In the ironmaking process, the blast furnace or direct-reduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln. Many producers use a traveling grate and rotary kiln to heat the pellets to temperatures as high as 800°C to 900°C in the preheat zone and as high as 1200°C to 1300°C in the burning zone of the kiln. These are typically fed to a blast furnace or DRI plant as part of the process to make iron and steel.

The rotary kiln is typically lined with rotary kiln brick like KRUZITE®-70 or ALADIN® 80 and maintained using monolithic refractories. There are coolers associated with the kiln for cooling the pellets before transport to a loadout facility. Monolithic refractories like VERSAFLOW® 70 PLUS and GREENGUN®-85 P PLUS are used to maintain these areas.

KRUZITE®-70 is a 70 percent alumina brick with excellent spalling resistance and hot load strength. ALADIN® 80 has good strengths and thermal-shock resistance and the lowest porosity of any brick in this class. These features provide for excellent service in the burning zones of the taconite kilns. Monolithics such as VERSAFLOW® 70 PLUS are used where abrasion resistance and high hot strengths are needed in the coolers and other areas for maintenance. GREENGUN®-85 P PLUS is used for its high hot strengths and abrasion resistance and is especially good in areas where you need high resistance to thermal cycling.
