Rotary kiln, as a kind of large calcining
industrial kiln furnace, has many operating rules for operators. Obviously, the temperature in the calcining process will reach a pretty high level. You may ask how I can keep the temperature in a normal range. There is no doubt that before starting feeding, the temperature rising process should follow a certain rule. Under present technical condition at home, the temperature rising curve is presented according to the temperature of kiln tail. You may ask how I control the temperature rising curve. Is there any basis for the temperature rising curve? Professional engineers in Zhengzhou Taida Group will give you detailed answers.
1. For those newly changed refractory bricks and concrete: confirm the temperature and time while materials break away from free water and chemically crystal water. Then, decide corresponding constant temperature zone.
2. If the rotary kiln has to be stopped temporarily without replacing kiln liner, the temperature should be decided according to the amount of raw materials left or kiln coating. It can also be decided according to how long the kiln will be stopped or the season. In order to preventing the cracking of kiln, sometimes materials stored in the kiln can be discharged out as clinker.
3. How to ignite after the kiln is stopped for a little while, the temperature in the kiln is still high. At this moment, the temperature rising time can be shortened according to real situation.
4. In order to protect refractory bricks, operator should follow these two rules: rise temperature slowly and no going back.
How to make a temperature rising curve for rotary kiln? Before starting ignition, technicians should show operators the temperature rising chart in written form. Operators should check the running situation according to the chart. The temperature rising process cannot be too fast and cannot be too slow. Operators should bear in mind that the temperature cannot drop back. Both the air amount into the kiln and the coal amount of added should be controlled well. In a word, the operation process of rotary kiln is a cooperation process. In order to achieve perfect calcining effect, operators are supposed to carry out formal operation.
