The Background of High - Density and Low - Porosity Silica Bricks in the Coke Industry

In the dynamic landscape of the coke industry, the requirements of coke ovens for refractory materials are constantly evolving. As production scales expand and technological advancements continue, the performance of refractory materials directly impacts the efficiency, quality, and lifespan of coke ovens. The high - density and low - porosity silica bricks have emerged as a revolutionary solution to meet these increasing demands. If you miss this high - density and low - porosity silica brick, you may miss the opportunity to enhance the performance of your coke oven.

Outstanding Performance of High - Density and Low - Porosity Silica Bricks

This high - performance refractory material is specifically designed to meet the stringent requirements of coke ovens. Its three major outstanding properties are high density, high thermal conductivity, and high compressive strength at high temperatures.

Let's compare it with ordinary silica bricks. Ordinary silica bricks usually have a density of about 2.30 - 2.35 g/cm³ and a porosity of around 20 - 25%. In contrast, the high - density and low - porosity silica bricks have a density greater than 2.38 g/cm³ and a porosity of less than 16%. The higher density means more compact internal structure, which can effectively resist the erosion of high - temperature flue gas and chemical substances. The high thermal conductivity, up to 1.5 - 2.0 W/(m·K) compared to 1.0 - 1.3 W/(m·K) of ordinary silica bricks, allows for faster heat transfer within the coke oven, improving the heating efficiency. And the high compressive strength at high temperatures, which can reach over 50 MPa at 1400°C while ordinary silica bricks may only reach 30 - 40 MPa, ensures the stability of the coke oven structure under high - temperature and high - pressure conditions.

Positive Impact on Coke Ovens with High - Density Silica Bricks

Data and real - world cases clearly demonstrate the advantages of high - density and low - porosity silica bricks. A coke production plant in [Location] replaced its original ordinary silica bricks with high - density and low - porosity silica bricks. After the replacement, the quality of coke products increased by 10%. The lifespan of the coke oven was extended from the original 10 - 12 years to more than 15 years. Moreover, the coking time was significantly shortened. Previously, it took about 18 - 20 hours for a coking cycle, but after using this high - performance silica brick, the coking cycle was reduced to 15 - 16 hours, greatly improving production efficiency.

Strict Standards for Product Quality

To ensure the excellent performance of coke ovens, the high - density and low - porosity silica bricks adhere to strict standards. The finished product has a porosity of less than 16% and a density greater than 2.38 g/cm³. These strict standards guarantee that the product can effectively withstand the harsh working environment of coke ovens, such as high - temperature flue gas erosion, chemical corrosion, and mechanical stress.

How to Judge if the Product Meets Your Coke Oven Requirements

As a purchaser, you may wonder how to determine if this high - density and low - porosity silica brick is suitable for your coke oven. First, you need to consider the specific requirements of your coke oven, such as temperature range, production scale, and the type of raw materials used. You can compare the performance parameters of the product, including density, porosity, thermal conductivity, and compressive strength at high temperatures, with your actual needs. Second, you can ask for samples from the supplier to conduct on - site tests and evaluations. Third, you can also refer to the experience and feedback of other users in the industry.
