How to improve the service life of breathable bricks

In the process of making the breathable brick, the materials should be prepared according to the formula, and then the prepared ingredients should be stirred according to some relevant stirring systems. After stirring, all the preparation procedures can be completed, and then all the materials are poured into the predetermined mold. .Then it can be vibrated. After the vibration, the breathable brick itself will be formed. After Z, the core of the breathable brick is obtained by demoulding. After forming, the brick core is dried and fired, and then put into storage.

In the bottom blowing asymmetric air supply mode, 2 groups of breathable bricks work alternately in production. Generally speaking, when the 2 groups of breathable bricks play a role, the life of the ladle can be greatly improved. When the breathable brick manufacturer and the ladle are not very large, the ventilation There is no big problem in the large-flow gas supply of bricks. In comparison, this method will increase the cost, but it is not enough relative to the economic benefits generated by the promotion effect and the improvement of the package age.

The splitting method of replacing the hollow core with breathable bricks. After the hollow core alarms, the buffer brick under the breathable brick is broken, and the hollow core is replaced with a new one. This method can achieve the purpose of making full use of other refractory materials in the bag and prolonging the life of the bag.

By controlling reasonable bottom blowing parameters and regular maintenance, not only the life of the ladle can be improved, but also the metallurgical effect can be maintained. During the use of the breathable brick, when the bottom blowing pressure is too high, the molten steel will violently tumble, resulting in the occurrence of 2 Secondary oxidation; if the pressure is too low, the molten steel cannot be blown out, resulting in the failure of bottom blowing and affecting the metallurgical effect. In addition, long-term neglect of maintenance of the bottom blowing device may lead to air leakage, which not only causes the loss of bottom blowing gas, increases production costs, and even causes bottom blowing pressure If it is too low, it will affect the production process.

In addition to the above methods, there are many ways to improve the service life of breathable bricks, such as changing the type of bricks of breathable bricks.
