Coke-calcining plants receive green petroleum coke from oil refineries. The green coke is blended and fed into rotary kilns operating up to 2800°F under a reducing condition. The material exits the rotary kiln as calcined coke with a correct crystalline structure and electrical conductivity properties. These coke properties allow this product to be sold to the primary aluminum industry for use in aluminum reduction cells.
KRUZITE®-70, a dense firebrick for the burning zone of rotary kiln linings, offers the benefit of kiln-shell temperatures below 450°F, with the ability to resist thermal shock caused by intermittent operations or kiln-variable feed rates. An added benefit is its availability in a large variety of shapes and sizes to match your changing requirements on a worldwide basis.
ULTRA-EXPRESS® 70, a dense, ultra-low-cement castable, will match the properties of KRUZITE®-70 firebrick with the additional benefit of faster installation speed by pumping to minimize downtime. This product also demonstrates enhanced stability in areas of the rotary kiln shell that are warped.
VERSAFLOW® 57A PLUS, a dense, low-cement castable, is our unique thermal-shock-resistant monolithic for rotary kiln linings such as air injection nozzles or kiln lifters. A special additive within VERSAFLOW® 57A PLUS allows this product to withstand extreme thermal shock conditions and maintain lining reliability during plant upset conditions.
