| With the patented furnace advanced slag-free tapping system, charging, tapping and taphole refilling are possible under power-on conditions. |
|
| Gunning can be used to cover bare shell areas, repair a bottom hole, dress the spout or pipe a taphole. |
|
| Once the pig iron and slag has been tapped, the taphole is again plugged with refractory clay. |
|
| The crawler is launched through a 4-inch taphole drilled into the main using standard no-blow hot tap technology. |
|
| The Company will start shipping castables and refractory materials for the taphole in furnaces from March through the end of this year. |
|
| The software is sensitive to both positive and negative factors affecting cupola operation as it moves from the charge door to the taphole. |
|
| Prior to leaving the cupola a final time, the worker rams a small bott of moist molding sand over the inside of the taphole. |
|
| At the first sight of fluid entering the safety tuyere, the blast should be turned to relief and the taphole should be opened. |
|
| The investment the largest since the Indian owners took over the works in 2007 will see an enhanced fume extraction system and modern taphole equipment installed. |
|
| When the molten aluminum reaches a certain volume, it flows continuously out of the taphole into a connected holding crucible, where it is stored. |
