Batch Furnace
In a batch furnace single load is heat treated at a
time. Batch-type furnace is essential for large parts such as heavy
forgings and are preferred for complex alloy grades which requires long
cycles. Batch furnaces are available in various size and configurations.
They are heated either through gas or through fuel. How it works? In batch furnaces same door is used to load and unload the part. In these furnaces one batch at a time can be produced. A load after being purged with nitrogen is moved into the brazing chamber, which is already at temperature and with the correct atmospheric conditions. After brazing, the load is cooled in the purge chamber. Proper atmosphere is required in the heating chamber before the load enters. Atmosphere having high oxygen concentrations, will oxidize the load and brazing will not occur. This is why a purge chamber or a vacuum purge is required in a batch application. Types Batch furnaces are of different types but the commonly used batch furnaces are box furnace and vacuum furnace. Box Furnace Of all the types Box furnace are commonly used batch furnace consisting of box-type design. They incorporates entry and exit doors, a heating chamber, and a water-jacketed cooling chamber. Vacuum Batch Furnace In Vacuum batch furnaces loading may be either in batch or it may be semi-continuous. Due to the inefficiencies relating to cooling the large mass of the vacuum retort, Vacuum furnaces are usually limited to smaller charges. To enhance the pace of the cooling, sometimes an inert or purge gas is introduced into the retort to speed cooling. The heat is protected through very well insulation system. Vacuum furnaces come in a variety of loading, material handling, and work zone configurations. Features
