            新型建材之“堿性耐火材料”(氧化鎂、輕燒鎂粉等) "Alkaline refractories" for new building materials (magnesium oxide, lightly burned magnesium powder, etc.)

            http://www.usygg.com堿性耐火材料主要是指以輕燒鎂球、輕燒鎂粉為主要成分的耐火材料,對堿性渣有較強的抗侵蝕能力。 

            常用的是鎂球。含氧化鎂80%~85%以上的鎂球,對堿性渣和鐵渣有很好的抵抗性,耐火度比粘土磚和硅磚高。主要用于平爐、吹氧轉爐、電爐、有色金屬冶煉設備以及一些高溫設備上。

            堿性耐火材料特點

            耐火度高于1580℃的無機非金屬材料。耐火度指耐火材料錐形體試樣在沒有荷重情況下,抵抗高溫作用而不軟化熔倒的攝氏溫度。耐火材料與高溫技術相伴出現,大致起源于青銅器時代中期。中國東漢時期已用粘土質耐火材料做燒瓷器的窯材和匣缽。20世紀初,耐火材料向高純、高致密和超高溫制品方向發展,同時出現了完全不需燒成、能耗小的不定形耐火材料和耐火纖維?,F代,隨著原子能技術、空間技術、新能源技術的發展,具有耐高溫、抗腐蝕、抗熱振、耐沖刷等綜合優良性能的耐火材料得到了應用。

             

            http://www.usygg.com Alkaline refractory mainly refers to refractory with light-burned magnesium balls and light-burned magnesium powder as the main components, and has strong resistance to erosion by alkaline slag.

            Commonly used are magnesium balls. Magnesium balls containing 80% to 85% of magnesium oxide have good resistance to alkaline slag and iron slag, and their fire resistance is higher than that of clay bricks and silica bricks. It is mainly used in open hearth furnace, oxygen blowing converter, electric furnace, non-ferrous metal smelting equipment and some high temperature equipment.

            Characteristics of alkaline refractories

            Inorganic non-metallic materials with a fire resistance higher than 1580 ° C. Refractory refers to the Celsius temperature of the refractory cone sample without resistance to high temperature without softening and melting. Refractory materials and high-temperature technology have emerged, which originated roughly in the middle of the Bronze Age. During the Eastern Han Dynasty in China, clay-based refractory materials were used to make porcelain kiln materials and casks. At the beginning of the 20th century, refractories developed towards high-purity, high-density, and ultra-high-temperature products. At the same time, unshaped refractories and refractory fibers that did not require firing at all and had low energy consumption appeared. In modern times, with the development of atomic energy technology, space technology and new energy technology, refractory materials with comprehensive and excellent properties such as high temperature resistance, corrosion resistance, thermal vibration resistance, erosion resistance, etc. have been applied.
