Resin combined tundish working lining anti-oxidation coating
The invention relates to the technical field of refractory coatings, in particular to a resin combined tundish working lining anti-oxidation coating. The coating contains low-temperature glass powder, solid water glass, caustic-burned magnesia powder, white dextrin, sodium tripolyphosphate, hydroxypropyl methyl starch ether, ferrosilicon slag powder, silica fume, silicon carbide source gas and deionized water; the following components in parts by weight are as follows: 16-20 parts of low-temperature glass powder, 6-11 parts of solid water glass, 27-33 parts of caustic-burned magnesia powder, 2-4 parts of white dextrin, 2-4 parts of sodium tripolyphosphate, 1-2 parts of hydroxypropyl methyl starch ether, 28-35 parts of ferrosilicon slag powder, 3-7 parts of silica fume, 50-85 parts of silicon carbide source gas and 57-62 parts of deionized water. The problems that in the prior art, carbon loss under the working condition of high-temperature baking of the working lining cannot be avoided, the depth of a decarburized layer is large, the strength of the working lining is low, the service life of the working lining is short, a packet collapse accident is likely to be caused when decarburization is serious, and the safety risk is high can be effectively solved.
本发明涉及耐火涂层技术领域，尤其为一种树脂结合中间包工作衬抗氧化涂层，包括低温玻璃粉、固体水玻璃、轻烧镁粉、白糊精、三聚磷酸钠、羟丙基甲基淀粉醚、硅铁渣粉、微硅粉、碳化硅源气体以及去离子水，且各成分按照重量比分别为：低温玻璃粉16～20份，固体水玻璃6～11份，轻烧镁粉27～33份，白糊精2～4份，三聚磷酸钠2～4份，羟丙基甲基淀粉醚1～2份，硅铁渣粉28～35份，微硅粉3～7份、碳化硅源气体50～85份以及去离子水57～62份，本发明可以有效地解决了现有技术无法避免工作衬高温烘烤工况下的碳流失，脱碳层深度较大，工作衬的强度和使用寿命较低，脱碳严重时容易造成蹋包事故，安全风险较高的问题。
