Straightening roll for straightening device in annealing furnace as well as preparation method and application of straightening roll
The invention relates to the technical field of silicon steel straightening, in particular to a straightening roll for a straightening device in an annealing furnace and a preparation method and application of the straightening roll. According to the straightening roll for the straightening device in the annealing furnace designed by the invention, the straightening roll for the straightening device in the annealing furnace is a high-temperature-resistant ceramic roll, and the high-temperature-resistant ceramic roll is prepared from the following raw materials in percentage by weight: 85%-90% of silicon nitride micro powder and 10%-15% of a binding agent. Compared with a traditional metal straightening roll, the straightening roll for the straightening device in the annealing furnace adopts the high-temperature-resistant ceramic straightening roll, the affinity with coating in the furnace is low in the process of straightening silicon steel in the high-temperature annealing furnace, the coating is not prone to being bonded, and the high-temperature-resistant ceramic straightening roll has good thermal stability and strength and can be used for straightening the silicon steel in the annealing furnace. And deformation and abrasion are not easily caused in a high-temperature annealing furnace.
本发明涉及硅钢矫直技术领域，尤其涉及一种退火炉内矫直装置用矫直辊及其制备方法和应用。本发明所设计的退火炉内矫直装置用矫直辊，按重量百分比计，在退火炉内的矫直装置所用的矫直辊采用耐高温陶瓷辊，所述耐高温陶瓷辊由以下原料制备而成：氮化硅微粉85％～90％和结合剂10％～15％。与传统的金属材质矫直辊相比，本发明的退火炉内矫直装置用矫直辊采用耐高温陶瓷矫直辊，在高温的退火炉中矫直硅钢过程中与炉内涂料的亲和力低，不易粘结涂料，而且该耐高温陶瓷矫直辊具有较好的热稳定性和强度，在高温的退火炉中不易变形和磨损。
