Compared with other refractories, Shi Ying Shuikou brick has many obvious advantages, which make it perform well in high temperature applications such as steel industry. The following are the main advantages of Shi Ying Shuikou brick and its comparison with other refractories:

I. High purity and chemical stability

The main component of Shi Ying Shuikou brick is silicon dioxide (SiO₂), and its purity is usually above 99.2%. This high purity makes it have excellent chemical stability and can resist the erosion of acidic and alkaline slag. In contrast, other refractory materials, such as silicon carbide brick, have good corrosion resistance, but their thermal conductivity is high, which may lead to the thermal shock stability is not as good as that of Shi Ying Shuikou brick.

II. Low thermal expansion coefficient and thermal shock resistance

The thermal expansion coefficient of Shi Ying Shuikou brick is very low, only 0.54× 10℃ (0 ~ 1000℃), which makes it have excellent thermal shock resistance in high temperature environment. In contrast, the thermal expansion coefficient of ordinary silicon brick is high, and it is easy to crack when the temperature changes. This characteristic of Shi Ying Shuikou brick enables it to withstand frequent temperature changes during continuous casting and reduce the damage caused by thermal stress.

III. High strength and wear resistance

Shi Ying Shuikou brick has high mechanical strength, the cold pressing strength can reach more than 45 MPa, and the bending strength can reach more than 25 MPa. It has high hardness and good wear resistance, and can effectively resist the erosion of molten steel. In contrast, some traditional refractory materials, such as clay bricks and high-alumina bricks, have certain strength, but their performance is not as good as that of Shi Ying Shuikou bricks in high temperature and high wear environment.

IV. Low thermal conductivity

The thermal conductivity of Shi Ying Shuikou brick is low, usually less than 0.6 W/m k. This feature enables it to effectively insulate heat in high temperature environment, reduce heat loss and reduce energy consumption. In contrast, the silicon carbide brick has higher thermal conductivity and better wear resistance, but it is not as good as Shi Ying Shuikou brick in thermal insulation.

V. Anti-erosion and anti-scour performance

Shi Ying Shuikou brick has excellent erosion and erosion resistance, which can effectively resist the erosion of molten steel and slag. In the continuous casting process, Shi Ying nozzle brick can reduce the accumulation and deposition of high melting point oxides and reduce the risk of nozzle blockage. In contrast, some other refractories, such as graphite nozzle bricks, have good erosion resistance, but their erosion resistance is relatively weak.

VI. Long service life

The long service life of Shi Ying Shuikou brick is one of its remarkable advantages. Because of its high purity, low thermal expansion coefficient and excellent corrosion resistance, the service life of Shi Ying Shuikou brick is usually longer than other refractories in high temperature environment. This not only reduces the replacement frequency, but also reduces the maintenance cost.

VII. Environmental Protection and Economy

The production process of Shi Ying Shuikou brick is relatively environment-friendly, and it will not release harmful substances during use. In addition, although its initial cost may be slightly higher than that of some traditional refractories, its long life and low maintenance cost make its comprehensive cost lower in the whole life cycle.

VIII. Summary

Shi Ying Shuikou brick has obvious advantages in high purity, low thermal expansion coefficient, thermal shock resistance, high strength, low thermal conductivity, corrosion resistance and scour resistance. These characteristics make it perform well in the continuous casting process of steel industry. Compared with other refractories, Shi Ying Shuikou brick can effectively improve production efficiency, reduce maintenance costs, and ensure the long-term stable operation of equipment.
