In the glass kiln project, if you want to reach the designed service life or avoid pollution to the glass solution, you must have a comprehensive understanding of the external quality and internal quality of the fused brick, and understand its performance and weak points: which parts can be flawed and which parts must be perfect.

The following is a brief introduction to the special parts of the wall of Baisheng glass furnace:

First, the appearance quality, the corner brick, kiln cut brick, bubbling brick and flowing hole brick in the pool wall part are generally 41 #. The assembly gap with the adjacent brick should be strictly required, and the assembly gap should be no more than 0.5mm, and the shrinkage cavity is not allowed at the bottom of the brick. The surface pores larger than ? 2 mm are not allowed to exceed 12 per cubic meter, and the color of the brick body is yellow in white, bubbling and bubbling. These requirements are very critical, and failure to do so will affect the service life of brick materials.

Second, the internal quality, 1. Judging the impurities in the fused brick from the color of the brick body, or judging whether the brick body with high carbon content is blue, strictly putting an end to the use of this brick will double the service life of the kiln. 2. If the surface of the brick is blue, there is a great possibility that there is iron in it, which comes from the falling off of the iron brazing part during the flat material or the exhaust in the production process, and other factors. This kind of imaginary brick is also to put an end to the use. 3. The proportion of glass phase must be strictly controlled. If the glass phase exceeds the standard, the service life of the kiln will be reduced and the glass melt will be polluted when the glass phase precipitates in a large amount at high temperature.

Three, the above briefly explain a few points, there are many factors that need attention. In fact, in the process of using glass kiln, there will be some problems, which will have a great component of brick quality. Therefore, when purchasing fused bricks, we must know something about fused bricks, so as not to be passive in the end.
