Dry material is an unshaped refractory composed primarily of magnesia-based refractory aggregates and fine powders, formed by vibration. Under vibration, the material forms a dense and uniform structure, and upon heating, develops strength through thermosetting binders or ceramic sintering agents. This product is used as lining material in containers such as ladles and tundishes, and as liners or packing materials in high-temperature equipment like converters. Furthermore, it is widely applied in high-temperature processing equipment in industries such as power generation and chemical processing, effectively addressing issues of corrosion and wear in high-temperature and high-pressure equipment.
