Preparation method and device of unfired magnesite brick
The invention relates to the technical field of magnesite brick preparation, in particular to an unfired magnesite brick preparation method which comprises the following steps: S1, taking magnesite as a main raw material, adding an additive and a binding agent, and mixing; s2, preparing magnesite bricks by using a preparation device; and S3, drying the magnesite brick formed in the step S2 for 8-12 hours at the temperature of 200 DEG C. Compared with the existing production technology, the preparation method disclosed by the invention has the advantages that the time is greatly saved, and experiments show that all indexes of the finished product are superior to those of the unfired magnesite brick produced by the existing technology. The normal-temperature compressive strength reaches 90 MPa or above, and the porosity can be effectively controlled to be about 10%. And various chemical analysis indexes meet or even are superior to the requirements of the burnt magnesia brick.
本发明涉及镁砖制备技术领域，尤其是一种不烧镁砖的制备方法，包括下列步骤：S1：以镁砂为主原料，加入添加剂及结合剂进行混炼；S2：使用制备装置制成镁砖；S3：将S2成型的镁砖在温度为200℃的条件下，烘干8‑12小时，相比于现有的生产技术而言本发明大幅度节省时间，且经实验表明，本发明的制成品各项指标均优于现有工艺所生产的不烧镁砖。常温耐压强度均达到90兆帕以上，气孔率可有效控制在10％左右。各项化学分析指标均符合甚至优于烧镁砖的要求。
