Development Concepts for Porous Periclase MgO

Abstract

The repair of the lining in the sinter zone of the rotary kilns is needy on the constant, single sided exploit on the refractory of high temperatures (1650-1700°C) and the active loads developing during rotation of the kiln. The interrupted factors include changes in temperature and gas atmosphere, linked with the displacement of the material being fired across the surface of the lining. A new age group of porous plugs reduces the require for cleaning via oxygen lancing, improves safety and increases in commission life. Refractory mixes based on low cement or ultra low cement, high technology castables put in to the good performance. The experimental linings made from Periclase Spinel products undergo double testing in the mostbadly wearable (least heated) part of the sinter zone of one of the 90-m rotary kilns effective on the burning of caustic dust. © 2017 Elsevier Ltd.
