dissolution of high-temperature heating. 


 Features: 
 1, the series resistance furnace shell is made of high-quality cold-rolled steel plate, the surface is treated by painting with the side door open structure, opening and closing flexible. 
 2, the temperature box furnace using closed to electric heating elements made of alloy wire spiral coil in the furnace after the walls among the heat when the temperature uniformity, to extend the service life. 
 3, high temperature tubular resistance furnace with high temperature combustion tube, silicon carbide heating elements, as installed in the furnace jacket. 
 4, high temperature resistance furnace Box-type silicon carbide heating element is installed directly in the furnace, heat utilization high. 
 5, the series resistance furnace insulation materials, lightweight foam insulation used 0.4-0.6 brick and aluminum silicate fiber cotton, to reduce the storage of heat and thermal conductivity, resulting in the furnace heat storage capacity, shortened heating time, the surface temperature is low, air furnace loss of power is small, power consumption is greatly reduced.
