Exploring the Core Technical Knowledge of High-Density, Low-Porosity Silica Bricks

In the development of the coke industry, coke ovens have long faced challenges related to refractory materials. Early on, traditional refractory materials struggled to meet the harsh working conditions of coke ovens, such as high temperatures, strong chemical corrosion, and mechanical stress. This situation has spurred the research and development of high - density, low - porosity silica bricks.

Product Characteristics and Comparison with Traditional Silica Bricks

High - density, low - porosity silica bricks possess several outstanding characteristics. Firstly, their high density and low porosity result in fewer pores, which enhances their resistance to chemical corrosion and mechanical wear. Compared with traditional silica bricks, the density of high - density, low - porosity silica bricks can reach up to 2.3 g/cm³, while traditional silica bricks usually have a density of around 2.0 - 2.2 g/cm³.

In terms of thermal conductivity, high - density, low - porosity silica bricks have excellent high - thermal conductivity. The thermal conductivity can reach 1.5 - 2.0 W/(m·K) at high temperatures, which is significantly higher than that of traditional silica bricks. This high thermal conductivity allows for faster heat transfer in the coke oven, improving the efficiency of the coking process.

Moreover, these bricks have high temperature - resistance and high compressive strength. They can withstand high temperatures of up to 1600°C without significant deformation, and their high - temperature compressive strength can reach over 50 MPa, far exceeding the performance of traditional silica bricks.

Product Performance Data and Cases

Actual tests and cases have demonstrated the significant advantages of high - density, low - porosity silica bricks in improving coke oven quality, extending service life, and shortening coking time. In a certain coke plant, after replacing traditional silica bricks with high - density, low - porosity silica bricks, the coke oven's service life was extended from the original 15 years to over 20 years. At the same time, the coking time was shortened by about 10%, from an average of 18 hours to 16.2 hours, greatly improving production efficiency.

Cost - Benefit Analysis from the Customer's Perspective

From the customer's perspective, although the initial investment in high - density, low - porosity silica bricks is relatively higher than that of traditional silica bricks, the long - term benefits are significant. The extended service life of the coke oven reduces the frequency of repairs and replacements, saving a large amount of maintenance costs. The shortened coking time increases production capacity, bringing more economic benefits. Many customers have given positive feedback after using these bricks. One customer said that the use of high - density, low - porosity silica bricks has improved their overall production efficiency by about 15% and reduced maintenance costs by about 20%.

Decision - Making Suggestions for Customers

When considering whether to use high - density, low - porosity silica bricks, customers can evaluate from the following aspects. First, assess the current condition of the coke oven, including its age, existing problems, and future production plans. Second, calculate the long - term cost - benefit based on the data provided above. Finally, consider the reputation and after - sales service of the product supplier.
