Preparation method of rare earth oxide fly ash ceramsite with high refractoriness under load
The invention provides a preparation method of rare earth oxide fly ash ceramsite with high refractoriness under load. The preparation method comprises the following steps: step 1, pretreatment of fly ash: carrying out oscillation, high-temperature roasting, grinding and sieving on the fly ash to obtain the ceramsite; step 2, preparation of ceramsite: carrying out ball milling and spray drying on rare earth oxide, and blending with the fly ash powder to obtain mixed powder; and step 3, a balling process: putting the mixed powder into a granulator, uniformly dropwise adding a binder into the mixed powder, and then aging and roasting the prepared ceramsite to obtain the rare earth oxide fly ash ceramsite. According to the preparation method of the rare earth oxide fly ash ceramsite with the high refractoriness under load, the fly ash ceramsite prepared by adding the rare earth oxide has the higher refractoriness under load, and the refractoriness under load is increased by 10% or above compared with ceramsite without adding the rare earth oxide.
本发明提供了一种高荷重软化温度的稀土氧化物粉煤灰陶粒的制备方法，包括如下步骤：步骤1是粉煤灰的前处理：将粉煤灰进行震荡、高温焙烧、研磨、过筛后得到；步骤2是陶粒的制备：将稀土氧化物进行球磨、喷雾干燥后与所述的粉煤灰粉体进行共混后得到混合粉体；步骤3是成球工艺：将所述的混合粉体置于造粒机中，将粘结剂均匀滴加入所述的混合粉体中，然后将制得的陶粒进行陈化、焙烧后得到所述的稀土氧化物粉煤灰陶粒。本发明所述的高荷重软化温度的稀土氧化物粉煤灰陶粒的制备方法添加稀土氧化物制备的粉煤灰陶粒具备更高的荷重软化温度，较未添加稀土氧化物的陶粒荷重软化温度提高10％以上。
