Focus on Zero-Expansion Silica Bricks: How to Boost Coke Oven Hot Repair Efficiency for Coking Enterprises

In the coking industry, coke oven hot repair is a crucial task that directly affects the production efficiency and cost of coking enterprises. However, traditional hot repair methods and materials often face various problems.

Problems in Coke Oven Hot Repair and Limitations of Traditional Methods

Traditional hot repair materials usually have poor thermal shock resistance and high expansion rates. When used for coke oven repair, they may cause cracking and peeling due to temperature changes, resulting in short repair life. In addition, traditional repair methods often require the coke oven to stop production, which not only affects the normal production schedule but also incurs high downtime costs. Statistics show that the average downtime for traditional coke oven hot repair is about 3 - 5 days, and the resulting production loss can reach hundreds of thousands of dollars.

Introduction to Zero-Expansion Silica Bricks

Zero-expansion silica bricks are an ideal solution to these problems. They are mainly made of fused quartz, which endows them with excellent properties. These bricks have good thermal shock resistance, high strength, and a very low expansion rate. As shown in the following table:

Advantages of Zero-Expansion Silica Bricks over Traditional Materials and Methods

Compared with traditional hot repair materials and methods, zero-expansion silica bricks have significant advantages. Firstly, they can be used for repair during the operation of the coke oven without the need for shutdown. This greatly reduces the impact on production and saves a lot of downtime costs. Secondly, their long service life can effectively reduce the frequency of repairs, thereby reducing maintenance costs. According to practical experience, the use of zero-expansion silica bricks can reduce maintenance costs by about 30% - 40%.

Actual Application Cases

Many coking enterprises have already benefited from the application of zero-expansion silica bricks. For example, a large coking enterprise in [Region] used zero-expansion silica bricks for coke oven hot repair. After the repair, the service life of the coke oven increased from the original 1 - 2 years to more than 3 years, and the production efficiency increased by about 15%. Another enterprise reduced the number of hot repairs from 3 - 4 times a year to 1 - 2 times, significantly reducing maintenance costs.

Professional Knowledge of Zero-Expansion Silica Bricks

The production principle of zero-expansion silica bricks is based on the unique physical and chemical properties of fused quartz. By a special production process, the raw materials are processed into bricks with stable performance. The main performance indicators include thermal shock resistance, compressive strength, and expansion rate, which are all crucial for coke oven hot repair.
