There is no danger that the temperature of kiln surface about 300 degrees centigrade. Fire workers must strictly observe if the temperature of kiln surface is higher than 400 degrees centigrade. If the temperature of kiln surface is reaching to 400 -- 600 degrees centigrade and it can observe the color change of the kiln body at night. It is red kiln in rotary kiln, if there is dark red of the rotary kiln surface. When the temperature of the kiln shell exceeds 650 degrees centigrade, the kiln body becomes bright red, and the kiln shell may deform.
