Характеристики

Product Introduction

The refractoriness of clay bricks is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks. Because the clay brick contains mullite crystals with high refractoriness, it also contains nearly half of the low melting point amorphous glass phase.

Product Presentation

Mainly used for pizza stove, oven, masonry blast furnace, hot blast stove, electric stove top, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina bricks are also widely used as open hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc.
