20 anni di produttori di refrattari in Cina
Founded in 2004, Kerui Refractory is an international high-tech enterprise
integrating R&D and innovation, manufacturing, solutions and service of high
-performance refractory products.
Kerui attached great importance on R&D. In the past decades, we’ve obtained
one invention patent certificate and more than 20 utility model patent
certificates. Kerui insists on technological innovation to provide customers with
better products.
Our products comply with ISO 9001, ASTM, EN, and GB standards. Specific materials meet REACH, RoHS, and industry-specific certifications (e.g., for steel ladle linings).
Our 12-step QC process includes:
– Raw material XRF analysis.
– Semi-finished product density/porosity tests.
– Final inspection: appearance inspection, chemical index testing, cold crushing strength, thermal shock resistance (ISO 3187).
– Batch-wise sample archiving (retained for 5 years).
Our certified technicians offer global commissioning support. Training videos and multilingual manuals included with all orders.
Our technical team offers free consultation services. Share your operational temperature, furnace type, chemical exposure, and mechanical stress requirements, and we’ll recommend optimized materials with supporting data sheets.
"Come direttore di un impianto siderurgico, utilizzo i mattoni di allumina di Kerui Refractory da 3 anni. La loro resistenza agli shock termici supera i concorrenti di 40%, riducendo in modo significativo i tempi di inattività. Anche a 1700°C, l'integrità strutturale rimane impeccabile. Davvero progettati per condizioni estreme!".
"Their engineers customized silica-mullite linings for our glass furnace within 72 hours. Detailed CAD drawings and thermal analysis reports exceeded expectations. Post-installation follow-ups ensured optimal performance. Technical mastery combined with responsiveness!"
"By switching to Kerui's high-performance castables, we reduced our annual refractory costs by 25%. Their products not only last longer but also require less frequent replacements, making them a cost-effective solution for our operations."
"Dall'RFQ alla consegna: 11 giorni. La riparazione d'emergenza del nostro forno per cemento nella stagione dei monsoni è stata gestita con precisione militare. La tracciabilità del carico in tempo reale e l'imballaggio a umidità controllata hanno dimostrato la loro eccellenza operativa. Un esempio da manuale di gestione delle crisi".
"Due anni dopo l'acquisto, il loro team ha diagnosticato a distanza i modelli di usura del rivestimento della siviera attraverso i nostri dati operativi. Gli aggiornamenti dei materiali consigliati hanno prolungato la durata della campagna di 90 cicli. Soluzioni proattive per la longevità, non solo vendita di prodotti".
"For our hydrogen-based direct reduced iron project, they co-developed a chrome-free magnesia-alumina spinel brick. 18% energy savings with zero flaking issues. Tailored to green steelmaking needs. Game-changing partnership!"
"From the first inquiry to final delivery, Kerui's customer service was impeccable. They accommodated our tight deadlines and provided regular updates, ensuring a smooth and stress-free procurement process."
"Their team provided an in-depth thermal conductivity analysis for our new kiln design, suggesting material optimizations that improved energy efficiency by 15%. Their technical insights were invaluable and delivered ahead of schedule."
"They developed a unique ceramic fiber module for our annealing furnace, reducing heat loss by 20%. Their innovative approach and willingness to experiment with new materials have set them apart from other suppliers."
"They didn't just supply materials; they also provided comprehensive training for our staff on proper installation techniques. This hands-on support has significantly improved our operational efficiency and product lifespan."
