Problems solved by technology

[0002] At present, many parts of the cement kiln lining wall are formed by pouring materials at the construction site. Finally, it needs to be cured and baked before it can be put into use. On the whole, the amount of water added in the on-site pouring is random, and the pouring quality defects are large, resulting in defects such as low strength of the castable, poor wear resistance, poor thermal shock stability, and large thermal conductivity. , the outer wall temperature of the kiln cylinder is high, the heat loss is large, the service life is short, and the refractory lining is replaced frequently, which is time-consuming and laborious and affects production

Embodiment 1

[0061] Example 1: Reference Figure 1~Figure 4 , a prefabricated brick for a cross-bar type cement kiln vertical wall, which is a body of a cube structure, one side of the body is provided with a cross-shaped snap-on protrusion a1, and the opposite side of the side where the snap-on protrusion a1 is located is provided with the same cross-shaped the snap-fit ​​groove a2, the snap-fit ​​protrusion a1 and the snap-fit ​​groove a2 are both arc-shaped and compatible in outline;

[0062] The clamping protrusion a1 includes two staggered ridges, which are respectively parallel to the two sides of the rectangular surface, and the clamping groove a2 includes two staggered grooves, respectively penetrating the rectangular surface where it is located.

[0063] One side of the main body is provided with a steel drill slot a3, the surface where the steel drill slot a3 is located is perpendicular to the surface where the clamping projection a1 is located or the surface where the clamping g...

Embodiment 2

[0064] Example 2: Reference Figure 5 , a prefabricated brick for a vertical wall of a cross-bar type cement kiln, the difference from Embodiment 1 is that one side of the prefabricated brick is provided with a stepped card table, and its opposite side is provided with a contour matching it. card table.

[0065] The prefabricated brick preparation process of embodiment 3~embodiment 6 is as follows:

[0066] ①Mixing: Prepare the main ingredients according to the formula, put them in the mixer for stirring, then add the external ingredients and water, and continue to stir. ②Shaping: Add the stirred mixture into the mold, spread it out by the self-weight and surface tension of the mixture, and wipe off the excess mixture on the surface;

[0067] ③Maintenance: Put the mold with the mixture into a constant temperature environment of 25℃, demould after hardening, and leave it for 48 hours after demoulding;

[0068] ④Drying: Place the cured bricks in an electric kiln for drying at...

Abstract

The invention discloses a cross bar type precast brick for cement kiln vertical walls and belongs to the technical field of refractory materials. The precast brick comprises a body of a cuboid structure. One surface of the body is provided with a cross-shaped clamping protrusion. The surface, opposite to the surface provided with the clamping protrusion, of the body is provided with a cross-shaped clamping groove. The clamping protrusion is matched with the clamping groove in contour. The other surface of the body is provided with a steel chisel insertion groove which is provided with a steel chisel insertion hole. The precast bricks are positioned conveniently and accurately. A manufactured heat insulating layer is firm in structure, and can be used for mounting the steel chisel for being welded to a steel-made layer.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a prefabricated brick for a cross-bar type cement kiln vertical wall. Background technique [0002] At present, many parts of the lining wall of the cement kiln are formed by casting materials on the construction site. There are many working procedures. It is necessary to complete the cleaning of the cylinder, the welding of the anchoring nails, the supporting of the formwork, the pouring, the curing, the demoulding and other processes. The pouring is completed. It also needs to be maintained and baked before it can be put into use. Overall, the amount of water added to the on-site pouring is large, and the pouring quality defect is large, resulting in defects such as low strength of the castable, poor wear resistance, poor thermal shock stability, and high thermal conductivity. , The temperature of the outer wall of the kiln cylinder is high, the heat loss is large,...
