What are the requirements for manufacturing materials of breathable bricks?

First of all, in order to better ensure the permeability of the surface of the breathable brick, it needs to be manufactured in the form of steel infiltration in the ventilation channel, and in this process, we need to ensure the value of its steel infiltration. The control of the ventilation bricks can make the relevant materials of the ventilation bricks can control the moisture point of the molten steel. Due to the intense erosion of the molten steel function, the material of the brick body is required to have sufficiently high structural functions and related functions such as high temperature mechanics in the manufacture of bricks.

It is reported that this kind of high-function breathable brick is applied intermittently during the application process. Therefore, under the effect of acute heating and cooling, all materials of the brick body need to have strong thermal shock resistance. Because of such good product performance, in the later use and maintenance, it is necessary to carry out burning oxygen cleaning effect, and finally improve the anti-oxidation function of the brick surface material. In the later production effect, it can better improve the service life of its products.

Therefore, in order to better meet the various functions required in the application process, in the manufacture of this kind of craft brick, it is necessary to effectively reduce the content of its fine powder and increase the required amount of medium particulate matter. At the same time, in the manufacturing process, the raw materials are required to use plate-shaped corundum profiles, as well as fused zirconium and other corundum profiles as the aggregates produced, and a micro-powder material such as activated alumina is used. , as well as high-purity functional fused spinel, and a unique type of chrome oxide green and other materials to make the matrix ratio. In this process, we should pay attention to its cement chrome steel and other materials in this process. The proportion of the sintered alumina should be less than that of other corundum-type elements.

This is mainly because these materials themselves have the same physical and chemical properties, such as their high fire resistance and strong thermal shock stability, etc., and also have strong resistance to slag corrosion during use It has low activity and small heat shrinkage function to show its application function of breathable bricks at the relevant temperature where the load function is relatively softened.
