What are the production process and control points of breathable bricks

Breathable bricks play an insignificant position in my country's steelmaking industry. Argon gas can be injected into the steel through the breathable bricks. During the selection process of the breathable bricks, the temperature of the water inside the steel can be adjusted, and the molten steel can be stirred to make all the components in the entire molten steel evenly distributed. Distributed in every place, at the same time, it can also help the existing molten steel to remove internal impurities, so that all the internal impurities in it will float up, which is beneficial to all the impurities.

In the production process of the breathable brick, the materials are first prepared according to the formula, and then the prepared ingredients are stirred according to some relevant stirring rules. After stirring, all the material preparation procedures can be completed, and then all the materials are poured into the mold that has been predetermined by itself. Among them. Vibration can then be carried out. After the vibration, the breathable brick itself will be formed, and maintenance and demoulding will be carried out to obtain the brick core of the breathable brick. After the brick core is formed, a series of processes such as drying and firing will be carried out. , to be stocked.

When selecting the ingredients for the production of air-permeable bricks, it is necessary to ensure that the ambient temperature of all the ingredients in the mixing plant can be stirred. .Breathable bricks must be stirred by a mixer in this process. The mixer gradually increases all the materials inside, first increase the particles and then add the small particles, first add the aggregate and then add the powder.

Each time the material of the breathable brick is synthesized, it is necessary to increase the moisture according to a fixed proportion. The mixer is a 140 mixer, which can stir an average of 400kg of breathable brick material each time. It is divided into 2 parts, one part is dry mixing, and the other is wet mixing Stirring. Under normal conditions, the dry stirring is 3 minutes, and the stirring time is 8 minutes. After all the stirring is completed, it should be observed to see if the material produced is segregated.

The production date, shift serial number, etc., should be recorded on each of the produced breathable bricks, so that each brick can be specially recorded, which is convenient for information inquiry. After that, all the breathable bricks produced must pass through Adjustment, the work after adjustment includes basic treatment such as hanging feet, scarring, repairing, etc. Then it is dried, and the process of drying and firing is strictly carried out in accordance with the company's guidelines. After drying, it can be inspected if there is no problem, and then cleaned and put into storage. .
