| When the molten aluminum reaches a certain volume, it flows continuously out of the taphole into a connected holding crucible, where it is stored. |
| Once the pig iron and slag has been tapped, the taphole is again plugged with refractory clay. |
| Gunning can be used to cover bare shell areas, repair a bottom hole, dress the spout or pipe a taphole. |
| At the first sight of fluid entering the safety tuyere, the blast should be turned to relief and the taphole should be opened. |
| With the patented furnace advanced slag-free tapping system, charging, tapping and taphole refilling are possible under power-on conditions. |
| The Company will start shipping castables and refractory materials for the taphole in furnaces from March through the end of this year. |
