BASIC INTRODUCTION

In induction furnaces working face of the main crucible is lined with a suitable ramming mass. 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.

Requirement Of A Proper Lining:

Thermal characteristics: it should withstand the stresses developed by the thermal cycle in operation.
It should be chemically insert to the metal being melted: chemical inertness to molten metal can be achieved by using acid lining for acid slag & basic lining for basic slag.
It should have enough structural strength to withstand operating conditions.
The thickness of refractory lining must be such as to ensure good electrical efficiency and thick enough to counter the risk of unexpected failure and major damage to the coil.
It should have high erosion resistance.
It should have low thermal & electrical conductivity.
It should have proper hardening characteristic.
It should have easy installation procedure.
It should be easily repairable, economical & posses ease of knocking/removal.

COMPARISON MANUAL LINING V/S LINING USING VIBRATOR

S.NO	MANUAL LINING	LINING USING LINING VIBRATOR
1	Erratic and shorter lining life	Consistent and enhanced lining life
2	Unpredictable production	Predictable and increased total output tonnage
3	Density of Lining is not uniform	Density of lining is uniform throughout the shell
4	Lining thickness is not uniform around the former	Lining thickness is absolutely uniform around the former
5	Refractory material in the tapered Section of the former is not completely deaerated leading to non-uniform erosion of lining and problems like elephant foot & leakage	Material in the tapered section of the former is completely dense achieving max. & uniform compaction. Thus erosion is uniform in the tapered section eliminating any possibility of elephant foot & leakage due to weak lining.
6	Refractory material in the tapered Section of the former is not completely deaerated leading to non-uniform erosion of lining and problems like elephant foot & leakage	Material in the tapered section of the former is completely dense achieving max. & uniform compaction. Thus erosion is uniform in the tapered section eliminating any possibility of elephant foot & leakage due to weak lining.
7	Labor Intensive	One skilled and one semi-skilled person can perform the whole lining
8	Lots of hazardous silica & dust in the air	Pollution free
9	Takes long hours to line the furnace from start to finish	Whole process of lining is completed in 3-4 hours
10	Hassles due to human component like attitude, error & fatigue.	Smooth and hassle free operation

BASIC LINING PROCEDURE

Bottom Lining

Pour the ramming mass in the bottom to the extent and level the ramming mass.
Start the ramming with bottom lining vibrator. Continue ramming till layer becomes hard. Keep on introducing layers of proper thickness and repeat the process till required level is attained.
Care has to be exercised not to allow antenna rod to bend during bottom lining installation.
