A Two-Dimensional Finite Element Model for Kiln-Drying of Refractory Concrete

ABSTRACT

A two-dimensional finite element model is developed for kiln-drying of refractory concrete. Using this model simulations are carried out for refractory concrete castings of different thicknesses to investigate the effects of drying schedules on pore steam pressure and moisture removal. Simulation results from both one- and two-dimensional models are compared and discussed. On the basis of the simulation results new realistic drying schedules are suggested.
