A METHOD OF PRODUCING AN ABRASION RESISTANT CERAMIC LINER IN THERMAL POWER PLANTS

摘要

The invention relates a method of producing abrasion resistant ceramic liner for transportation of coals in thermal power stations produced at low sintering temperature with high sintering range consisting of wt. % of alumina 80%, an aluminosilicate and oxide additive mixture not exceeding 20%, and manganese oxide additive of 1 % with organic binding adhesive of 10-15% concentration, the method comprising the steps of a)dry mixing in a high speed mixer said ingredients; b) pressing the moist powder in the form of tiles of different sizes and shaping by a hydraulic press; c) natural drying of the formed tiles; d) sintering the tiles in a batch kiln furnace at 1500 - 1550°C temperature to obtain a high abrasion resistant tile of BD : 3.38-3.42 g/cc and water absorption property of 0.02-0.05 %, RAI of 22-28 with homogenous dense microstructure.
