The Insulation Layer Of Vacuum Heat Treatment Furnace Is Mainly Used For Cylindrical Reasons

---

Vacuum Heat Treatment Furnace Insulation Layer of the Main Uses

First, the heat insulation layer of vacuum heat treatment furnace is one of the important parts of the heating chamber. Under normal circumstances, the heat insulation layer is made of cylindrical as far as possible, because, from the point of view of heat transfer, cylindrical structure, its heat transfer effect is better, and the heat loss is very small.

Second, the interior dimensions of vacuum heat treatment furnace heat insulation layer is the size of the chamber of a stove or furnace, this size is according to the shape and size of processed workpiece and furnace production points to decide, and you also need to consider the effect of vacuum heat treatment furnace heating, the uniformity of furnace temperature and convenient maintenance and discharging operation, etc.

Third, the distance between the inner surface of the heat insulation layer of the vacuum heat treatment furnace and the heater is about 50 to 100 mm, and the distance between the heater and the workpiece, fixture or basket should be about 50 to 150 mm.

Fourth, the heat insulation layer of vacuum heat treatment furnace near the furnace door and the back wall at both ends of the temperature is relatively low, so the distance between the workpiece and the ends needs to leave 150 to 250 mm.The selection of the material and thickness of the heat insulation layer of vacuum heat treatment furnace is generally determined by the vacuum degree and working temperature of the furnace.

Fifth, the heat insulation layer of the vacuum heat treatment furnace, it is the place where the workpiece is heated. It is mainly used for heat insulation, heat preservation, and heat loss construction. In some cases, the heat insulation layer of the vacuum heat treatment furnace is also the structural basis of the fixed heating element.Vacuum heat treatment furnace heat insulation layer according to the choice of materials and different structural forms, can be roughly divided into five types: refractory furnace lining, sandwich type heat insulation layer, all metal anti-radiation screen, mixed blanket insulation layer and graphite blanket insulation layer.

The Reason for the Cylindrical Insulation Layer

First, the heat insulation layer of the vacuum heat treatment furnace is where the workpiece is heated. Its main role is heat insulation, heat preservation and heat loss reduction.

Second, in general, the heat insulation layer of vacuum furnace is made of cylindrical as far as possible, from the point of view of heat transfer, cylindrical structure, its heat transfer effect is better, heat loss is very small.The internal size of the heat insulation layer is the size of the furnace, which is mainly determined by the shape and size of the workpiece being processed and the production of the furnace.

Thirdly, it is also necessary to consider the heating effect of vacuum heat treatment furnace, the uniformity of furnace temperature and the convenience of maintenance and loading and discharging operation, etc.In general, the distance between the inner surface of the vacuum heat treatment furnace insulation layer and the heater is about 50 to 100 mm, and the distance between the heater and the workpiece, fixture or basket should be about 50 to 150 mm.

Fourth, the vacuum heat treatment furnace heat insulation layer according to the choice of materials and different structural forms, can be roughly divided into five kinds: refractory furnace lining, sandwich type heat insulation layer, all metal anti radiation screen, mixed blanket insulation layer and graphite felt insulation layer.
