Abstract

The invention discloses a long nozzle protective glaze, which comprises the following components in weight percentage: 20-30% of quartz, 10-20% of burnt gemstone, 10-15% of potassium feldspar, and 10-15% of Suzhou soil ; 20~30% silica sol, 1~2% dispersant and 5~15% water. At the same time, the invention also discloses a preparation method of the above-mentioned shroud protective glaze. The protective glaze for the shroud provided by the invention has good ductility, spreads smoothly on the shroud, has high bonding strength, good glaze and film forming properties, and good oxygen isolation, and significantly improves the service life of the shroud.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and in particular relates to a shroud protective glaze and a preparation method thereof. Background technique [0002] The shroud is used between the ladle and the tundish to protect the molten steel from secondary oxidation and prevent the steel from splashing. The currently used shrouds are generally made of aluminum carbon, and the graphite in them can improve the slag resistance and thermal shock resistance of the shroud, but it is easy to be oxidized, causing the shroud structure to loosen and collapse, and the material to fail. Contents of the invention [0003] Object of the invention: The object of the invention is to provide a shroud protective glaze to address the deficiencies of the prior art. [0004] Another object of the present invention is to provide a method for preparing the above shroud protective glaze. [0005] Summary of the invention: In order to achiev...
