The newest generation of SOL-GEL castables for fast heating up conditions
Heating-Up problematic of standard dense monolithics :
─ Dehydration of the hydrat phases. Starting at 350°C.
─ Danger of spalling and explosions caused by steam forming if the heating up process can not be regulated properly.
Solution: Use of dense castables with a SOL-GEL setting system. VIBROLIT CASTING
Benefits of the VIBROLIT / NANO-G castables :
─ No hydrat phases, but a cross-linked Gel – Structure
─ High permeability of Gel – Structure. No chemical bounded H2O inside the castable
─ Possibility to heat up faster. Reduced danger of explosions and spalling
─ Better chemical resistance, less build up
─ Improved high temperature properties ( e.g AT, hot mechanical & errosion properties )
─ Longer storage lifetime ( min. 12 month )
