The challengeOf the 2,000 cement furnaces around the world, 100 percent of them have a critical 5 to 10-meter area that suffers extreme conditions due to high temperatures, chemicals, and liquid infiltration. These conditions force manufacturers to stop production and renew the refractory lining even when the majority of the lining (the other 60 to 70 meters) is in working condition.
The pause in production not only requires time and materials but also requires massive amounts of energy to restart the kiln after being shut down. This is extremely costly at a time when energy reduction methods are being used to offset the costs of rising energy prices around the world.
The goalOur customer turned to our experts to help them develop a disruptive solution for the cement industry. The goals were to:
- Avoid interruptions in production;
- Lengthen the life of the refractory lining in the cement kiln; and
- Formulate a new brick that could withstand 3 times the current life cycle.
The approachAfter promising lab trials, we developed a unique mix of different alumina grades that would work together to create a more durable solution with higher corrosion resistance, so that it could withstand the temperatures, chemicals, and water vapours generated in the kiln.
To ensure a smooth launch of the new solution, we offered a 500-ton consignment stock to support our customers’ peak production during the early days of the project. This helped to offset challenges regarding supply chain disruptions, material shortages, and price volatility.
The outcomeThe new solution has not only been reached but it has surpassed the initial durability goals for the lining. So far, our customer has seen results that extend the life of the refractory lining by 6 times, nearly double the initial hope of the project. As a result, there are fewer maintenance stops and cost savings in both energy and production.
Already, our customer has experienced higher productivity ratios in their plants and has since announced a global campaign to install this solution in their plants globally. Starting with a 500-ton contingency, we have now grown our relationship with our customer to provide 2,000 tons each year, with further growth on the horizon.
Today, cement production accounts for nearly 7 percent of global CO₂ emissions and 90 percent of the energy used in cement manufacturing lies solely in kilns. Innovations like these have the potential to drive massive change in the industry and have huge sustainable benefits to our world.
