USEFUL FOR MELTING :

Cast iron/Malleable/S.G.Iron/Mild Steel/Low Alloy Steels/Brass, Copper, etc.

METHOD OF INSTALLATION :

For Only Type Sil-Ram Dry Silica Ramming Masses.

The Ramming Mass is to be pre-heated in a clean tray to a temperature of about 80C to 90C   for removal of any moisture present.

It is important to ensure that the Ramming Mass is not contaminated with impurities during this reheating operating.

After cooling below 40C the Ramming Mass is to be mixed uniformly with Boric Acid Binder.

The percentage of Boric Acid will vary between 0.8% to 2.0% depending upon the operating temperature.  For cast  iron melting furnaces Boric Acid percentage is 1.4 to 1.5 and for steel melting furnace it is 1-1.2%.
