Heat Treatment
Usage of the Carbon/Carbon composite instead of metal for loading racks allows to:
Increase energy efficiency, due to the very low thermal mass of Carbon/Carbon composite, your energy is being spent heating (and cooling) components rather than supports and fixtures.
Rapid heat up and cool down, also as a result of the low thermal mass
Material lightweight, allows for easier handling
No thermal deformation or creep, giving extended lifetime
Eliminates sticking of metal parts to rack surface
Increase of the productivity
Applications Carbon/Carbon loading trays and baskets are used for thermal treatment processes such as
vacuum brazing,
annealing,
low pressure carburizing,
gas quenching of automotive parts,
case hardening of steel parts with subsequent oil quenching etc.
The advantages of Carbon/Carbon composite to cast metallic trays: Energy saving
Carbon/Carbon trays use 5-10 time less energy than steel.
Improved energy efficiency of heat treatment processes with the possibility to reduce heating/cooling cycle.
C/C composites do not lose mechanical properties with temperature. Lightweight constructions are possible.
Lightweight construction
Density of Carbon/Carbon is 5 times less than steel: easy handling thanks to the weight reduction.
Easy automation. Handling by robots
Carbon/Carbon trays have no distortion or thermal creep.
CTE of C/C is 10 times less than steel.
Improved quality of treated parts
C/C composites have a self-lubricating surface. No sticking/brazing of metal parts to rack surface, therefore no deformation of the metal parts
Cost saving
No embrittlement, robust, increased lifetime
Increased loading capacity by optimized design
Thermal shock resistance increases with temperature
