摘要
取向硅钢因其高磁导率、低矫顽力和大电阻系数等特性,被广泛应用于大中型变压器和大型电动机铁芯的制造。因取向硅钢性能和成分控制严格,生产工艺复杂,故其产品代表了钢铁企业特殊钢生产的最高水平。本文介绍了新钢公司卷板厂1580热连轧线生产取向硅钢过程中出现的窄尺问题,研究了取向硅钢产品的特点,分析了热轧过程中的组织转变,并结合生产实际提出了改进措施。通过对加热炉钢坯加热模式、粗轧轧制策略、精轧轧制工艺、二级模型等方面的优化和改进,取向硅钢窄尺情况明显好转,提高了产品的成材率和市场口碑。
The oriented silicon steel is widely used in the iron core manufacture of large and mediumsized transformers and large motors because of its high permeability, low coercivity and large resistance coefficient. Due to the performance and composition control of oriented silicon steel is strict, the production process is complex,therefore, its products represent the highest level of special steel production in iron and steel enterprises. This paper introduces the problem of narrow gauge in the production process of oriented silicon steel in 1580 hot continuous rolling line of the coil plant of Xingang, studies the characteristics of oriented silicon steel products, analyses the microstructure transformation in the hot rolling process, and puts forward improvement measures in combination with the actual production situation.Through the optimization and improvement of steel billet heating mode in the heating furnace, rolling strategy of roughing, rolling process of finish rolling, secondary model and other aspects, the situation of oriented silicon steel narrow gauge has been improved significantly, and the product percent of pass and market reputation have been improved.
