AC 30 S (230x115x75 mm)
Caldezone supplies AC 30 S high alumina refractory bricks with dimensions 230 x 115 x 75mm, manufactured by Calderys India Refractories from their Nagpur, Maharashtra facility. These bricks contain greater than 50 percent Al2O3, placing them in the high alumina fireclay category with superior refractoriness and thermal shock resistance compared to standard fireclay products. The standard arch brick dimensions suit rotary kiln, furnace, and boiler lining applications where precise brick courding and thermal stability are critical.
High alumina refractories derive properties from mullite and corundum formation during firing, with alumina content dictating maximum service temperature and slag resistance. AC 30 S bricks are engineered for cement kiln burning zones, petrochemical reformers, direct reduced iron rotary kilns, reheat furnaces, and iron making vessels where alkaline and thermal cycling resistance outweigh pure temperature capability. The 230 x 115 x 75mm size is a standard straight brick format allowing 114mm wall thickness with nominal mortar joint, compatible with universal anchoring systems and curved lining adaptations.
Buyers in cement production, steel making, petrochemical processing, and non-ferrous metallurgy procure these bricks for new lining installation and repair campaigns. When sourcing from Caldezone, confirm the exact Al2O3 percentage, bulk density, cold crushing strength, and refractoriness-under-load for your peak operating temperature. Discuss whether Calderys India provides installation supervision, refractory engineering calculations for lining design, or performance guarantees tied to campaign life in your specific process conditions.

Caldezone is listed as a supplier of Calderys India Refractories products, with the underlying manufacturer headquartered at 6th Floor, Fidvi Tower, Mount Road, Sadar, Nagpur, Maharashtra. Calderys India is part of the global Calderys group with established refractory production for cement, steel, and petrochemical industries. The Caldezone listing carries a Harbor trust tier, though platform response metrics show zero recorded activity, so direct communication reliability should be tested with initial inquiries.
The supplier profile does not state Caldezone's specific role, whether authorized distributor, trader, or broker for Calderys India products. No inventory holding capacity, technical staff qualifications, or project reference list is provided. Buyers should request Calderys India's authorized distributor certificate for Caldezone, confirm warranty and claim pathways, and verify whether technical support including refractory design and installation supervision flows through Caldezone or requires direct Calderys engagement.

Sourcing AC 30 S Refractory Bricks from Caldezone - India Import Guide
Before ordering AC 30 S from Caldezone, verify your Calderys India authorization status and request recent batch test certificates showing actual Al2O3 percentage, bulk density, and CCS values rather than catalog specifications. Inspect sample brick for uniform firing color, absence of cracks or laminations, and dimensional accuracy with your gauge. Confirm whether Caldezone or Calderys India provides refractory engineering support for lining design, and establish technical contact for installation queries or campaign performance issues.
Shipping from Nagpur typically routes via Jawaharlal Nehru Port (Mumbai) or Hazira Port for sea freight to global destinations. Confirm Incoterms with Caldezone, whether EXW Nagpur, FOB Mumbai, or CIF destination, and clarify responsibility for inland haulage, port handling, and export documentation. Payment structures for Indian refractory exports often involve letter of credit or advance payment with bank guarantee; negotiate terms reflecting your relationship depth and order scale, and document all agreements formally.
Quality verification on arrival should include random sampling for dimensional check, weight consistency as proxy for density, and visual inspection for transit damage or moisture exposure. Engage a third-party inspection agency to witness loading if container stuffing is at Nagpur, and require packing lists with batch numbers traceable to Calderys India production records. For critical applications, retain samples from each batch for post-campaign forensic analysis if premature lining failure occurs, and establish warranty claim procedures with Caldezone before shipment dispatch.
