3 Case Studies of REBO Refractory Cement

Emergency Repair of EAF Linings in Europe

The taphole of an electric arc furnace at a European steel plant had long suffered from erosion caused by high-temperature molten steel and slag. Traditional refractory materials cured slowly, resulting in prolonged furnace downtime and significant production losses. REBO uses rapid-hardening, high-strength gunning mixes and castables—formulated with high-purity aluminate refractory high temp refractory cement applied via automated robotic arms to perform rapid spray repairs while the high temperature furnace cement remained red-hot from residual heat.

Monolithic Lining for CFB Boilers in America

A CFB boiler at a large U.S. power plant operates at a temperature of approximately 1,050°C. Its lining is subjected to continuous erosion by high-velocity particles and limestone, limiting the service life of conventional materials to around six months. Last year, REBO introduced a low-cement refractory castable solution; by strictly controlling the mix proportions, the company significantly reduced apparent porosity to create a dense lining, thereby extending the service life from six months to over 24 months.

Dual-Layer Lining for Petrochemical FCCU in Middle East

A large oil refinery in Saudi Arabia features refining pipelines and reactors densely packed with anchors, making the installation of refractory brickwork particularly challenging. Following an assessment, REBO adopted a dual-layer monolithic casting solution, combining ainsulation layer with lightweight refractory cement working layer. This approach ensured the delivery of the entire system as an integrated unit.

3 Main Applications of REBO Refractory Cement

Formulating Other Monolithic Refractory

Refractory cement serves as an excellent binder. Acting as a base powder, it is used to formulate refractory castables, mortars, and other monolithic refractory materials. Once prepared, the mixture can be cast or pumped directly onto critical areas—such as furnace walls, roofs, and piping in industrial kilns—to form a seamless, monolithic refractory lining.
>It is used in the formulation of monolithic refractories and specialty moldable refractory cement (such as gypsum-bauxite expansive cement and self-stressing high temp furnace cement), as well as in projects requiring rapid construction, emergency repairs, or resistance to sulfate attack.

Resisting Chemical Attack in specific industrial environments

Refractory cement offers not only high-temperature resistance but also excellent chemical inertness. Industrial units such as waste incinerators, biomass boilers, and petrochemical fluid catalytic cracking units (FCCUs) often operate in environments filled with highly corrosive gases and acidic or alkaline slags. High-purity refractory cement effectively resists chemical attack from these harmful substances, preventing premature embrittlement or structural spalling of the lining.

Emergency Repair and rapid maintenance

In heavy industries (such as steel, cement, and petrochemicals), unplanned localized kiln shutdowns result in significant economic losses. Refractory cement price is characterized by rapid hardening and high early strength (often achieving substantial mechanical strength within 24 hours of casting). When localized lining spalling, cracking, or erosion occurs, technicians use kiln refractory cement to formulate specialized ramming mixes, repair compounds, or gunning mixes. These are applied to perform rapid, emergency “patch” repairs on damaged areas, thereby minimizing downtime for maintenance.

Types of REBO Refractory Cement

From standard SK-grade high alumina lining bricks to custom-engineered solutions, REBO supplies the full range of high alumina firebricks for steel, cement, glass, and non-ferrous metal industries. Specifically, Al₂O₃ content ranges from 40% to 99%, including popular options such as the 70 alumina fire brick. With that in mind, find your match below.
Al₂O₃ content available: 60%, 65%, 70%, 75%, 80%.

CA50 Refractory Cement

A600: Features rapid setting and hardening; primarily used for formulating conventional high temperature refractory cement castables.
A700: Offers stable setting and hardening characteristics and excellent workability; used for formulating medium- and low-cement castables.
A800: Formulated using bauxite and high-purity limestone with low levels of harmful impurities; used for formulating low-cement castables.

CA70/75 Refractory Cement

CA70: Includes CA70S and CA70W; “S” stands for Summer (suitable for high-temperature environments), and “W” stands for Winter (suitable for low-temperature environments).

CA80 Refractory Cement

CA80: A high-purity product with an alumina content exceeding 78%; features high early strength and high residual strength at intermediate temperatures. Suitable for formulating various conventional and low-cement castables; the resulting castables exhibit high load-softening temperatures, excellent slag resistance, and superior resistance to mechanical shock, with a service temperature of up to 1800°C.
CA80S: Offers superior flowability, extended working time, and lower water demand. It enables the formulation of castables with excellent workability and mechanical strength without the need for setting modifiers; suitable for high-temperature environments.
