Our high-alumina bricks (typically containing 50% to 85%+ Al2O3 content) can withstand maximum service temperatures ranging from 1500°C up to 1800°C, making them ideal for high-temperature furnace linings, ladle linings, and rotary cement kilns.

Yes, we specialize in custom engineering pre-cast pre-fired shapes (PCPF) tailored to your furnace designs and drawings. Our team fabricates block elements, burner blocks, pocket blocks, and custom shapes using high-purity castables, pre-fired at controlled heating cycles to guarantee thermal performance.

Standard refractory castables (conventional, low-cement, and insulating castables) have a lead time of 7 to 10 business days. Custom formulations or large bulk orders typically take 15 to 20 days. Contact our sales desk for emergency or fast-track shipments.

Yes! Alfa Refractories offers comprehensive engineering consultation and field supervision. Our experienced engineers provide dry ramming mass installation supervision, dry-out scheduling guidelines, and thermal calculation models to optimize furnace efficiency and refractories lifespan.

Absolutely. All our products are manufactured under strict ISO 9001:2015 quality control systems. We perform raw material testing, crushing strength verification, permanent linear change (PLC) testing, and bulk density analysis in our state-of-the-art laboratory before dispatch.
