Monolithic Crown And Its Benefits, Colloidal Silica Bonded Refractories Technology

Magneco Metrel Inc is a world leader in monolithic, no cement, colloidal silica bonded refractory technology. This refractory technology has been utilised for crown construction with many crowns in service and operation including melter, regenerator, oxy-fuel melter and flu gas covers globally. This paper provides a short review of the history of the monolithic crown and its construction. The presentation will also focus on fundamental differences between monolithic crown and conventional brick/block crowns with regards to installation, maintenance, gas and alkali attack, energy saving, overall performance and cost benefits.
