A brief introduction to what materials are needed for ventilation bricks

First of all, in order to better ensure the air permeability of the surface of the breathable brick, it needs to be made 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 raw materials of the ventilation bricks can well control the wetting point of view with the molten steel; in addition, the ventilation bricks in the functional use will be subject to environmental problems. The intense erosion of some molten steel functions, and then the material of the brick body is required to have sufficiently high structural functions and related functions such as high temperature mechanics.

It is reported that this kind of high-function breathable brick is used intermittently during use, so under the action 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 function, and then in the later use and protection, it needs to carry out burning oxygen cleaning effect, and finally improve the anti-oxidation function of the brick surface raw materials, Let it in the later production role, can better improve the service life of its products.

Therefore, in order to better meet the various functions required in the use process, in the production 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 production process, it is necessary to use plate-shaped corundum profiles, as well as fused zirconium and other corundum profiles as aggregates, and use a micro-powder material such as activated alumina. , as well as high-purity functional fused spinel, and a unique raw material such as chrome oxide green, to carry out matrix ratio. In this process, we should pay attention to its cement chrome steel and other raw materials here The ratio in the process should be less than that of other corundum-type elements.

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