Carbolite HTRH-GR graphite tube furnace

1、 Product Introduction:

The maximum temperature of the Kabolette Gallo graphite tube furnace is 2600 ° C. Optional adjustable angle base, capable of adjusting different angles for horizontal or vertical use.

This series of cold wall furnaces uses graphite heating elements and insulation material is graphite felt. In the relatively high temperature range of 400 to 600 ° C, graphite reacts with oxygen in the air, so it needs to work in an inert atmosphere or vacuum. To ensure an oxygen free environment, the tube furnace needs to be placed in a water-cooled vacuum chamber and sealed with an O-ring, which can be pre evacuated and filled with an inert atmosphere before heating.

Graphite felt insulation material has very low thermal conductivity and is an excellent furnace insulation material. Insulation materials of different thicknesses and qualities will be carefully selected according to the maximum temperature of the furnace.

4、 Technical parameters:

5、 Attention:

1. When the temperature is below 2000 ° C, the heating rate is about 10 ° C/minute, and above that, it will be relatively slower

2. 380-415V three-phase electricity, neutral wire and ground wire

3. In addition to the existing diameter of the working pipe, there is also an outer diameter of 800mm

4. Inert atmosphere and cooling water must be configured

5. The maximum continuous use temperature should be 100 ° C lower than the maximum temperature

6. Above 2000 ° C, the loss of heating elements will increase exponentially with the temperature rise
