low-temperature box-type heat treatment furnace
The low-temperature box-type heat treatment furnace is used as heat treatment for tempering and non-ferrous metals. The heating method is divided into direct heating and separation 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.)
The separation heating is carried by a hot fan to the furnace. The low temperature box type electric furnace is used less in practical application, and the most used in workshop is the well – type low-temperature box type heat treatment furnace.
