Ramming Mass
Ramming mass is an unshaped refractory material with rational particle size distribution, containing no or only trace moisture. It is compacted by manual or mechanical ramming and can be put into use quickly without complex curing. It is mainly used for constructing working linings, bottom linings and repair layers of high-temperature furnaces, suitable for harsh working conditions with strong scouring, corrosion and rapid temperature changes.
Product Classification
1. By Material: High alumina ramming mass, magnesia ramming mass, magnesia-chrome ramming mass, silicon carbide ramming mass, acidic/basic ramming mass
2. By Application: Furnace bottom ramming mass, furnace slope ramming mass, induction furnace ramming mass, electric arc furnace ramming mass, special repair ramming mass
3. By Bonding System: Inorganic bonded, resin bonded, ceramic bonded ramming mass
Core Advantages:
1. Easy & Efficient Construction: No water mixing required; direct on-site ramming for compaction. It gains strength immediately after forming, enabling fast furnace baking and commissioning, greatly shortening construction period.
2. Excellent High-Temperature Corrosion Resistance: Made of high-purity refractory aggregates and bonding systems, resistant to molten metal, slag, acid and alkali corrosion, ideal for metallurgy, chemical and other severe corrosion scenarios.
3. Thermal Shock & Erosion Resistance: High density and stable structure, withstand frequent temperature fluctuations and material scouring without peeling or cracking, extending furnace lining service life.
4. Wide Adaptability: Formulas can be customized according to operating temperature and corrosion type, covering medium, high and ultra-high temperature scenarios for both repair and integral masonry.
5. Outstanding Repair Performance: Specially used for rapid repair of local furnace damage, firmly bonded with original lining, reducing downtime for maintenance.

Main Applications:
1. Metallurgy: Medium/high frequency induction furnaces, electric arc furnaces, steel furnace bottoms, furnace slopes, tapping spouts
2. Non-ferrous Metals: Smelting furnace linings for copper, aluminum, zinc and other non-ferrous metals
3. Chemical & Building Materials: Glass furnace bottoms, cement kiln linings, chemical high-temperature reactor linings
4. Others: Local repair of various industrial furnaces, integral masonry of high-temperature furnace bottoms
Carbon Ramming Mass Application:
According to different blast furnace types and different material design requirements, carbon ramming mass are mainly used in the gaps between the blast furnace bottom carbon bricks and the bottom sealing plate and between the hearth carbon bricks and the cooling staves, as well as the bottom water-cooling pipes. For leveling above the center line and filling of the cooling stave, all parts require that the carbon ramming material after ramming has a certain strength and density, filling every corner and small gap, so as to prevent leakage of molten iron and gas. requirements, and the thermal conductivity of the carbon ramming material must be basically consistent with the performance of the hot carbon bricks and cooling staves of the blast furnace, so as not to affect the life of the blast furnace and maintain normal production of the blast furnace.
