Entre muitos materiais refratários,tijolos de sílicahave become the key material for industrial high-temperature furnaces due to their excellent refractory properties and chemical stability. Silica bricks are mainly composed of silicon dioxide (SiO2), and their purity is usually over 93%, or even as high as 95%. This high purity ensures that silica bricks have excellent refractoriness and chemical estabilidade .
Silica bricks have extremely high refractoriness, which can reach 1690℃to 1730℃. They can maintain a stable structure in extremely high temperature environments and show strong heat resistance. In addition, silica bricks have a low thermal expansion coefficient, which helps to reduce the thermal stress generated during high temperature changes, thereby improving the overall stability of the equipment. At the Ao mesmo tempo, os tijolos de sílica também têm boa resistência à erosão da escória ácida e têm forte resistência a substâncias corrosivas, como escória ácida e metal fundido, garantindo sua longa vida útil de serviço .
The manufacturing process of silica bricks is complex and delicate, mainly including the steps of raw material preparation, mixing and homogenization, molding, drying, firing, inspection and packaging. First, high-purity silica is selected as the raw material, crushed and screened to ensure the uniform particle size of the raw material. Then, the silica is mixed with a small amount of binder, and the uniformity of the raw material is improved by homogenization. Next, a hydraulic press or press is used to press the mixed raw materials into bricks of the desired shape. The bricks are dried in a drying chamber to remove moisture from them to prevent cracks during the firing process. Finally, the dried bricks are fired in a high-temperature kiln to form hard Os tijolos de sílica .} controle de temperatura durante o processo de disparo é crucial, e é necessário controle de temperatura preciso para garantir a qualidade dos tijolos de sílica . que os tijolos de sílica queimados precisam ser resfriados lentamente para reduzir as rachaduras causadas por estresse térmico. finalmente, as resfriados de silica embalado .
Silica bricks are widely used in the industrial field. They are important lining materials for key equipment such as steelmaking furnaces and electric furnaces, and play a vital role in ensuring the smooth progress of the steel production process. In the glass manufacturing process, silica bricks, as refractory materials for furnaces, provide a stable environment for the melting and clarification of glass liquid. In addition, silica bricks are also widely used in the chemical industry to manufacture acid-resistant equipment, such as production equipment for chemical products such as sulfuric acid and nitric acid. In thermal power plants, silica bricks, as refractory lining materials for boilers, withstand high temperature and high pressure environments, and contribute important forces to the generation of electric energy. Silica bricks are also used Para construir fornos de alta temperatura e fornos de túnel, e eles também desempenham um papel insubstituível em outros fornos industriais de alta temperatura, como fornos de disparo de cerâmica e fornos de cimento .
