The application of refractory materials in nonferrous metallurgy industry is extremely extensive and important, which is mainly reflected in the following aspects:
I. Lining and protection of high-temperature equipment
1. Furnace and furnace wall parts
In the process of nonferrous metallurgy, various high-temperature furnaces such as smelting furnaces, refining furnaces, roasting furnaces, etc. need to use refractory materials as lining. These materials can effectively isolate high temperature, reduce heat loss, and protect the furnace structure from high temperature erosion, thereby ensuring the long-term stable operation of the equipment.
2. Pipes and valves
In the production process of nonferrous metallurgy, pipelines and valves involving high temperature, high pressure, and corrosive media also need to be protected by refractory materials. Refractory materials can resist these harsh conditions, prevent pipelines and valves from deformation and corrosion due to high temperature, and ensure the continuity and safety of the production process.
II. Improve production efficiency and product quality
1. Extend the service life of equipment
High-quality refractory materials can resist the erosion of high temperature, slag and corrosive gases, thereby extending the service life of nonferrous metallurgical equipment. This not only reduces the frequency of equipment replacement and maintenance, but also reduces production costs and improves production efficiency.
2. Maintain a stable furnace temperature and atmosphere
The stability and durability of refractory materials help maintain the stability of furnace temperature and atmosphere, providing good environmental conditions for non-ferrous metallurgical reactions. This is conducive to the smooth progress of the reaction and improves the quality and output of the product.
III. Adapting to complex process requirements
1. Application of various types of refractory materials
Different types of refractory materials need to be selected according to the different requirements of non-ferrous metallurgical processes. For example, for equipment that needs to withstand extremely high temperatures, high-purity alumina, silicon carbide and other refractory materials can be selected; while for equipment that needs to resist highly corrosive media, magnesia-chrome bricks and high-alumina bricks with excellent corrosion resistance can be selected.
2. Development of customized refractory materials
With the continuous progress and development of non-ferrous metallurgical processes, higher requirements are also placed on refractory materials. In order to meet these requirements, refractory manufacturers need to continue to innovate and develop customized refractory materials. These materials can be designed and produced according to specific process conditions and equipment requirements to better adapt to complex process requirements.
