  輕燒鎂球" style="text-align: center; font-size: 16px;">http://www.pasaranuang.com耐火材料(輕燒鎂球、輕燒鎂粉等)是一類耐火度不低於1580℃的無機非金屬材料。廣泛應用於鋼鐵、有色金屬、玻璃、水泥、陶瓷、石化、機械、鍋爐、輕工、電力、軍工等國民經濟的各個領域,是保證上述產業生產運行和技術發展必不可少的基本材料,在高溫工業生產發展中起著不可替代的重要作用。

  自2001年以來,在鋼鐵、有色、石化、建材等高溫工業高速發展的強力拉動下,我國耐火材料行業保持著良好的增長態勢,已成為世界耐火材料的生產和出口大國。2011年中國耐火材料產量約占全球的65%,產銷量穩居世界耐火材料第一。

  據統計,2001-2010年耐火原料及製品產量穩步增長,其中“十五"末約為2001年的2倍;2010年全國耐火製品產量達2808.06萬噸,約為“十五"末的3倍。截止2011年,我國耐火材料行業共有規模以上企業1917家,從業人員超過30多萬人,實現銷售收入3376.79億元,實現產品銷售利潤477.37億元。

  對耐火材料(輕燒鎂球、輕燒鎂粉等)的性能,粒度的選擇極為重要。粒度的正確選擇直接影響耐火材料的質量,微粉及超微粉技術的引入,大大提高耐火材料製品的致密度,促進樣品的燒成,提高製品強度,改善耐火材料的耐用性和抗衝刷性。對於不定性耐火材料,尤其對於低水泥、超低水泥澆注料和自流澆注料,超微粉起著一定的結合劑作用,並且有減水效果。微粉的粒度及分布對試樣的加水量和流動性以及材料的性能影響也很大。


Refractory materials (light-burned magnesium balls, light-burned magnesium powder, etc.) are a class of inorganic non-metallic materials with a fire resistance of not less than 1580 ° C. It is widely used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electricity, and military industries. It is an essential basic material to ensure the production and operation of these industries and technological development. It plays an irreplaceable role in the development of high-temperature industrial production.


2001Since 2001, driven by the rapid development of high-temperature industries such as iron and steel, nonferrous metals, petrochemicals, and building materials, China's refractory industry has maintained a good growth momentum and has become a major producer and exporter of refractory materials in the world. In 2011, China's refractory output accounted for about 65% of the world's total, and its production and sales ranked first in the world.


According to statistics, the output of refractory raw materials and products increased steadily from 2001 to 2010, of which the end of the "Tenth Five-Year Plan" period was about twice that of 2001; the output of national refractory products reached 28.008 million tons in 2010, about three times that of the "Tenth Five-Year Plan period". . As of 2011, China's refractory industry has a total of 1,917 companies above designated size, employing more than 300,000 people, achieving sales revenue of 337.679 billion yuan, and product sales profits of 47.737 billion yuan.


For the performance of refractory materials (light burned magnesium balls, light burned magnesium powder, etc.), the choice of particle size is extremely important. The correct choice of particle size directly affects the quality of refractory materials. The introduction of micropowder and ultrafine powder technology greatly improves the density of refractory products, promotes the firing of samples, increases the strength of products, and improves the durability and erosion resistance of refractory materials. For uncertain refractories, especially for low-cement, ultra-low-cement castables, and self-flowing castables, ultrafine powders play a certain binding role and have a water-reducing effect. The particle size and distribution of fine powder also have a great impact on the amount of water and fluidity of the sample and the performance of the material.
