Anhydrous Taphole Clay for blast furnace
The description of Anhydrous Taphole Clay
Anhydrous Taphole Clay is a key refractory material that is related to the smooth operation of the blast furnace during the training process of the blast furnace. Anhydrous Taphole Clay is mainly used to fill the iron hole. In the tapping operation in front of the Kochi furnace, the function of the Anhydrous Taphole Clay is like a valve. , Open the tap hole. After tapping, the tap hole can be blocked in time, and sufficient tap time must be ensured. The gun mud is required to have good workability (filling, openness), airability, sintering, the combination of new and old gun mud, corrosion resistance and resistance to brushing, etc., especially when spraying during the iron casting process Short, slow reaming speed
The composition of Anhydrous Taphole Clay
The composition of Anhydrous Taphole Clay can be divided into two parts-refractory aggregate and binder.
Refractory aggregate refers to refractory raw materials such as
corundum, mullite, coke gemstone, and modified materials such as
coke and mica. The binder is organic materials such as water or tar
pitch and phenolic resin, and is also mixed with SiC, Si3N4,
expansion agents and additives. The aggregate is composed of a
matrix according to a certain particle size and weight, and it has
a certain degree of plasticity under the adjustment of the binder,
so that the molten iron can be blocked by the mud cannon.
Classification of Anhydrous Taphole Clay-Classified by its binder
1.Water-based mud
2.Organic materials such as tar, resin, etc. are used as binders
called anhydrous gun mud.
3.Special cannon mud with special organic materials as binder, such
as: environmental protection cannon mud
If pure tar is used as the binder, the coking and hardening temperature is about 200°C; if it is a tar-asphalt composite binder, the coking and hardening temperature is about 360°C. Because the coking temperature of pitch is high, the coking value of pitch-added gun mud becomes higher. The amount of tar added also affects the softening point and coking value of the asphalt.
| Term | Environmentally Tap-hole | Waterless Tap-hole | Water Tap-hole |
| Binding Agent | Resin | Tar | Water |
| Al2O3(%) | ≥27.00 | ≥25.00 | ≥25.00 |
| SiC+C(%) | ≥30.00 | ≥30.00 | >25.00 |

| Bulk Density(g/cm3) | 1.60~2.20 | 1.60~2.20 | 1.40~1.80 |
| Cold Compressive Strength(MPa) | ≥8.0 | ≥10.0 | ≥6.0 |
| Apparent Porosity(%) | ≤35.0 | ≤32.0 | ≤40.0 |
Main functions of Anhydrous Taphole Clay
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 under high temperature, no molten iron leakage due to shrinkage.
