Production method of 80 sintered magnesite brick
The invention discloses a production method of an 80 sintered magnesite brick. The 80 sintered magnesite brick is prepared from the following components in parts by weight: main raw materials for preparing the 80 sintered magnesite brick: high-silicon magnesia, 90 magnesia, silica fume and a binding agent; the production method comprises the following steps: step a, selecting materials according to specified parts, and mixing the high-silicon magnesia as the aggregate for 10-15 minutes by using a QHX-250 planetary forced mixer to obtain the uniformly mixed magnesite brick aggregate; and b, mixing the uniformly mixed aggregate and binding agent for 5-10 minutes by using a QHX-250 type planetary forced mixer. According to the 80 sintered magnesite brick production method provided by the invention, high-silicon magnesite which is prepared from high-silicon magnesite and reverse flotation magnesite tailings and contains more than 80% of MgO is used as a main raw material, so that the utilization rate of magnesite resources is improved while high-grade magnesium resources are saved, the sintering temperature of a product is reduced, the production energy consumption is reduced, and the production cost is reduced. And a pollution-free MgCl solution is used as a binding agent, so that environmental protection and emission reduction are facilitated.
本发明公开了一种80烧成镁砖生产方法，原料配方按重量份数由如下组分：制备80烧成镁砖主要原料：高硅镁砂、90镁砂、硅灰和结合剂；其生产方法包括如下步骤：步骤a：按照指定份数选取材料，先将作为骨料的高硅镁砂使用QHX‑250型号的行星式强制混合机混合10min‑15min，获得混合均匀的镁砖骨料；步骤b：将混合均匀的骨料和结合剂使用QHX‑250型号的行星式强制混合机混合5min‑10min。本发明提供一种80烧成镁砖生产方法，利用高硅菱镁矿和反浮选菱镁矿尾矿制备的MgO含量在80%以上的高硅镁砂为主要原料节约高品位镁资源的同时提高了菱镁矿资源利用率，降低了制品的烧成温度，节约了生产能耗，使用无污染的MgCl溶液作为结合剂，有助于环保减排。
