Non-ferrous metal refractories are refractory materials specially designed for high-temperature environments where non-ferrous metals are processed and smelted. The following are the main characteristics of non-ferrous metal refractories:
1. High temperature resistance: non-ferrous metal smelting process needs to withstand extremely high temperature, and non-ferrous metal refractories have excellent high temperature resistance. They maintain a stable structure and strength and are not easily damaged by thermal expansion, corrosion or thermal stress.
2. Good thermal conductivity: Non-ferrous metal refractories usually have good thermal conductivity, which can quickly conduct heat and disperse temperature. This is very important for uniform heating and control of temperature distribution to ensure the stability and efficiency of the non-ferrous metal smelting process.
3. Corrosion resistance: non-ferrous metal refractories exhibit good corrosion resistance when in contact with non-ferrous metals and their salts. They are resistant to attack and erosion by metal oxides, molten salts and other aggressive media.
4. Mechanical strength: Non-ferrous metal refractories usually have high mechanical strength and can withstand physical pressure and mechanical stress during the smelting process. This allows them to maintain structural integrity at high temperatures and resist effects from elements such as vibration, shock and mechanical manipulation.
5. Stable size and shape: Non-ferrous metal refractories usually have good size and shape stability under high temperature conditions. This means they will not visibly deform or break after prolonged use, maintaining a stable geometry and size.
6. Thermal shock stability: Non-ferrous metal refractories usually have good thermal shock stability and can withstand thermal stress caused by rapid temperature changes. They reduce the occurrence of thermal shock cracks and fractures, improving refractory life and performance.
7. Good conductivity: Non-ferrous metal refractory materials usually have good conductivity, which helps to maintain a constant current distribution and electromagnetic field. This is very important for electrolytic processes or non-ferrous metal smelting where electromagnetic stirring is required.
In general, non-ferrous metal refractories have the characteristics of high temperature resistance, good thermal conductivity, corrosion resistance, high mechanical strength, stable size and shape, thermal shock stability, and good electrical conductivity. According to different non-ferrous metal smelting processes and application requirements, suitable non-ferrous metal refractory materials can be selected to improve production efficiency and protect equipment.
