The working technology of low temperature box type heat treatment furnace

Low temperature box type heat treatment furnace used for tempering and non-ferrous metal heat treatment. The heating mode can be divided into direct heating and separate heating. Direct heating thermal efficiency is high, but the workpiece tend to be direct thermal radiation caused by high temperature electric heating element local overheating, the solution is to put insulation plate between the workpiece and the electric heating element (such as charging box, etc.). Separation of heating is to use hot fan will be in the hot gas into the furnace. Separate low temperature electric box furnace used in the practical application is less, most used in the workshop or well type box-type furnace heat treatment at low temperature.
