Ramming mass (induction furnace lining)
What it is
A dry granular refractory, usually silica-based, rammed and sintered in place to form the working lining of an induction furnace. It is consumed and replaced on a short cycle rather than lasting a campaign
It is the refractory product tied to secondary steelmaking rather than to blast furnaces or large EAFs
Impact on industries
- Demand tracks India's large and growing induction furnace base, which is a different and faster-growing customer set than integrated plants
- Short lining life means frequent repeat purchase, so it behaves as a consumable annuity rather than a project sale
- Highly fragmented and price-competitive, since a small secondary mill buys on cost rather than on lining-life analytics
- Quality directly determines lining life, so the technical case exists but the customer base is least equipped to evaluate it
