1. Resistance to heat and thermal shock
4. Mechanical stability in conditions
Cement kilns and mills produce constant vibration. Due to their dense structure and precise heat treatment, fireproof bolts and nuts are resistant to mechanical fatigue and long-term vibrations and prevent loosening of connections.
5. Application standards
In the sensitive parts of the cement industry, refractory screws are usually used according to international standards such as DIN 912, ASTM A193 Grade B8, B8M, or AISI 304/316, which guarantees technical compliance and safety in the long-term operation of the equipment.
