Induction Silica Ramming Mass

Induction furnaces are latest furnaces used for melting of the metals specially the Iron. There furnaces requires the ramming mass for insulation or lining between coil and melting metals. Induction furnace Ramming Mass is produced from the Silicon dioxide stone. It is made of SiO2 (Silicon dioxide). Silica Ramming Mass (SiO2) is acidic in nature. Induction furnace Ramming Mass is used in powder form for lining or ramming in induction furnace. 

 

Good quality quartzite stone is used to produce the Silica ramming mass. Very high purity quartzite stone is used to produce the Induction furnace Ramming Mass. Quartzite stoner is broken crushed in machines, and then it is powdered. If there will be impurities in the mineral stone, then it may create problem in function of the induction furnace. Impurities in stone will produce more amount of the liquid at heavy temperature. 

An ideal granulometric composition of commercial acidic Induction furnace Ramming Mass is given below.

 

 

SIZE                       PERCENTAGE

 

4mm to 1mm                33% 

 

1mm to 0.20mm          30% 

 

0.20mm to0.06mm      17% 

 

0.06mm & below         20%

 

Proportion of the finest material is very important, as it takes part in the sintering reaction in furnance. If the fine particles are more than recommended percentage then it may lead to adverse effect of on performance of ramming layer. 

 

Special attention should be paid towards the proportion of fine size; it should be within defined range. There is adverse effect on the service behavior of lining if fine particles present in more quantity than required. Since the finest particles mainly takes part in the sintering reaction.
