连续铸钢正在不断发展,并占有世界各地钢铁生产的日益增多部分。甚至一些小的或没有新的钢铁生产力量的企业,常规的浇注生产也在减少,而液态钢的转变过程采用连续浇注设备越来越多,因为它具有许多优点:改善质量,收得率高,节省能源。现在的发展目标是要达到更高的生产率—不降低质量标准。这就涉及到一个问题,在浇注过程中必须在相当于40m生产线上,将拉速为2m/min、250mm厚的板坯控制好凝固。 1.最佳电磁搅拌技术的应用 为了控制铸流凝固,最近引用了电磁场感应产生湍流的技术。现在电磁搅拌已广泛用在连续铸钢工艺中,计算机可用来使各不同子系统的变量相关。
Continuous casting is evolving and occupies a growing segment of steel production around the world. Even for those with little or no new steel production capacity, conventional pour-in production is declining and liquid steel is being converted using more and more continuous pouring equipment because of its many advantages: improved quality, high yield ,save energy. The goal now is to achieve higher productivity - without compromising quality standards. This involves a problem in the pouring process must be equivalent to the 40m production line, will pull speed of 2m / min, 250mm thick slab controlled solidification. 1. Optimal Electromagnetic Stirring Technology In order to control the solidification of cast iron, a recent technology that induces turbulence by electromagnetic field induction has been cited. Electromagnetic stirring is now widely used in continuous casting processes and computers can be used to correlate variables in different subsystems.
