Method of and apparatus for controlling the motion of a pouring ladle
摘要:
The pouring ladle can not only be tilted by a tilting drive and a cable around a permanent tilting axis in order to pour the molten metal in a mould, respectively to interrupt the pouring process, but the tilting axis can be lifted and lowered by a determined value by a lifting drive. By lifting and lowering the tilting axis, the tilting motion of the pouring ladle takes place approximately in the center of gravity of the molten metal. This permits to avoid compensating streams and wave motions of the molten metal when the pouring ladle tilts forward and backward and more definite and reliable processes are achieved, capable to be controlled, at the start of pouring and at the time of terminating the pouring. The lifting drive and the tilting drive can be utilized for further lifting the pouring ladle in order to advance the pouring ladle further toward the center of the mould at the first pouring process under holding a determined distance of security from the mould.
