Problems solved by technology

[0003] Production practice shows that this method has the following disadvantages: 1) The lifting brick is composed of several bricks and cannot form a whole. The kiln causes temperature changes in the kiln, and the expansion and displacement of the lining refractories (including lifting bricks) in the annular area and the longitudinal area of ​​​​the kiln are uneven, which may easily cause a piece or a ring of bricks to fall off and affect the life of the entire lining refractory

Embodiment Construction

[0021] A new type of refractory-lined lifting brick for rotary kiln, see Figure 2 and Figure 3, cast refractory castable 2 on a metal structure frame according to the required specifications and sizes, see Figure 4, Figure 5, metal structure frame It includes the channel steel 5 used to weld the lifting brick on the rotary kiln shell 6 and the anchor piece 4 welded on the channel steel so that the channel steel 5 and the refractory castable 2 are integrated, as well as the channel steel 5 for welding It is an inlay rod 3 for inlaying two lifting bricks 1 together in the length direction of the rotary kiln. As shown in Figure 6, the anchor is made of heat-resistant stainless steel and is in the shape of a "V". The inlaid rod 3 is made of common material round steel. The lifting part of the lifting brick is poured into a square cone shape, which can reduce the erosion and wear of the material on the corners of the brick. The lifting brick formed by one-time casting with refract...

Abstract

The invention relates to a novel structure of rotary kiln lining refractory spreading brick. Its characteristic: there is metal structural frame in the spreading brick, the castable refractory. Is poured at the metal structural frame to form spreading brick and is welded on the rotary kiln drum body by the metal structural frame, in the rotary kiln length direction, inter-adjacent spreading bricks are connected to form one piece as a whole by mosaic rod on the metal structural frame.

Description

technical field [0001] The invention relates to a refractory material lifting brick lining a rotary kiln for calcining refractory materials, lime, cement and other materials. Background technique [0002] When the lining refractory material of the feed end (preheating section) of the existing rotary kiln used for calcination of refractory materials, lime, cement and other materials is built, there are several protruding parts on the annular section ( See Figure 1), the bricks used for the masonry of these protruding parts are called lifting bricks. Usually, the material and brick structure of these bricks are not much different from other bricks. They are wedge-shaped bricks, but the width and size of the bricks are different. Its masonry method is no different from other bricks, and generally adopts traditional wet or dry masonry methods. [0003] Production practice shows that this method has the following disadvantages: 1) The lifting brick is composed of several bricks...
