Carbon-free submersed nozzle lining material and preparation method thereof
The invention relates to the technical field of refractory materials, and discloses a carbon-free submersed nozzle lining material and a preparation method thereof. The carbon-free submersed nozzle lining material consists of the following raw materials in parts by weight: 30-50 parts of zirconium mullite, 15-25 parts of a porous material, 5-10 parts of white corundum 80 #, 10-15 parts of white corundum with a size of 200 meshes, 10-15 parts of white corundum with a size of 320 meshes, 0.5-1 part of silicon carbide, 0.5-1 part of boron glass, 0.5-1 part of boron nitride and 2-10 parts of liquid phenolic resin. A submersed nozzle prepared from the submersed nozzle lining material provided by the invention has relatively high strength and relatively good thermal shock resistance; and the submersed nozzle prepared from the submersed nozzle lining material does not recarburize molten steel and does not have a nodulation phenomenon.
本发明涉及耐火材料技术领域，公开了一种无碳浸入式水口内衬材料及制备方法。无碳浸入式水口内衬材料由以下重量份数的原料组成：锆莫来石30‑50份，多孔材料15‑25份，白刚玉80#5‑10份，白刚玉200目10‑15份，白刚玉320目10‑15份，碳化硅0.5‑1份，硼玻璃0.5‑1份，氮化硼0.5‑1份，液体酚醛树脂2‑10份。本发明提供的浸入式水口内衬材料制备的浸入式水口具有较高的强度、较好的热震稳定性，采用其制备的浸入式水口对钢水不增碳、且没有结瘤现象出现。
