The acidic silica ramming mass plays an optimal role in this process. Silica ramming mass is basically a proportionate mixture of QuartzQuartzite graded and blended to homogeneity. The pure stones cleaned and handpicked are crushed in a closed circuit of machines then passed through high gauss magnets to remove free iron induced due to grinding media and then are mixed with utmost care to ascertain appropriate mix to suit furnace requirements. Silica ramming mass as used by the consumer are of numerous types depending on the basic requirements of the consumer. They vary with factors like, size of furnace, make of furnace, charge mix being used, tapping temperature, coil condition, machine sensitivity, working atmosphere (i.e. dry, damp, humid etc.) and economies. The silica ramming mass is a generated mixture of quartzquartzite mixed in proportion to form a monolith body. It is rammed in furnace using manual ramming or electrical rammer for optimal performance. If the product is PRE-MIX (i.e. Boric acid added by the manufacturer) then it is directly rammed or if non-premix is used then it has to be added at the consumer end as per requirement. The proportion of same varies from 0.8 % for slag zones to 1.4% in tapers and bottoms.
