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. Only by controlling the ventilation bricks can the relevant materials of the ventilation bricks be able to control the wetting point of view with the molten steel. The strong erosion of the molten steel function, so that the material of the brick body is required to have a sufficiently high structural function and related functions such as high temperature mechanics in the manufacture.

It is reported that this kind of high-function breathable brick is used intermittently in the process of use, so under the effect of acute heating and cooling, all the materials of the brick body need to have strong thermal shock resistance function and strong anti-shedding function, etc. Because of such good product performance, in the later use and maintenance, it is necessary to carry out oxygen burning cleaning effect, and finally improve the anti-oxidation function of the external surface material of the brick. 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 add the required 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 refractory properties, strong thermal shock stability, etc., and also have strong resistance to slag corrosion during use It has low peristaltic properties and low heat shrinkage function to show the application function of its breathable bricks at the relevant temperature where the load function is relatively softened.
