The refractoriness of silicon brick is one of its most important performance indexes, which has a far-reaching impact on industrial application. Refractory refers to the temperature at which refractories resist softening or melting at high temperature, which directly determines the stability and service life of silicon bricks in high temperature environment. The following are the specific effects of refractoriness on the industrial application of silicon bricks:

I. Stability in high temperature environment

Advantages of high fire resistance: the fire resistance of silicon brick is usually between 1690℃ and 1750℃, which means that it can maintain the stability of structure and performance at extremely high temperature. For example, in high temperature equipment such as coke oven, glass kiln, hot blast stove, etc., silicon bricks can withstand high temperature for a long time without softening or melting.

Practical application: In coke oven, the temperature of furnace bottom and furnace wall may be as high as 1300℃~1400℃, and the high refractoriness of silicon brick ensures its long-term stable operation in these high temperature areas. If the fire resistance is insufficient, the brick may soften or even melt at high temperature, which will damage the furnace structure and affect the normal operation of the equipment.

II. Extending the service life of equipment

Relationship between refractoriness and service life: Silicon bricks with high refractoriness can keep stable performance for a longer time in high temperature environment, thus prolonging the service life of equipment. High refractoriness means that silicon bricks are not easy to change chemically and physically at high temperature, which reduces the damage caused by high temperature erosion.

Practical application: In glass kilns, silica bricks are used for furnace bottom and furnace wall, and their high fire resistance can withstand the high temperature environment during glass melting. If the fire resistance is insufficient, the brick body may be eroded or damaged in a short time and need to be replaced frequently, thus increasing the maintenance cost and downtime.

III. Improving production efficiency

Reduce downtime: Silicon bricks with high fire resistance can reduce the number of downtime and maintenance caused by high temperature damage. In the continuous production of industrial equipment, such as coke oven and glass kiln, the downtime of the equipment directly affects the production efficiency. Silicon bricks with high fire resistance can ensure the long-term stable operation of equipment, thus improving production efficiency.

Practical application: In the hot blast stove, silica brick is used as furnace lining, and its high fire resistance can withstand the impact of high temperature airflow. If the fire resistance is insufficient, the brick body may be damaged in a short time, leading to shutdown and maintenance, which will affect the normal operation of the hot blast stove.

IV. Energy-saving effect

Reduce heat loss: Silicon bricks with high fire resistance can better retain heat in high temperature environment and reduce heat conduction loss through the brick body. This not only helps to improve the thermal efficiency of equipment, but also reduces energy consumption.

Practical application: In tunnel kiln, silica brick is used as furnace lining, and its high fire resistance can effectively reduce heat loss and improve the thermal efficiency of kiln. If the fire resistance is insufficient, the heat may be quickly dissipated through the brick, leading to energy waste.

V. Adapting to complex working conditions

Double resistance of high temperature and chemical erosion: in many industrial applications, refractories not only have to withstand high temperature, but also resist chemical erosion. Silicon bricks with high fire resistance can maintain good chemical stability at high temperature and resist corrosion by acid slag, alkaline slag and other chemical media.

Practical application: In nonferrous metal smelting furnace, silicon brick is used as furnace lining, and its high refractoriness and good corrosion resistance can effectively resist the corrosion of high-temperature slag and ensure the long-term stability of furnace lining.

VI. Impact on industrial equipment design

Optimize the structure of equipment: The silica brick with high fire resistance allows industrial equipment to operate at higher temperature, thus optimizing the design structure of equipment. For example, it can reduce the thickness of furnace lining, reduce the weight of equipment and improve the thermal efficiency of equipment.

Practical application: In the design of modern coke oven, due to the high refractoriness of silicon brick, the thickness of furnace wall can be appropriately reduced, thus improving the thermal efficiency and service life of furnace body.

VII. Impact on industrial costs

Reduce maintenance cost: Silicon bricks with high fire resistance can reduce the frequency of maintenance and replacement caused by high temperature damage, thus reducing maintenance cost. Although the price of silica bricks with high fire resistance may be higher, in the long run, its comprehensive cost-effectiveness is very significant.

Practical application: In the glass kiln, the use of silica bricks with high refractoriness can reduce the number of downtime due to high temperature erosion, thus reducing maintenance costs and downtime losses.

VIII. Summary

The high refractoriness of silicon brick is one of its core advantages in industrial application. It directly determines the stability, service life, production efficiency, energy saving effect and adaptability to complex working conditions of silicon brick in high temperature environment. Silicon brick with high fire resistance can significantly improve the operation efficiency and economy of industrial equipment, and it is an indispensable and important material for modern high-temperature industry.
