Silica ramming mass is scientifically formulated using high-quality quartz sand and silica as aggregates with composite binders. As a dry refractory material, it features excellent high-temperature stability, acid corrosion resistance and good compact forming property. It's the core material for lining construction, maintenance and repair of acid high-temperature furnaces including induction furnaces, glass furnaces, coke ovens and hot blast stoves.
I. Core Performance Advantages
1. Excellent high-temperature volume stability
This material undergoes stable phase transformation at high temperatures. It exhibits uniform thermal expansion at 1000℃ ~ 1450℃ and resists shrinkage and cracking. The formed lining has high integrity with no risk of spalling or gaps, supporting long-term continuous stable operation of furnaces under high temperature.
2. Superior acid corrosion resistance
Acidic in nature, the material withstands corrosion by acidic flue gas, molten slag and silicate media. It effectively resists erosion from molten glass and acidic fumes, greatly lowering the chance of lining damage and spalling, and suits working conditions of various acid high-temperature furnaces.
3. High density and reliable structural tightness
After mechanical compaction during dry ramming construction, the material is densely packed with low porosity to form a uniform compact lining. Unlike brick structures, it eliminates heat and air leakage through brick joints, improves furnace air tightness and reduces heat consumption during production.
4. Strong construction adaptability and good workability
Supplied as dry material requiring no water mixing, it allows simple and flexible construction. It can be shaped for complex structures such as furnace bottoms, corners and irregular furnace walls, delivering high construction efficiency and forming smooth and dense linings.
II. Product Application Value
Boasting stable performance, good corrosion resistance and convenient construction, this material effectively extends the service life of furnace linings, shortens construction periods and cuts operation and maintenance costs. It's the preferred refractory material for energy saving and efficiency improvement of acid high-temperature furnaces.
