lining is the imported part of induction furnace, furnace performance is directly related to the lining performance. Well-stabilized lining results in smooth working of furnace, optimum output and better metallurgical control. The lining practice best suited to particular foundry will depend upon the furnace capacity and design, metal being melted and output etc.
for successful and consistent lining practice monitoring the following parameters is essential.
use of proper grade of lining material.careful and systematic lining practice.consistency in working conditions.
types of ramming mass :
acidic/silica ramming massbasic ramming massneutral ramming mass
silica/acidic ramming mass :
the silica (sio2), used as lining, is acidic in nature. It is used in powdered condition. It is produced by crushing and grading of good quality quartz and quartzite having very high purity. The impurities present will produce unpredictable and more amount of liquid phase at high temperature thereby lowering chemical and mechanical resistance of lining. High purity silica yields more lining life. It is also results in considerable uniformity in physical properties.
the compact lining results in greater strength and life. The compactness (packing density) depends upon granulometric composition of ramming mass. It should be such that it forms the least open space between particles.
Size | Percentage |
---|---|
-4mm to 1mm | 33% |
-1mm to 0.20mm | 30% |
0.20mm to 0.06mm | 17% |
0.06mm & below | 20% |
Particular attention should be paid towards the proportion of fines within a certain tolerance. It has adverse influence on the service behavior of lining if present in more amounts than required. Since the finest particles mainly take part in the sintering reaction.
