Many people don’t realize that maintenance is interrelated for induction-furnace linings and coils: Short lining life and coil life result in increased downtime, costs, and frequent coil changes. To understand this correlation better, let’s focus on a coreless furnace melting ferrous materials, with silica refractory as the working lining. The observations would be similar with nonferrous materials and an alumina-based refractory.
Maximizing Lining Life and Coil Life
In a coreless induction melting furnace, promoting longer lining life can also improve coil life, resulting in less downtime, lower production cost-per-ton, and reduced maintenance costs.
