cement kiln

With the development of various kiln-type cement kiln, as well as large-scale cement kiln, the requirements for the furnace refractory material also occurred a series of changes.
The effect of the refractory used in the cement rotary kiln is to protect the kiln from the hot material in the kiln (the material temperature is usually around 1450 ° C) or the flame (1600–1700 ° C); reduce the radiation and convection heat loss. Kiln shot in the cement kiln to withstand a variety of physical and chemical effects, such as in the kiln rotation process subjected to periodic thermal shock; due to the rotation of the kiln to withstand mechanical stress; also by the calcined material wear, especially the firing zone (Vertical kiln for high temperature zone) chemical erosion of materials, etc., working conditions are very bad.
The operation period of various cement rotary kilns is mainly determined by the quality of the refractory material used in the kiln, especially the rotary kiln (including the Li Boer kiln, the suspension preheating kiln and the kiln kiln) The quality of abrasion resistant materials. In order to ensure the long-term safe operation of the kiln, to reduce the planned kiln maintenance time, improve the kiln operation rate, we must study the requirements of refractory materials and refractory performance and quality.
Large-scale kiln burning zone and excessive belt refractory material to withstand high heat load and yield load. According to some large and small and medium-sized suspension preheating kiln statistics, found kiln cross-sectional area of ​​the heat load and production load, in the large kiln than in the small to be more than double. Therefore, to burn with refractory life is basically in line with the kiln square inversely proportional to the square.
