Box type resistance furnace | High temperature resistance furnace

Box-type resistance furnace
The series resistance furnace cycle mode of operation for the laboratory , industrial and mining enterprises , scientific research institutes, universities for elemental analysis and small size steel hardening, annealing, tempering and other heat treatment, heating , high temperature furnace can be made of metal, ceramic high temperature sintering , dissolution and analysis heating.
Product Features :
1, the shell is made of high-quality cold-rolled steel , spray the surface treatment process, door with side door structure , closed Kai flexible.
2, using a closed furnace to an electric heating element alloy wire is made into a spiral , coiled on the furnace walls among the heat when the temperature uniformity extended service life.
3 , lightweight foam insulation material selection, as well as aluminum silicate fiber cotton insulation bricks to build heat and thermal conductivity reduce furnace heat storage capacity resulting in shorter heating time , the surface temperature is low, the small air furnace loss rate , power consumption is greatly reduced .
4, using intelligent digital temperature controller .
