Top liner plate expert Rio-Carb has successfully delivered R4 million-worth of Chromium Carbide (CrC) solutions for the largest cyclones in Africa, which form part the manufacturing plant belonging to an industry-leading cement producer.

The cyclones are used as components of kiln pre-heaters, and measure 12 m in height. Due to the fact that these cyclones are the largest on the continent, the project was under negotiation for two months and took another three months to complete.

Rio-Carb director Martin Maine highlights that all the design, detailing, plasma cutting and rolling was first done on a trial basis at Rio-Carb’s 3 000 m2 state-of-the-art facility to ensure that the parts fitted perfectly once they were delivered to site.

“All of this was done at our factory, as the plasma cutting could not have been done on site. Due to the sheer size of the structure, the transporter was designed into two pieces. It also had to be transported and erected in two pieces, which is why the trail fit up was necessary,” he says.

Rio-Carb’s modern facility features a computer-aided design (CAD) plasma control centre, which is able to streamline the productivity of the company’s plasma cutting machines by ensuring extremely accurate sizing and nesting of components.

Maine points out that all of Rio-Carb’s processes – from design to CrC cladding, high definition plasma cutting, rolling, welding, painting, studding and thermal zinc spraying – can be carried out under one roof, ensuring quality control.

“Rio-Carb is also the only liner plate manufacturer in South Africa whose welding standards meet the requirements laid out by American Welding Society (AWS), which guarantees the highest standards of quality and reliability. We believe that the standards we work to and our timing played a large part in Rio-Carb being chosen for this project,” he concludes.
