Main Trench Non-Baked Ramming Material
The main-channel unbaked ramming material is an unshaped refractory designed for blast furnace tapholes. It can be used directly without the need for baking, making it ideal for constructing, repairing, and maintaining blast furnace tapholes. This material enables rapid restoration of the taphole’s operational functionality, significantly reducing downtime during blast furnace shutdowns.
Baking-Free Ramming Material for Tuyeres
The non-baking ramming material for the runner section of a blast furnace is an unshaped refractory material designed specifically for use in the runner area. It has the unique feature of being ready-to-use without the need for baking. Primarily used for lining and repairing the runner sections of medium- and small-sized blast furnaces, it can also be applied to rebuild worn-out runners.
Slag Channel Non-Baking Ramming Material
Slag trough non-baked ramming material is an unshaped refractory used specifically for the slag trough area of blast furnaces. This material exhibits excellent high-temperature mechanical properties, effectively resisting erosion and scouring from molten slag, while also demonstrating superior thermal shock resistance and minimal post-calcination volume change. During construction, after thoroughly cleaning the slag trough, the material can be directly placed into the trough and firmly compacted by ramming—eliminating the need for pre-baking before use.
Carbon ramming mass is an amorphous refractory material primarily composed of carbon-based materials, applied through manual or mechanical tamping to create a dense, compact structure. It is widely used in high-temperature, slag-resistant, and electrically conductive applications—such as in submerged arc furnaces, electrolytic cells, and blast furnace hearths. Its key advantages include excellent resistance to molten-metal erosion, superior thermal conductivity, and the ability to accommodate complex furnace geometries during construction. The performance of carbon ramming mass hinges critically on the purity of the carbon raw materials and the sintering quality of the binding agents; proper selection can significantly enhance the erosion resistance and extend the service life of high-temperature equipment.
Baking-Free Ramming Material for Ferroalloy Furnaces
Iron alloy furnace non-baked ramming material is an unshaped refractory designed for lining construction or repair in iron alloy furnaces. Its key feature is that it can be used directly without the need for baking, simplifying the construction process and significantly reducing the lining installation timeline. Commonly applied to areas such as furnace bottoms and walls—both during new construction and repairs—it’s especially well-suited for smelting environments where high construction efficiency is critical.
Charging Machine Tamping Material
The ramming material for iron casting machines is an unshaped refractory material used in areas where molten iron is received and cast into shape. It is applied via a tamping process, requiring excellent resistance to high-temperature molten iron erosion, outstanding wear resistance, and superior thermal shock resistance. By optimizing the hardness of its aggregate and enhancing the performance of the binder, this ramming material not only ensures efficient iron casting but also helps extend equipment lifespan while reducing maintenance costs.
By compacting and ramming, a strong, dense mud-casing structure is formed, serving the same purpose as mud-casting material.
