Zero-Expansion Silica Bricks: An Ideal Product for Coke Oven Hot Repair - A Comprehensive Reveal

In the field of coke oven hot repair, finding an ideal product is crucial for enhancing production efficiency and reducing maintenance costs. Zero-expansion silica bricks have emerged as a game-changer, offering a range of benefits that make them the top choice for coke oven hot repair.

The Challenges in Coke Oven Hot Repair

Coke ovens operate under extreme conditions, including high temperatures, thermal cycling, and chemical corrosion. Over time, the refractory lining of coke ovens can suffer from wear and tear, leading to cracks, spalling, and reduced efficiency. Traditional hot repair materials and methods often face limitations, such as poor thermal shock resistance, high expansion rates, and the need for kiln shutdown during repair, which can result in significant production losses.

Introduction to Zero-Expansion Silica Bricks

Zero-expansion silica bricks are primarily made from fused quartz. This unique raw material gives them several outstanding characteristics. They have excellent thermal shock resistance, high strength, and a very low expansion rate. These bricks are specifically designed for hot repair of coke ovens and glass kilns. One of the remarkable features is that they can be used for repair while the kiln is still in operation, eliminating the need for pre - reserved expansion joints.

Comparing with Traditional Hot Repair Materials

Real - World Application Cases

Many coking enterprises have already benefited from using zero-expansion silica bricks. For example, a large - scale coking plant in [Region] replaced its traditional hot repair materials with zero-expansion silica bricks. After the replacement, the frequency of hot repairs decreased by 30%, and the service life of the coke oven lining was extended by 20%. This not only reduced the maintenance cost but also increased the overall production efficiency of the plant.

Technical Knowledge of Zero-Expansion Silica Bricks

The production principle of zero-expansion silica bricks involves a special sintering process that optimizes the crystal structure of fused quartz. The performance indicators of these bricks are also remarkable. They typically have a compressive strength of over 50 MPa, a thermal conductivity of 1.2 - 1.5 W/(m·K), and a porosity of less than 18%.
