Basic Ramming
Monilothics
Magnesite Ramming Mass
Suitable for ramming of Electric Arc Furnaces of various capacities and also as a repair material with quick thermosetting properties. This is also suitable for Ultra High Power (UHP), EBT (Eccentric Bottom Tapping). Furnaces.
Basic Ramming Mass
Suitable for Induction Furnaces for production of high quality alloy steel, mild and low alloy steel.
Basic Gunning Mass
Suitable for gunning of LD converters and Electric Arc Furnaces for production of high quality alloy steel, mild and low alloy steel.
Tundish spraying / Gunning Mass
Tundish is no longer an intermediate between the Ladle and Mould; it plays a vital role in the quality of continuous cast steel as it is the final container prior to the steel entering the Mould. The working lining of Tundish plays an important role in providing quality and cost effective steel. Earlier, the Tundish used to be lined with bricks/MgO Boards. This is being changed to MgO based sprayed/gunned lining. This practice has the distinct advantage of:
1. Quicker turnaround.
2. Higher life.
3. Easy deskulling / lesser debris generation.
4. Saving in labour.
5. Better Quality of steel.
