FAQs

What is the difference between castables and refractory bricks?

Castables are monolithic refractories formed by casting or gunning on site, ideal for complex shapes and integral linings with fast installation. Refractory bricks are pre-fired shaped products for regular structures requiring high erosion resistance. We offer integrated solutions for both, please share your service conditions (temperature, media, zone) for selection advice.

What service temperature ranges do castables cover?

Castables typically cover 900℃ to 1800℃: lightweight insulating 900-1400℃, high-alumina 1400-1600℃, corundum grades up to 1700-1800℃. Selection depends on the zone, atmosphere and expected service life.

What should be noted during castable installation?

Key points: strictly control water addition, use forced mixers with proper mixing time, secure formwork, vibrate to full density without over-vibration, keep the cast moist during curing, and follow the drying curve during first heat-up to avoid explosion. We provide free installation guidance and on-site service.

What are the advantages of precast blocks over cast-in-place?

Precast blocks are formed, cured and pre-fired in factory: consistent quality, high dimensional accuracy, much faster on-site installation that shortens outage time, and no site curing or baking needed. Ideal for tight outage schedules and complex furnace geometries.
