Frequently Asked Questions

What is the service life of Magnesia Carbon Bricks?

Typical service life ranges from 1,500 to 3,000 heats depending on furnace type, operating conditions, and brick grade. Proper installation and maintenance are critical.

Can Ceramic Fiber Blanket be used in direct flame applications?

Standard ceramic fiber blankets are not recommended for direct flame impingement. For such applications, we offer specialized coatings or rigid fiber boards with higher erosion resistance.

Do you offer custom refractory shapes?

Yes, we provide refractory precast shapes and custom-designed bricks based on technical drawings and specifications. Our team supports OEM and project-specific requirements.

What certifications do your products have?

Our products comply with ISO 9001 standards. We provide material test reports (MTRs) and can meet ASTM, GB, and other international specifications upon request.
