Structure shangzhuang Refractories Co., Ltd., Zhengzhou City, with your understanding of how acidic refractories refractory silicon oxide as the main component, commonly used with brick and clay. Silica brick is more than 94% silica-containing siliceous products, raw materials used are silica, silica brick scrap, etc., its acid resistance to slag penetration ability, high softening temperature under load, the volume does not shrink after repeated firing, and even a slight expansion; But its vulnerability to erosion of basic slag furnace steelmaking casting refractories, thermal shock resistance is poor. Mainly used silica brick oven, glass melting furnaces, furnaces and other acidic thermal equipment. Refractory brick with clay as the main raw material, containing 30% to 46% alumina, is a weak acid refractories, thermal shock resistance, corrosion resistance to acid slag has wide application. Refractories Co., Ltd., Zhengzhou City shangzhuang discovery of new energy-saving effect of energy-saving compared with traditional refractory refractory, at least 20% -30% energy saving steel casting furnace refractories, refractory despite this new one of the sales price is higher than some of the conventional refractory material, but its low maintenance costs. According to statistics, the use of this energy-saving, environmental protection, and efficient steel casting furnace refractories refractories, only about ± 5% of its furnace temperature, and the temperature difference between the traditional refractory reach ± ??10% -30%, the cost of maintaining its Only about half of the traditional use of refractories. [Steel casting furnace refractories], steel casting furnace refractories, Refractories shangzhuang provided by shangzhuang Refractories.
