With the the world metallurgical industry, especially the rapid development of the steel industry, metallurgical industry, refractory increasing, the metallurgical industry, high-tech application and promotion makes many high-grade refractory applications become more and more widely abroad in this On the one hand the forefront. The experimental subjects for the actual situation of the domestic steel industry, of domestic corundum its micronized series of studies, the experimental work of corundum based self-flow castable. Paper work done at home and abroad, in-depth, carefully elaborated, and the basis of previous research, the whole experiment is divided into without microsilica system and containing microsilica system. Which has an important role in research on the application and promotion of future domestic corundum based self-flow castable without microsilica Department of artesian castable. In this study, three-step process: First, zeta electric potential instrument of alumina powder, silica powder, cement, and corundum powder characteristics, zeta electric potential instrument and absolute NDJ-1 viscometer constitute artesian castable matrix zeta potential and viscosity measurement and analysis. Finally, mobility and physical properties of self-flow castable experiment and analysis. The entire experiment carried out in accordance with the no microsilica system and containing microsilica system. Drawn a corundum artesian castable in accordance with the above-mentioned experimental methods are essential conditions: the total amount of the fine powder of the corundum artesian castables (-0.044mm) should be less than 35%; of Andreassen formula without microsilica system wide end q value and the narrow end of q values ??were 0.23 and 0.32, the optimum amount of alumina powder, cement is 7%, 4%, and the dispersing agent used for the modified sodium polyacrylate is preferably, and in the containing microsilica in Andreassen formula q value and the narrow end of the butt end q values ??were 0.21 and 0.29, the optimum amount of addition of alumina powder, silica powder and cement is 6%, 2% and 4%, the best combination of sodium tripolyphosphate and sodium hexametaphosphate as a dispersant. The experimental law also applies to all of the bauxite-based gravity, summed up the basis of experiments on the the corundum gravity castable castable. Also the preliminary groundwork containing magnesia materials such as magnesia, spinel self-flow castable experimental work. Thus the experiment has a certain significance and application value.
