Application of Water-hard Aluminum Oxide for Amorphous Refractory Binders
Recently, the China Non-ferrous Metals Industry Association organized an appraisal meeting for Zhengzhou Research Institute of Aluminum Corporation of China in the Zhengzhou Research Institute of China Aluminum Corporation, which was completed by the China Non-Ferrous Metals Industry Association. The appraisal committee heard the report of the research group and reviewed relevant technical documents. After serious discussion, the experts believed that the project successfully used hydraulic alumina as a binder for unshaped refractory materials. Its technical innovation points are as follows: (1) Hydraulic hydration hardening rate control technology was developed for hydraulic alumina. The hydration hardening rate can be controlled within 30 minutes to 2 hours. The rheological behavior of the hydraulic alumina slurry in the composite system was systematically studied, and the corresponding additives were achieved. The purpose of controlling the initial setting time of hydraulic alumina composite system; (2) systematically studied the effect of hydraulic alumina on the performance of monolithic refractories. The results show that hydraulic alumina can effectively improve the slag resistance of refractories. High temperature performance and life. The technology of this project has reached the international advanced level, with good social and economic benefits, and it is easy to apply in industry.
