![]() Check the kiln operation when bad skin condition
"Kiln skin" thickness, a direct impact on the life of the kiln lining, long-term safe operation of the kiln and kiln completion of the technical and economic indicators, so
you must always pay attention to "kiln skin" changes. Happen "kiln skin" thinning or peacetime, should take timely and effective measures, and strive to extend the safe operation of the kiln cycle. First, check the "kiln skin" case 1, from looking at the fire hole observed no discharge zone "kiln skin" is flat. If the "kiln skin" formation, was slightly white, but the same color throughout, indicating that the entire "kiln skin" the same thickness as normal. If you find the color and shade of the points, or the black hole, then "Kiln skin" has collapsed down of the black holes are "kiln skin" just collapse, the bottom temperature is low, colors were dark. 2, by looking at the "shadow" shape to distinguish "kiln skin" is formed, when the "kiln skin" formation, "shadow" in the lower part of the flame into a linear form, such as "kiln skin" is not flat, then the "shadow" into a curve-shaped, "kiln skin" concave and convex portions larger "shadow" the greater part of the curve. 3, check the temperature of the cylinder water-cooled, water-cooled cylinder when the temperature generally increased, indicating "kiln skin" widespread thinning, if water cooled cylinder high local temperatures, indicating high temperature "kiln skin" thin, this water cooling local area or cylinder water evaporates too quickly dried up, that is, red kiln signs, then "Kiln skin" caving or thin bricks have been burned, not even brick, urgent measures should be taken immediately. As the "kiln skin" caving, cylinder temperature, when the cylinder temperature rose to 400-500 ° c, the temperature at night can present crimson, when the temperature reaches 400-600 ° c, the dark red, that is called "red kiln." Second, the "kiln skin" bad or out "kiln skin" when operating one, found that "kiln skin" local thinning, you should move the location of coal burner, avoiding the high point falls "kiln skin" weak, while in the "kiln skin" thin parts increased leaching of water, in order to fill hanging "kiln skin" to create favorable conditions. 2, when the "kiln skin" widespread thinning should reduce feeding slow down kiln speed, strict control of end grain temperature, a full complement of hanging "kiln skin." 3 found kiln thin skin pitting or partial loss supplement linked to timely prevent red kiln. If red kiln, should take immediate measures to stop the kiln, organizational overhaul. Such as magnesia refractories, red kiln must not stop the kiln, processing methods: appropriate to reduce the kiln temperature, reducing kiln exhaust or less expected, moving coal injection nozzle position, move the cylinder cold location, make new kiln leather hang .
