Comparison of Life Cycle for Various Refractory Materials of Induction Melting Furnace Wall under Thermal Fatigue Loading Conditions

Abstract

Furnaces are most important as it is constantly used for melting of materials. Induction furnaces are
more worthwhile as no fuel is required. It is a main issue to go looking out life cycle of Induction Melting Furnace
Wall under load variant. The induction melting furnace wall is made-up of Silica Ramming Mass, Alumina
Ramming Mass, Magnesia Ramming Mass and Zirconia which are forms of refractory materials. The failure occurs
considering that of cyclic thermal stresses as a result of heating and cooling cycles. Temperature distribution and
thermal stress distribution fields of the induction melting furnace refractory wall had been calculated by way of
utilising explicit finite change evaluation centred on the bodily description of its failure under low cycle thermal
fatigue stipulations. The life span of the refractory wall is required to be found out by the use of primary thermal
stresses created inside the refractory wall of induction melting furnace wall from modified S – log N Curves.
