Excellent quality gas annealing furnace for metal heat treatment
Description
Excellent quality gas annealing furnace for metal heat treatment is used to do heat treatment for the workpieces that weights 1-100t .The application of high speed burners is especially suitable for technological process that needs high requirements of temperature uniformity, such as annealing, tempering or soft quenching,and powerful air circulation system can effectively ensure to reach the best temperature uniformity within the effective range .Matching with the main equipements ,a variety of sensors and electrical control equipments are equipped to ensure that the bogie hearth furnace can be applied to all kinds of crafts.
Main features
1. Adopt natural gas as heat source, improving the economy of the operation, and realizing environmental protection and energy saving, etc.
2. Adopting intelligent combustion controller.
3. The refractory fiber is ceramic fiber block, with good heat preservation effect, fast temperature rising, it can save energy by 20% - 30% compared with brick lining.
4. If it is damaged by mechanical collision, it only needs local modification, repairing, replacement, and can be put into application after repaired without heating the empty furnace.
5. Good noise reduction function
6. Seismic resistance performance is good.
7. Electrical control part is purchased from domestic famous brands, if they cannot meet your requirements, we can also supply you international famous brands, such as schneider, omron, and Siemens, etc.
