Laddle Mass |
|
| |
|
| Ladram |
|
| This is a Dunite based Ramming Mass. Dunite is a natural Mineral consisting of Forsterite as high as 90 % and above which makes the mineral a good refractory material. It is having high specific gravity and is resistant to slag. Due to good bulk density and higher thermal conductivity comparatively less time is required for preheating thus saving precious fuel / time. Ladles / Hand shanks made with Ladram gives much more life then silica lining. |

|
| |
| Method to Use: |
| Good compact ramming is required to be done by mixing 4-5 % diluted [ 1:1 ] Foundry Grade Sodium Silicate. Special attention to be taken at the impact area at the bottom. |

| Laddle Mix |
|
| This is a forsterite based water binding Ramming Mass. It is having a high specific gravity and resistant to slag. Due to good bulk density & higher thermal conductivity comparatively less time is required for pre- heating thus saving precious fuel & time. |
| |
| Method to Use: |
| Good compact ramming is required to be done by mixing 3-4 % water.. |
| |
| Preheating: |
| Slow preheating is required for first 3-5 hrs (depending in the capacity of the ladle).Thereafter ladle is to be kept in red hot condition at least for 1 hr. |
