Abstract

The invention discloses a zirconium mullite boron nitride carbon side sealing plate which comprises the following components (in percentage by mass): 5-30% of zirconium mullite, 10-80% of hexagonal boron nitride, 1-20% of an additive, 0.5-5% of graphite, 0.1-5% of an (external) carbon fiber and 5-20% of a carbon binding agent (external). A manufacturing method of the zirconium mullite boron nitride carbon side sealing plate comprises the following steps: premixing the hexagonal boron nitride, the graphite, the carbon fiber and a part of the zirconium mullite so as to obtain powder A, uniformlystirring monomer boron with the carbon binding agent so as to obtain a composite binding agent B; putting the zirconium mullite of different granules into a mixing machine, adding the composite binding agent B, uniformly stirring and mixing, sufficiently mixing with the powder A so as to obtain a uniform mixed material, ageing the mixture, and carrying out normal-temperature molding; carrying outhigh-temperature carbonization, soaking treatment and annealing, and further carrying out grinding on a grinding machine, thereby obtaining a double-roller thin cast side sealing plate. The zirconiummullite boron nitride carbon side sealing plate disclosed by the invention has the characteristics of being low in friction coefficient, high in strength, good in wearing resistance, good in thermalshock resistance, good in corrosion resistance, small in investment equipment, low in cost, and the like.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials and high-temperature engineering refractory ceramics, and relates to a zirconium mullite boron nitride carbon side sealing plate and a manufacturing method. Background technique [0002] Pair-roll thin strip continuous casting is a near-net shape continuous casting. Thin strip continuous casting consists of two water-cooled rolls rotating in opposite directions and a pair of side sealing plates to form a molten pool or crystallizer. Use the submerged nozzle to inject molten steel into the molten pool through the flow distributor. The molten steel solidifies on the surface of the water-cooled roll. The gap between is squeezed out. Side sealing process and side sealing plate are one of the core technologies of thin strip continuous casting. The thin strip continuous casting process requires the ceramic refractory material of the side sealing plate to have excellent comprehensive pr...
