根据国外资料介绍了有关防止直接还原回转窑结圈的操作成功经验,结圈机理,影响回转窑结圈的因素等。由资料表明,这一技术日趋成熟,通过有效地控制窑内温度,选好工艺设备,重视原料和还原煤的性能研究。回转窑是可以获得持续、稳定地运转。 Based on foreign materials, the successful experiences of preventing the knot ring of direct reduction rotary kiln, the knot ring mechanism and the factors that affect the knot ring of rotary kiln are introduced. The data show that this technology is maturing, through the effective control of the kiln temperature, the selection process equipment, emphasis on raw materials and the performance of coal reduction. Rotary kiln can be sustained, stable operation.
