Description
The nozzle brick is crafted from high-purity raw materials, using vibration casting and low-temperature baking techniques. It boasts several advantages, including exceptional thermal strength, resistance to thermal shock, corrosion, and erosion, as well as thermal repair capabilities.
Key Features and Benefits:
- Exceptionally high refractoriness.
- Endurance at high temperatures.
- Effective corrosion resistance.
- Strong resistance to spalling and wear.
- Impressive thermal shock resistance.
- High mechanical strength.
- Low creep rate at high temperatures.
- Remarkable volume stability at elevated temperatures.
Application: These nozzle bricks find extensive application in the furnace lining of medium and small capacity furnaces, such as glass furnaces, blast furnaces, hot-air furnaces, cement furnaces, chemical furnaces, and other heating-engineering equipment.
