利用加热炉模拟、动态再结晶以及热模拟等试验方法以及扫描电镜、金相显微镜等分析观察手段对无取向硅钢边裂的成因进行了探讨。结果表明,长时间加热使得板坯边部晶粒异常长大,晶界氧化并脱碳,轧制过程中边部温度过低,动态再结晶过程变弱,使得板坯边部延伸性能变差,是导致硅钢边裂的主要原因。建议通过适当降低铸坯加热温度、缩短保温时间、提高终轧温度来改善硅钢边裂缺陷。 The behaviors of high temperature oxidation,dynamic recrystallization,and hot ductility,microstructure evolution were investigated on the non-oriented electrical steel sheets to discuss the formation of edge crack.The key causes of cracking was found to be the coarse as-cast microstructure,grain boundary oxidation and decarburization in reheating furnace,as well as reduced temperature at strip edge region during hot rolling process resulting in reduced hot ductility and lack of enough dynamic re...

研究了激光加热辅助圆盘剪高速切割技术,以解决现有冷轧生产线硅钢切边技术存在的微裂纹、应力、毛刺和边浪等问题。建立了激光加热温度场有限元分析模型,根据生产线上圆盘剪加工的实际过程,探讨了数值模拟中热源的加载形式,研究了激光对板材进行辅助加热时各个工艺参数如激光功率、光斑尺寸以及激光入射角度对切割工艺的影响,并通过实验对工艺参数进行了优化。最后,进了验证实验。实验结果显示:当激光加热点运动至圆盘剪刃口位置时,温度为100℃左右,此时材料硬度降低到原有硬度的70%~80%,降低了切削力,减少了圆盘剪的磨损,可有效提高圆盘剪的寿命。 Laser assisted trimmer side cutting technology was studied to overcome the problems such as micro cracks,stress,burrs and edge waves existing in a cold rolling production line of silicon steel side cutting.A finite element analysis model for the laser hearting temperature field was established, the loading form of a heating source was determined and influences of various processing parameters like laser powers,spot sizes,and laser incident angles on laser assisted heating sheet materials were di...

热卷箱位于热连轧带钢生产线粗轧与精轧机之间,是热连轧生产中比较理想的中间保温设备。由于取向硅钢变形温度区间较窄,在生产中易出现边裂现象,同时中间坯的边部温度难于得到保证,因此一般不采用热卷箱设备生产,限制了传统热连轧生产线产品开发的品种。通过合理优化热卷箱控制工艺参数,解决了某厂传统热连轧生产线用热卷箱生产取向硅钢的边部质量问题,成功地生产出取向硅钢带。 The hot coil-box is an ideal heat retaining apparatus for hot rolling,lined between roughing mill and finishing mill. But oriented silicon steel has a narrow deformation temperature range,so that the edge crack easily occurs and it is difficult to insure the temperature of the intermediate blank. Therefore,the hot coil-box is rarely used in producing oriented silicon steel,which restricts the product development of the traditional hot rolling line. The article reasonable optimized process parame...
