Application
Semi silica brick is made of quartz sand and kaolin in special grain fineness. As it contains more quartz sand than other materials, its property is between clay brick and silica brick. It is mainly used as the coke oven bottom, liner and flue, etc.
They are widely used for hot blast furnace,coke oven,glass furnace.The products can be made according with the customers' requirement
