Blast Furnace Iron Runner Precast Overhaul
Frequent iron runner relining caused long downtime. Precast trough segments and quick-change blocks cut the overhaul from 5 days to 2 days and are expected to extend runner life by over 30%.
View All Cases →
Cement Rotary Kiln Nose Precast Protection
Frequent thermal shocks caused nose castable spalling. High-alumina/corundum precast blocks replaced cast-in-place lining, lifting life by about 40% and extending the maintenance cycle from 6 to 9 months.

CFB Boiler Wearing Zone Abrasion-Resistant Reline
Dense-phase zones suffered severe particle abrasion. A steel-fibre reinforced SiC wear-resistant lining extended the continuous run from 8 to over 12 months.

FAQ
FAQs
Answers on selection, installation and purchasing
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.
