Aluminum-silicon carbide refractory ramming mass

The ramming mass for blast furnace infrastructure is made of silicon carbide, graphite, anthracite, coke and other materials.
Classification
没有此类产品
DESCRIPTION

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.
