MAGNESIA SPINEL BRICK FOR CEMENT ROTARY KILN

摘要

PURPOSE: To improve the coating characteristics to a level unachievable by any conventional technique and to improve the strength and lower the thermal conductivity. ;CONSTITUTION: Natural chromium ore having particle diameter of 1-3mm is included in the subject brick in an amount of 1-10wt.%. The obtained brick has excellent coating characteristics, high strength (compressive strength of about 550-600kg/cm²) and low thermal conductivity (4.0-4.2Kcal/mh°C) and exhibits remarkably improved effect compared with the brick free from natural chromium ore.;COPYRIGHT: (C)1994,JPO&Japio
