High temperature large chamber lab muffle furnace

This series of electric furnaces is intermittent operation furnaces which can be used in normalizing, annealing, quenching, tempering, hardening and other heat treatments of carbon steel, alloy steel, high-speed steel and other metal parts. Organic liquid can be dripped into cracking atmosphere of the furnace to realize little-oxidizing heating. 

Characteristics of chamber furnace :

1.Adopt mixed furnace lining of ultra-light refractory bricks (0.6/cubic meter) and ceramic fiber, greatly shortening starting heating time and extraordinarily saving energy up to 20%-30%.

2. Specially-designed furnace door and roller sealing, and built-in heating wire ensure excellent furnace door sealing and uniform furnace temperature.

3. Double-thermocouple control: one thermocouple is for testing furnace temperature, and the other one is for over-heat protection.

4. The furnace is equipped with interlock protection device, which can prevent Failure and accident due to misoperation.

5. Adopt intelligent digital temperature-control system, which feature clear reading, conveniently adjusted, high temperature control precision, easy structure, safe and reliable.

 Applicable for normalizing and quenching of metal parts: light refractory brick and refractory fiber are used as furnace lining to ensure excellent sealing and extraordinary energy saving. For heat treatment of high-grade alloy steels and metal sintering and melting heating

 For heating, aging and tempering of moulds and steel parts in petrochemical industry, medical service and laboratory.
Feature: siliceous alumious fiber cotton is pressed on insulating layer and furnace bottom and the whole set of device has no refractory brick. It features fast temperature rise and excellent heat preservation.

For quenching, anealing, tempering and other heat treatments of chemical analysis and research of R&D institutions and industrial and mining enterprises, etc.
