As an important industrial site for converting coal into coke, the coking plant has a specific demand for refractories. The following is an introduction to refractory materials for coking plants:
I、Importance
In the production process of the coking plant, refractory materials play a key role. The coke ovens and chemical production and recovery equipment of the coke plant operate under high temperature, high pressure and corrosive environment, and refractory materials can provide effective protection for these equipment to ensure the safety, stability and efficiency of production.
II、main types
1. Silicon brick: has good acid corrosion resistance and high refractoriness, suitable for high temperature parts of coke oven, such as furnace top, combustion chamber, etc. The silicon brick can withstand the high temperature and acid gas erosion in the coking process to ensure the stability of the furnace structure.
2. Clay brick: The price is relatively low, with good thermal stability and mechanical strength. In the coke plant, clay bricks are often used in the furnace wall and bottom of the coke oven, as well as the lining of some auxiliary equipment.
3. High aluminum brick: high refractoriness, good thermal shock resistance, suitable for parts with large temperature changes. In the coke oven regenerator, riser and other parts of the coke plant, high alumina bricks can effectively resist thermal shock and wear.
With the technological progress of the coking industry and the improvement of environmental protection requirements,
Refractory materials for coking plants will develop in the following directions in the future:
1. High performance: Research and development of refractories with higher refractoriness, better erosion resistance and thermal stability to adapt to more demanding production environments.
2. Energy saving and environmental protection: The development of thermal insulation refractory materials with low thermal conductivity to reduce heat loss and improve energy efficiency. At the same time, pay attention to the environmental performance of refractory materials, reduce environmental pollution.
3. Intelligent: The use of advanced testing technology and data analysis means to real-time monitoring and evaluation of the use of refractory materials, to achieve intelligent management and maintenance.
4. Customization: According to the production characteristics and needs of different coking plants, provide personalized refractory solutions to improve the suitability and service life of refractory materials.
