Silica ramming mass is an acidic monolithic refractory made of high-purity quartz and professional additives. Featuring outstanding high-temperature stability and easy construction, it's widely used in metallurgy, foundry and glass industries, and is the ideal lining material for induction melting furnaces.
I. Core Performance Features
1. Excellent high-temperature resistance: It offers a refractoriness above 1580℃ and a long-term service temperature of 1500–1700℃, resisting softening and deformation under high-temperature melting conditions.
2. Stable volume performance: With a controlled thermal expansion rate, it barely deforms during temperature cycles, effectively preventing lining cracking and material leakage and ensuring furnace tightness.
3. Strong erosion and scour resistance: After ramming, the material forms a dense seamless structure that withstands acidic slag and molten metal erosion, greatly extending furnace lining service life.
4. Good thermal shock resistance: It adapts well to frequent furnace startup and shutdown and sharp temperature changes, avoiding structural damage.
5. Simple and cost-effective construction: The dry-type formula requires no complex debugging. It can be compacted quickly by hand or machine with good overall integrity, lowering construction and maintenance costs.
II. Main Applications
This product is mainly used for medium-frequency and power-frequency induction furnaces for melting cast iron, cast steel and non-ferrous metals. It also suits low-temperature sections and flue linings of glass kilns, as well as repairing and casting vulnerable parts such as kiln bottoms, walls and slag outlets under acidic high-temperature conditions.
III. Product Advantages
Compared with alumina and magnesia refractories, silica ramming mass is more suitable for acidic melting environments with lower maintenance costs and higher cost performance. Its dense lining structure stabilizes furnace operation, reduces energy consumption and minimizes shutdown frequency, making it a cost-effective refractory choice for metallurgy and foundry industries.
