Cement brick kiln used for firing zone, the average life expectancy of about 80 days, while the firing zone for the life of magnesia cement brick service life than doubled, and some will reach 400-500 days. However, the thermal expansion coefficient smaller than magnesia alumina brick height of about twice the thermal shock resistance is also very poor, but also easy to moisture deterioration, and only keep the use of attention, in order to give full play to the advantages. Intro about the use of magnesia technical measures: 1, pay attention to moisture: magnesia brick poor moisture resistance, moisture deterioration cracking losses, magnesite into the plant to be placed in a dry place, cover tarp, storage and strive to not expire. Do not burn magnesia during the rainy season the South preferably not more than 3 months, the North does not exceed six months, sintered magnesia can be slightly longer. Throwing handling to prevent and avoid collisions. 2, is preferable to the cylinder firing zone expansion and magnesia expansion substantially equal, to avoid magnesium bricks have a greater stress rupture. 3, due to the thermal expansion coefficient than magnesite brick, high alumina brick approximately twice as large as bricklaying leave when appropriate Zhuanfeng to prevent temperature rises expansion squeeze crack. Between the bricks slit width 2-3mm, slit width between windings 5-6mm. 4, drying and firing kiln, magnesite poor thermal shock resistance, thermal expansion coefficient and thermal conductivity are larger, in order to prevent temperature rise is too fast, brick burst, kilns have the appropriate system, that slower heating kilns, the Good take 120 ° c / time, the fastest does not exceed 200-250 ° c /, the other attached to the water inside the kiln lining is completely dried, then pulverized coal is rising gradually. 5, hanging good "kiln skin" protect "kiln skin", avoiding exposed red brick kilns. 6, good insulation work temporarily stop the kiln, magnesia poor thermal shock resistance, when the temporary stop the kiln repair equipment or grab complement other parts of the brick, you must turn off the two winds, so that the kiln temperature gradually decreased, especially when the "kiln skin "is not very good or when exposed brick insulation is more important, such as plans to stop the kiln, hang in advance make up" kiln skin ", protect magnesia brick.
