内容简介

For the proper use of micropowders in castables, slurries and fired samples were prepared with two kinds of corundumspinel micropowders(D and G). The effects of the solid content and disperser WSM-R1 on the rheological properties of the slurries were studied. The sintering properties and the slag corrosion resistance of the fired samples were also researched.The results show that: the slurries all show pseudoplastic rheological characteristics. With the same solid content, the slurry with micropowder G has higher initial viscosity than that with micropowder D. Disperser WSM-R1 significantly reduces the initial viscosity of the two slurries and plays a more obvious dispersing effect on the slurry with micropowder G. The fired sample with micropowder G has higher bulk density, lower apparent porosity and better corrosion resistance than that with micropowder D.
