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

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.

Inject the slurry

In-furnace repair mortar is an unshaped refractory material used for lining repairs in thermal equipment such as blast furnaces. It is applied by injecting the slurry into cracks or damaged areas using a mud pump, effectively filling, sealing, and restoring the affected zones. This material is characterized by its excellent fluidity, allowing it to penetrate even tiny fissures, while also exhibiting strong adhesion to substrates like refractory bricks and castables. Additionally, it boasts superior resistance to high temperatures and corrosion. Commonly employed for repairing equipment such as blast furnaces, hot-blast stoves, and rotary kilns, this mortar helps extend equipment lifespan and significantly reduces downtime for furnace maintenance and inspections.

Mud-Set Ramming Material

By compacting and ramming, a strong, dense mud-casing structure is formed, serving the same purpose as mud-casting material.

Refractory Plastic

Plastic refractories, often referred to as plastic refractory materials, are amorphous refractory materials crafted from a blend of refractory raw materials mixed with appropriate binders and plasticizers. After being kneaded and stored, these materials exhibit exceptional plasticity, making them highly versatile for shaping through methods like tamping or extrusion. They are commonly used in lining or repairing high-temperature kilns and heating equipment, prized for their excellent plasticity, thermal shock resistance, and corrosion durability. With a wide variety of material compositions and binder types available, plastic refractories can be tailored to suit specific application needs—making them indispensable for high-temperature equipment across industries such as steel production and cement & building materials manufacturing.

Coke Oven Spray Coating

Coke oven spray coating is an unshaped refractory material used for repairing coke oven structures (such as furnace walls, furnace roofs, and regenerative chambers). Applied via a spraying process, it forms a protective layer over damaged areas, effectively addressing high-temperature gas erosion, mechanical wear, and thermal shock damage. This coating boasts excellent adhesion, superior thermal shock resistance, and strong anti-slagging performance. It’s ideal for repairing worn-out coke oven walls, protecting the surfaces of regenerative chamber checker bricks, and providing insulating coatings on furnace roof sealing walls—ultimately extending the service life of the coke oven while minimizing heat loss and preventing gas leakage.
