First of all, in order to better guarantee the air permeability of the surface of the ventilating brick, it needs to be made in a mode of steel infiltration in the ventilation channel, and in this process, we need to ensure the value of its steel infiltration In order to control the relative material of the ventilated brick, the wetting angle of the ventilated brick can be well controlled with the molten steel; in addition, the performance of the ventilated brick will be affected by the environment in use. The strong scouring of the molten steel properties, so that the material of the brick body is required to have high enough structural properties, and high-temperature mechanics and other related properties during the production.

It is reported that this high-performance לבנה נושמת is applied in an intermittent mode during use. Therefore, all materials of the brick body need to have strong thermal shock resistance under the action of acute cold and warm. Performance and strong anti-stripping performance, etc. It is precisely because of such good product performance that in the later use and maintenance, it needs to perform oxygen-burning cleaning action, and finally improve the oxidation resistance of the brick surface material, so that it can be used in the later production. Better improve the service life of its products.

Therefore, in order to better meet the various properties required in the process of use, in the production of this kind of craft brick, it is necessary to effectively reduce the content of its fine powder and increase the content of the required neutral particulate matter. Relevant ratio. At the same time, its raw materials need to use plate-shaped corundum profiles, as well as corundum profiles such as fused zirconium as the aggregates, while using a micronized raw material such as activated alumina, and high purity High-performance fused spinel, and a unique chromium oxide green and other profile materials, to make the matrix ratio. In this process, we should pay attention to the proportion of cement, chromium steel and other materials in this process, which should be less than other corundum-type materials.

This is mainly due to the fact that these raw materials have the same physical and chemical properties, such as high fire resistance, and strong thermal shock stability. During use, they also have strong resistance to slag erosion. It has low creep properties and low heat shrinkage performance to show the application performance of the air-permeable bricks in the relevant temperature where the load performance is relatively soft.
