Abstract
Description

[0002] The three major parts of continuous casting include the integral stopper rod, the long nozzle (long nozzle for large ladle) and the immersed nozzle. They need to be baked on site when used in the steel plant. In order to prevent the three major parts of continuous casting from being oxidized during on-site baking and use, the surface of the product should be coated with protective glaze, i.e. glaze. The configured glaze can be melted into glaze at a relatively low temperature (600-750℃), can be well spread on the surface of the product and maintain viscosity without major changes in a wide temperature range, which plays a role in protecting the graphite in the product from oxidation. The anti-oxidation glaze applied on the surface of the three major parts of continuous casting requires uniform thickness when applied, especially when the integral stopper rod and the immersed nozzle are baked with the tundish, the anti-oxidation effect of the anti-oxidation glaze, i.e. glaze, is particularly obvious.
