Background

The material which is allowed to be used in a high-temperature environment by physical and chemical properties is called a refractory material, the acidic refractory material takes silicon oxide as a main component, commonly used silica bricks and clay bricks are adopted, the neutral refractory material takes aluminum oxide, chromium oxide or carbon as a main component, the alkaline refractory material takes magnesium oxide and calcium oxide as main components, commonly used magnesia bricks are adopted, and after the refractory material is produced and formed, the refractory material needs to be fully dried, so that the use strength of the refractory material can be well ensured, and the performance damage or reduction caused by the water-containing or damp state of the refractory material can be avoided.

Most of the existing refractory material drying devices adopt an electric heating drying mode, and the electric heating drying mode is low in drying efficiency due to lack of air flow, long in time, inconvenient in carrying and using of refractory materials and large in occupied area of equipment.

Microwave drying is a novel drying mode. During drying, microwave energy directly acts on medium molecules to be converted into heat energy, and because the microwave has penetrability, the medium can be heated inside and outside simultaneously without heat conduction, so that the heating speed is very high, and the drying speed can be shortened by multiple times. Meanwhile, regardless of the thickness of the object to be dried, because the medium of the object is heated inside and outside simultaneously, the temperature difference between the inside and the outside of the material is small, the heating is uniform, the condition of non-uniformity in electric drying can not be generated, the drying quality is greatly improved, and the drying time is shortened. Microwave drying is comparatively common in food, medicinal material processing, nevertheless because refractory material's thickness, length differ, consequently need design a continuous drying device who is applicable to different specification refractory materials, makes it can refractory material fast drying to satisfy continuous production, improve production efficiency's purpose.
