锡槽直线电机
直线电机模组是一种将电能直接转换成直线运动机械能的装置，当直线电机三相绕组通入电流时，产生“行波磁场”，位于“行波磁场”中的导体因切割磁力线而感应出电流，电流与磁场相互作用便产生电磁力，在锡槽中，这种电磁力推动锡液运动，通过调节电机的参数，就可方便的控制锡液流动的方向与速度。 The linear motor influences the tin flow in the tin bath by means of an electromagnetic field, which generates a magnetic force on the tin surface. As a result, the molten tin circulates along the flux lines of the magnetic field, moving from the middle of the tin bath towards its edges and back. Thus, tin flows are generated, which facilitate balancing the temperature profile of the tin all over the glass ribbon. Moreover, the linear motors can be used at the dedrossing pockets to clean the surface of the liquid tin of dross (tin oxide) at the end of the tin bath. A second positive effect of the linear motors at the dedrossing pocket is the circulation of the tin at the exit end by virtue of the angled return channel. During heat-up of the tin bath the linear motors are used to homogenise the tin temperature, as well as to clean the tin。
