Blast Furnace Charging Systems
Raw material input is one of the most important control variables for optimized blast furnace operation. Both the accuracy and reproducibility of the charging process and the reliability and ease of maintenance of the charging equipment are critical.
Saint-Gobain Performance Ceramics & Refractories helps customers to achieve these goals by providing custom, wear-resistant ceramic solutions for blast furnace areas outside of the bosh, stack and hearth. Saint-Gobain Performance Ceramics & Refractories’ wear-resistant technologies can be used in a range of applications, including:
- Receiving hopper
- Revolving hopper
- Lock and holding hoppers
- Diverters
- Charge end sockets
- Discharge funnels
- Conical sockets
- Equalizing relief piping and uptakes

FAQ
Sinter is a very dense, abrasive material that requires special attention when designing ceramic solutions. Saint-Gobain Performance Ceramics & Refractories’ engineers have successfully designed and installed numerous ceramic lining systems for blast furnaces utilizing sinter.
Ceramics have been found to perform 3-5 times better than chrome carbide overlay in terms of wear resistance, depending on the application.
Installation cost varies depending on specific customer requirements, equipment, and operating conditions, but customers have reported that overall installation costs are similar to the cost of installing AR steel wear panels.
The total cost of ownership of ceramics is considerably less over the life of the installation versus traditional lining materials.
