The Gero Carbolite HTRV 100-250/18 is used to observe the dissolution properties of slag formers and steel scrap in liquid slag and metallic liquids, respectively. Further, the determination of liquid slag properties e.g. diffusion coefficients is possible. The maximum temperatures are 1720 °C. The heating is carried out through molybdenum disilicide (MoSi₂) heating elements with a heating rate up to 300 K/h. The investigated sample is axial transported through a pneumatic transportation unit which allows to insert the cold sample into the heated melt. The transport unit is rotatable in design, allowing rotational speeds up to 100 rpm for dynamic processes. The closed furnace chamber allows experimental investigations under defined, oxygen-free atmospheres with nitrogen or argon. An additional thermocouple of type B in the centre of the furnace is available for the definition of the real sample temperature. An inspection window allows a visual evaluation of the moved sample after the immersion.

Further possibilities for usage: annealing, carbonisation, crystal growth, debinding, degassing, drying, glowing, hardening, metal injection moulding (MIM), pyrolysis, rapid prototyping, sintering, sublimation, synthesis, tempering

Principles and advantages of HTRV with adjustable gas atmosphere:

• sample holder which allows a movement into z-axis and rotation of the sample
• rotational speed of the sample up to 100 rpm
• adjustment of gas atmosphere
• maximum crucible diameter 60 mm with a height of 80 mm
• submerging of cold samples into hot liquids
• heating rates up to 300K/h
• programmable 3216P1 controller for defined temperature programs
