连铸机板坯连铸结晶器电磁搅拌技术不管搅拌器的形式和安装方式如何,都采用行波磁场搅拌器。搅拌器一般采用超低频三相电源激磁,激发向一个方向行进的行波磁场,俗称直线磁场。其工作原理已在方坯连铸二冷区行波磁场搅拌器中已阐述,此处不再赘述。板坯连铸结晶器电磁搅拌根据搅拌器安装方式不同,主要有两种模式:水平旋转搅拌和向下直线搅拌。(1)水平旋转搅拌的配置特点。在结晶器两个宽面即F面(固定)和L面(可动)上配置一对行波磁场搅拌器,激发方向相反的两个行波磁场,在钢水中感生方向相反的两个电磁力,由于钢
Continuous casting machine Slab continuous casting mold Electromagnetic stirring technology Regardless of the type of agitator and how to install, adopt the traveling wave magnetic field agitator. Agitators generally use ultra-low frequency three-phase power excitation, excited to travel in one direction traveling wave magnetic field, commonly known as linear magnetic field. Its working principle has been described in the billet continuous casting two cold zone traveling-wave magnetic field mixer, not repeat them here. Slab Continuous Casting Mold Electromagnetic Stirring Depending on how the stirrer is installed, there are two main modes: Horizontal Rotation Stirring and Downward Straight Stirring. (1) Horizontal rotating stirring configuration features. A pair of traveling wave magnetic field agitators are arranged on the two wide faces of the mold, ie, the F face (fixed) and the L face (movable), and two traveling magnetic fields in the opposite directions are excited. Two opposite induced directions in molten steel Electromagnetic force, due to steel
