Monolithic refractory products are dry-mixed materials. They must be finalized through on-site water mixing, pouring, vibration, curing and an extremely dry-out process. The advantage is that it is not limited by complex furnace shapes and can fit the corners very well. Of course, quality and stability of refractories and monolithics are undoubtedly paramount to the kiln’s service life. REBO completes the production and quality inspection in own factory. This is a key reason why customers both domestically and internationally choose us.
What are Monolithic Refractory Products?
As the name suggests, unshaped refractories refer to refractories that do not have a specific shape, and are supplied in bulk. They can be processed into any shape.
After receiving them, you only need to mix them with water or a binder before pouring, spraying, tamping, or coating to form the desired shape. They can be used on-site without pre-sintering. Their core advantages over shaped refractories are: seamless integrity, flexible installation and rapid repair.
REBO Project Applications
RUSAL Project: Complete Unshaped Refractory Material Solution
After order testing, based on the outstanding performance of the first batch of products, the RUSAL client subsequently decided to entrust REBO with the exclusive R&D and production of all subsequent refractory materials for the entire project. Since 2023, our team of technical experts has personally visited the RUSAL production site annually for comprehensive operational inspections, successfully establishing a long-term global strategic partnership between the two parties. Choosing REBO means you and RUSAL are using the same supplier!
Colombian Cement Kiln Project
A large cement plant in Colombia had previously suffered from shutdowns due to unstable kiln refractory linings and premature wear caused by thermal stress. Through in-depth technical collaboration, the REBO engineering team accurately diagnosed that the traditional materials in the high-temperature fluctuation zone had severely insufficient erosion resistance. Therefore, we customized a high-strength, anti-sparging refractory castable for the client, working in conjunction with special refractory bricks. This solution perfectly mitigated the destructive forces caused by drastic temperature fluctuations. Currently, the cement rotary kiln is operating stably, with a significant improvement in overall thermal efficiency, greatly reducing maintenance costs for the client.
Indonesia Incinerator Project
A waste incineration project in Indonesia has placed bulk orders with REBO for several consecutive years. Addressing the complex furnace structure and extremely harsh environment of toxic gas scouring, REBO has provided a seamless integrated “brick-mortar-insulation” lining solution. This minimizes the risk of highly corrosive flue gas erosion of the furnace’s steel shell, ensuring the long-term safe operation of the incinerator and marking another benchmark achievement for REBO in the field of environmental thermal engineering in Southeast Asia.
A Comprehensive Analysis of REBO Unshaped Refractory Materials
Production Equipment
In 2025, REBO fully upgraded its intelligent industrial production line, achieving fully automated production of unshaped products such as castables, refractory cement, and refractory mortar. This effectively ensures the consistency of physical and chemical properties across each batch. REBO’s modern manufacturing base is located in Chaohua Industrial Zone, Xinmi City, Henan Province, adjacent to a world-leading raw material supply chain and cutting-edge refractory material production processes.
Production Capacity
As a reliable backbone of the global high-temperature industry, REBO and the KERUI Group have a total annual output of 280,000 tons, with an annual production capacity of over 100,000 tons of unshaped refractories. In short, REBO has the capability to undertake large-volume, long-term strategic procurement contracts from multinational corporations. Benefiting from the group’s mature international logistics and compliance system, our export scale has steadily expanded year by year, providing continuous supply to customers in the global steel, cement, glass, and petrochemical industries.
Quality Assurance
Quality is the cornerstone of industry. REBO unshaped refractories have passed and strictly adhere to the ISO 9001 / ISO 14001 / ISO 45001 systems, and have simultaneously obtained authoritative third-party certifications such as CE and SGS. Furthermore, the factory’s quality inspection center ensures that every kilogram of unshaped refractories meets the required standards. Every batch of products delivered to major clients is accompanied by a quality inspection report.
Technical Support Depth
REBO boasts a technical team of over 20 professional engineers covering formulation development, construction processes, and application guidance, providing clients with full-cycle technical support for projects. We offer construction guidance, furnace drying solutions, and on-site follow-up services to ensure optimal product performance under actual working conditions.
