The box-resistance furnaces used in clement determination and heating in heat treatment of steel, such as hardening, annealing and tempering of laboratories, industrial mining enterprise, scientific research unit and colleges. The high temperature muffle furnace could be used in high temperature heating of metal, sintering, dissolution and analysis of ceramic.
Characteristics:
1. The box-resistance furnaces adopt the cold rolling steel spraying exterior. Lifting and horizontal moving type door ensure the inner temperature evenness and no leakage under the high temperature.
2. PID controller or Programmable controller as requirement. Controller has the function of timing and over-temperature protection.
3. Medium temperature box adopts enclosed firepot. The spiral electric alloy wire coil as heating component coiled on the furnace walls. It is efficient and durable.
4. High-temperature tubular furnace adopts high temperature proof combustion tube, and takes Silicon Carbide Rod as heating component to fix on the firepot exterior.
5. High-temperature box-resistance furnace takes Silicon Carbide Rod as heating component to fix inside the firepot.
6. The heat preservation material adopts 0.4-0.6 light cellular heat insulator stick and alumina silica cell cotton, it has lower thermal storage and heat conductivity factor, large thermal storage in firepot, heating fast, the furnace surface temperature is low and high effective.
