Abstract

The invention discloses a method for constructing kiln mouth refractory materials of a rotary cement kiln. The method for constructing the kiln mouth refractory materials of the rotary cement kiln comprises the following steps that 1) the boundary dimension of prefabricated parts is designed according to a kiln mouth structure, and then kiln mouth prefabricated parts are manufactured; and 2) a kiln mouth is cleaned, and then the plurality of kiln mouth prefabricated parts are mounted at the kiln mouth, so that the kiln mouth prefabricated parts are piled into a ring shape at the kiln mouth. According to the method for constructing the kiln mouth refractory materials of the rotary cement kiln, and the service life of the kiln mouth refractory materials can be effectively prolonged.

Description

technical field [0001] The invention relates to a cement rotary kiln, in particular to a method for constructing a kiln mouth refractory of a cement rotary kiln. Background technique [0002] The front kiln mouth is the discharge port and also the cooling part. On the one hand, the front kiln mouth bears the heat load and scouring action from the high-temperature clinker in the firing zone, and on the other hand, it receives the action of high air volume pressure from the cooler, and the temperature changes repeatedly from 1100°C to 1400°C. This requires that refractory materials must have good high temperature wear resistance, erosion resistance and thermal shock resistance. [0003] At present, the grade of castables for kiln mouths is very high, and the construction methods are mostly traditional methods: kiln mouth welding anchors, supporting molds and pouring refractory materials. In the construction process of this method, due to the inability to effectively control ...
