Preparation process of special magnesium oxide
The invention discloses a preparation technology of special magnesium oxide, and relates to the technical field of special magnesium oxide preparation, and the preparation technology comprises the following steps: crushing magnesite, processing the magnesite into a plurality of ore blocks, screening out the ore blocks with high magnesium content, further crushing, setting the initial rotating speed of a converter, starting the converter and preheating, pouring the ore blocks into the converter, continuously heating the converter, closing the converter and stopping heating when the temperature and heating time of the converter meet the requirements, cooling the converter to the environment temperature, completing the first firing of the magnesium oxide, resetting the rotating speed of the converter, starting the converter and heating, and closing the converter and stopping heating when the temperature and heating time of the converter meet the requirements; and the converter is cooled to the environment temperature, the special magnesium oxide obtained after repeated firing is taken out and mixed and bagged, and preparation of the special magnesium oxide is completed. A repeated calcination method is adopted, and the prepared magnesium oxide is relatively high in catalytic performance, so that the combustion performance of the double-base propellant is improved.
本发明公开了一种特种氧化镁的制备工艺，涉及特种氧化镁制备的技术领域，包括以下步骤：将菱镁矿进行粉碎，加工成数个矿石块，筛选出镁含量高的矿石块进一步粉碎，设置转炉的初始转速，开启转炉并进行预热，将矿石块倒入转炉中，继续对转炉进行升温，待转炉温度、升温时间达到要求时，关闭转炉并停止升温，待转炉冷却至环境温度后，完成氧化镁的第一遍烧制，重新设置转炉转速，开启转炉并加热，待转炉温度、升温时间达到要求时，关闭转炉并停止升温，转炉冷却至环境温度，将重复烧制后的特种氧化镁取出后进行混同装袋，完成特种氧化镁的制备。本发明采用重复煅烧法，制备的氧化镁催化性能较高，从而提升双基推进剂的燃烧性能。
