Microwave Drying of Monolithic Refractories

摘要

Monolithic refractory technology has been developed with the purpose of reducing the total refractory cost.The technology includes mixing,installing by casting,ageing,drying and high performance monolithic refractories.One of the most important things is drying shortly without explosion hazard.In concerning with this drying,they were developed the combination drying method using microwaves and hot air.Heating by microwave is internal heating,therefore,it is easier rapid heating until back of structure with appropriate microwave power applied.This paper reports on microwave absorbing and drying behavior of some kinds of monolithic refractories.
