Process method for preparing compact calcium dialuminate refractory clinker by one-step method
The invention relates to a process method for preparing a compact calcium dialuminate refractory clinker by a one-step method. The compact calcium dialuminate refractory clinker comprises the following components in percentage by weight: 76.11-77.68% of Al2O3, 20.89-21.32% of CaO and 1-3% of micro powder A. The relative density ranges from 91.6% to 93.9%, and the apparent porosity ranges from 3.7%to 4.9%. The preparation method comprises the following steps of: (1) respectively grinding bauxite, limestone and micro powder A, and mixing, and (2) pressing the mixed material into green pellets,and calcining to obtain clinker. The A micro powder is used as a sintering promoter; in the calcining process, the micro powder A is subjected to solid solution in a calcium dialuminate phase to forma solid solution; the sintering activity of the calcium dialuminate phase is improved, and the growth of the calcium dialuminate phase is promoted, so that the compact calcium dialuminate refractory clinker can be obtained under the conditions of lower calcination temperature and shorter heat preservation time, the production energy consumption is effectively reduced, the production efficiency isimproved, and the energy conservation and emission reduction are promoted.
一种一步法制备致密二铝酸钙耐火熟料的工艺方法，其成分按重量百分比含AlO76.11~77.68%，CaO 20.89~21.32%，A微粉1~3%；相对密度为91.6~93.9%，显气孔率为3.7~4.9%；制备方法为：（1）将铝矾土、石灰石和A微粉分别磨细后混合；（2）将混合物料压制成生球，然后进行煅烧制成熟料。本发明采用A微粉作为促烧结剂，在煅烧过程A微粉固溶到二铝酸钙相中形成固溶体，从而提高了二铝酸钙相的烧结活性，促进二铝酸钙相的长大，从而可在较低的煅烧温度和较短的保温时间条件下获得致密二铝酸钙耐火熟料，有效降低了生产能耗，提高了生产效率，促进了节能减排。
