How do I choose the right alumina content?

Decide from the furnace working temperature and chemical load. Fireclay is enough up to ~1,350°C; hotter or abrasive applications need 60–80% high-alumina. Send your temperature profile and furnace charge type for a recommendation.

What is the difference between dense and insulating brick?

Dense brick (firebrick) withstands direct flame contact and mechanical load; insulating brick (IFB) is low-density and used as a back-up layer to retain heat and save energy. The two are often used together.

Do you supply special shapes (arch/wedge)?

Yes. Besides standard straights, we supply arch, wedge and checker shapes, including custom shapes to drawing with import lead time.

Do you supply refractory mortar for installation?

Available — refractory mortar and matching castables are on the castable page. We help match the mortar to your brick grade.

Refractory Bricks

A failed lining is not just a broken brick — it means a stopped furnace, disrupted production schedules and unplanned shutdown costs. Choosing the right refractory brick, matched to working temperature and chemical load inside the furnace, is an investment that pays for itself through longer lining life.

We supply dense and insulating refractory brick with alumina content from fireclay to high-alumina for steel, cement, glass, ceramic and petrochemical plants.

Brick types we supply

Fireclay (Al₂O₃ 30–45%) — versatile brick for medium-temperature linings up to ~1,350°C: boilers, small furnaces and flues.
High-alumina (Al₂O₃ 60–80%) — higher temperature and mechanical-load resistance up to ~1,650°C for melting furnaces and kilns.
Insulating brick (IFB) — low density for back-up layers, retaining heat and saving energy.
Magnesia & chrome-mag — for basic environments such as cement rotary kilns and certain furnaces.
Special bricks — silica, mullite and special shapes (arch, wedge, checker) to order.

Specifications & sizes

Standard straight size 230×114×65 mm and its derivatives, plus arch and wedge shapes. We include refractoriness, cold crushing strength (CCS), porosity and PCE data so selection fits the application. Special shapes can be ordered to drawing.

Applications by industry

Steel: ladles, tundishes and reheating furnaces. Cement: rotary kilns and preheaters. Glass: tank furnaces and regenerators. Petrochemical: heaters and reformers. For monolithic linings and joints, see refractory castables & insulation.

Sourcing & lead time

Common types (fireclay, standard high-alumina) are stocked for 3–10 working-day delivery; special shapes and high grades are imported in 4–8 weeks. Large relining volumes are scheduled to your shutdown timeline.

Quality assurance

Factory data sheets with chemical composition and physical properties are included; for critical projects we provide batch test results.
