New Requirements for Coke Oven Refractories in the Developing Coke Industry

The coke industry has witnessed remarkable growth in recent years, driven by increasing demand from various sectors such as steelmaking. However, this rapid development has also presented new challenges for coke oven refractories. As coke ovens operate under extreme conditions of high temperature, pressure, and chemical corrosion, the refractories used in them need to have excellent performance to ensure stable and efficient operation.

R & D Background and Core Parameters of High - Density Low - Porosity Silica Bricks

In response to the above challenges, high - density low - porosity silica bricks have been developed. These bricks are the result of extensive research and development efforts in the field of refractory materials. The core parameters of these bricks are a porosity of less than 16% and a density greater than 2.38 g/cm³. These strict parameters are the key to their excellent performance.

Technical Advantages of High - Density Low - Porosity Silica Bricks

Denseness

The high density of these silica bricks means they have a more compact structure. This reduces the penetration of corrosive substances such as molten slag and gases into the bricks, thereby significantly improving their corrosion resistance. For example, in some coke ovens with harsh operating environments, traditional silica bricks may show signs of corrosion and damage after a few years of use, while high - density low - porosity silica bricks can maintain their integrity for a much longer time.

Thermal Conductivity

These bricks have excellent thermal conductivity. The high - density structure allows heat to be transferred more efficiently within the bricks. In a coke oven, efficient heat transfer can shorten the coking time. For instance, in some actual production cases, the use of high - density low - porosity silica bricks has reduced the coking time by about 10 - 15%, which greatly improves the production efficiency.

High - Temperature Strength

Under high - temperature conditions in a coke oven, the bricks need to maintain sufficient strength to withstand the pressure and mechanical stress. High - density low - porosity silica bricks have excellent high - temperature strength, which ensures their stability during the coking process. This helps to prevent the deformation and cracking of the coke oven lining, further extending the service life of the coke oven.

Practical Application and Improvement Effect

In practical applications, many coke oven operators have witnessed the significant improvement in the operation efficiency and service life of their coke ovens after using high - density low - porosity silica bricks. For example, in a large - scale steelmaking enterprise's coke oven, after replacing the traditional silica bricks with high - density low - porosity silica bricks, the service life of the coke oven was extended by about 3 - 5 years, and the coking cycle was shortened, resulting in a substantial increase in production volume.

Why High - Density Low - Porosity Silica Bricks are a Wise Choice for Coke Oven Modernization

In conclusion, high - density low - porosity silica bricks are an ideal choice for coke oven modernization. Their excellent performance in terms of denseness, thermal conductivity, and high - temperature strength can effectively solve the problems faced by traditional coke oven refractories. By using these bricks, coke oven operators can achieve more efficient and stable production operations, reduce maintenance costs, and improve overall economic benefits.
