Aluminum-silicon carbide refractory ramming mass
Classification:
Product Details
The ramming mass for blast furnace infrastructure is made of silicon carbide, graphite, anthracite, coke and other materials. The phenolic resin, tar or asphalt is used as a binder. After stirring and mixing, it is made into an unshaped refractory material suitable for filling different parts of the blast furnace. It is constructed by ramming method.
Features:
1, Good thermal conductivity;
2. Resistance to slag and iron erosion;
3, Resistant to scouring.
Transportation and storage:
1. During the transportation and storage of the ramming materials, they must be noted that the sealed packaging bags should not be damaged to prevent the materials from hardening;
2. If the material inside the package is hard, it can no longer be used.
