How to distinguish refractory refractoriness according to their raw material

Refractory material is essential for industrial furnace lining materials, in the progress of science and technology, furnace generation upgrading, resulting in the production process of refractory brick also has been greatly improved, and these promotion focus on refractoriness, refractoriness, slag resistance, spalling resistance, at the same time, types and applications refractory materials also have multiple orientation change, different refractory, different materials, refractory material refractoriness is generally determined by the material.

    1. clay brick: 1610 ~ 1750 degrees centigrade
    2. silica brick , 690 to 1730 degrees centigrade 
    3. crystalline silica: 1730 ~ 1770 degrees centigrade
    4. hard clay: 1750 ~ 1770 degrees centigrade
