The function and advantages of anhydrous gun mud

The main function:

1) To block the tap hole, the gun mud is required to have good filling and sintering properties;

2) Stable tapping, requires gun mud to be easy to open the taphole and resistant to erosion and erosion;

3) To protect the hearth, it is required that the gun mud has no cracks when it is heated quickly, and the bonding strength of the new and old gun mud is high;

4) The opening performance is good, the opening machine bit is easy to drill;

5) Moderate plasticity, which is convenient for mud gun operation and formation of iron mouth mud bag;

6) Good volume stability, small volume change at high temperature, no molten iron leakage due to shrinkage.

Advantage:

1) High strength, and maintaining the stability of the blast furnace conditions (steel hole depth, tapping time fluctuations, full air blocking rate, etc.) is of great significance, so that the blast furnace has a basis for increasing production.

2) Strong slag resistance. The unit consumption of cannon mud is low, generally one-fifth of water cannon mud.

3) It has certain expansion properties. With proper porosity and strength, it can adapt to more than 2000m. Used in large blast furnaces.
