In the continuous casting production process, the sliding nozzle system is an important control device of molten steel in the casting process of a continuous casting machine, and can accurately adjust the flow of the molten steel from a steel ladle to a tundish, so that the inflowing molten steel and the outflowing molten steel are balanced. Although the sliding plate is required to have the characteristics of high temperature resistance, high strength, good erosion resistance, good thermal shock resistance, high oxidation resistance, small creep deformation and the like, in the continuous casting process, the sliding plate is repeatedly rubbed in the opening and closing operations of pulling and sliding, and losses such as fluffing, oxidation, hole expansion and the like often occur, so that the integrity of a smooth and compact layer on the surface of the sliding plate is damaged, the frictional resistance between the upper sliding plate and the lower sliding plate is further increased, the flexibility of the sliding operation and the accuracy of molten steel flow control are reduced, the service life of the sliding plate is shortened, and even steel clamping and steel leakage accidents occur.
The function of slide coating is in being covered the protection by the coating with the slide, and coating itself fills the gas pocket on slide surface, make the slide table compacter, improve the erosion resistance of slide, improve the oxidation resistance of slide, slide coating still has the lubricity, reduce the frictional force when the slide draws smooth, wearing and tearing when reducing the slip of slide, make the laminating of glide plane inseparabler, prevent that the glide plane from pressing from both sides steel, bleed-out, increase the number of times that draws smooth of slide, the life-span of extension slide. Chinese patent CN106189386A (a sliding plate coating and its preparation method) discloses a sliding plate coating using expanded graphite and graphene as solid powder, although graphite has excellent slag erosion resistance, good lubricating property and high melting point, the high temperature oxidation property of graphite carbon material is poor, crystalline flake graphite is significantly oxidized at a temperature above 400 ℃, which results in rapid consumption of graphite lubricating coating on the surface of the sliding plate, the specific surface area of expanded graphite and graphene is large, and the oxidation risk is higher. CN102660162A (slide plate protective coating for sliding gate in steel-making continuous casting equipment) discloses a coating with scale graphite and molybdenum disulfide as main solid components. CN110066532A (preparation of high-performance graphene skateboard coating and process method thereof) discloses a coating with alumina, magnesia, graphene and carbon black as main solids. Both the carbon raw materials contain crystalline flake graphite or graphene and carbon black, the problem of high-temperature oxidation cannot be solved, and the technical risk of steel clamping and the like is increased rapidly due to the formation of pores along with oxidation and decarbonization. CN102660370A (high-temperature lubricant and preparation process thereof) discloses a high-temperature lubricant which takes graphite micro powder, xanthan gum, hexagonal boron nitride and aluminum dihydrogen phosphate as main solid components, in order to overcome the problem of graphite oxidation, nickel plating treatment is carried out on the graphite micro powder, but the nickel plating treatment process is very complicated, waste liquid pollutes the environment, and subsequent waste liquid is difficult to carry out innocent treatment, so that the slide plate coating process has long flow, high production cost and difficult innocent treatment, runs contrary to the trend of environmental protection, and limits the large-scale application of the slide plate coating. CN103509641A (hexagonal boron nitride-based sliding plate lubricant and preparation method thereof) discloses a sliding plate coating with hexagonal boron nitride, carbon black and silica sol as main components, and although hexagonal boron nitride has a graphite-like layered structure and has good lubricating property, it is used as a sliding plate coating and oxidized into boron oxide at high temperature, inevitably resulting in a decrease in self-lubricating effect.
