Movements

Movement of sample

For several reasons heat treatment sometimes needs to be combined with some sort of movement. Carbolite Gero offers a wide range of sample movements before, during and after heat treatment in standard and custom made ovens and furnaces.

A continuous movement of fluids inside an oven can be achieved by upgrading a standard oven to be fitted with electric drives and a shaft.

During the Bridgman method of crystal growth, the growing crystal is moved out of the furnace hot zone furnace into the cold zone at a rate of less than 0.1 mm per hour. During this process a smooth movement is essential for the quality of the growing crystal.

Ageing testing and thermal cycling

Thermal cycling furnaces are used for continuous material testing, primarily for ageing.

The automated cycling mechanism moves the sample material into the hot zone and once at the desired temperature it is held in position for a pre-defined period of time. After this dwell period the sample material is moved to an air quench zone where the temperature is reduced to a pre-defined temperature. This cycle is repeated as many times as required.

Most thermal cycling furnaces are equipped with cascade temperature control, probe thermocouples located near the sample and a data logger for quality control.
