| 摘要 |
The invention relates to refractory branch of industry and can be used for the production of refractory articles based on chrome oxide, having high air brick strength, insignificant shrinkage at burning and increased heat stability and used in plants for production of fiberglass. The task of the invention is the creation of articles, having high air brick strength, heat stability and low shrinkage at burning. A furnace charge for the production of chromium oxide refractory contains chrome oxide, solid solution of TiOin CrOwith content of 85-95 % of particles less than 10 micrometers, solid solution of TiOin CrOin a form of grains, zirconium dioxide, titanium dioxide, dispersed iron, organic binder. |
