Not all rollers work in the same way inside a ceramic kiln. Thermal, chemical and mechanical conditions vary from zone to zone, and this makes it necessary to select the right roller according to its technical performance.
ICRA has different formulations within the Pyroxal® range, but there are two models that should be carefully compared: Pyroxal® 50 vs Pyroxal® HT.
What are the key differences?
Working temperature
– Pyroxal® 50: High
– Pyroxal® HT: Extremely high – critical furnace zones
Stiffness and deformation
– HT has a higher elastic modulus, which makes it more resistant to deformation in areas of high load or non-uniform thermal expansion.
Heat distribution
– HT has higher thermal conductivity, useful in areas of intense and changing heat.
– 50 is sufficient for more stable sections of the thermal cycle.
Durability in aggressive environments
– 50 excels in chemical resistance and residue adhesion, extending its useful life where vapors are more corrosive.
Which one to choose?
Pyroxal® HT is suitable for large furnaces, central firing areas, maximum thermal and mechanical requirements.
Pyroxal® 50, on the other hand, is suitable for transition areas or sections with lower thermal and chemical loads. It is a good option to maintain performance without oversizing.
Choosing the right type of roller is key to prevent deformation due to thermal fatigue, minimize downtime due to breakage and optimize process efficiency.
A good technical choice starts inside the furnace.
