We developed a method for obtaining silicone bonds for refractory materials based on nonhydrolyzed ethyl silicate, silicone resins, and organic adhesive component. Using corundum and periclase refractories as examples we demonstrated that use of the new bonds contributes to a significant strengthening of the materials in the range 20-900°C, and they are therefore prospective for preparing unfired refractories. The use of bond ensures densification and strengthening of corundum refractories, while simultaneously reducing the shrinkage, and leads to an increase in the stabilization of the high-temperature strength of the articles and a reduction in their wettability by molten steel. It is shown that the new oxide materials may be obtained in the production of tiles for the gate valves of steel-casting ladles. [ABSTRACT FROM AUTHOR] |
