在连铸机浇钢过程中,当中间罐滑动水口的滑板砖因粘附钢水而造成滑板滑动动作延误时,将引起结晶器内钢水平面的波动,这将使连铸坯中生产夹渣等缺陷。为使在连铸过程中滑板的动作圆滑而流畅,日本的住友金属公司和歌山钢铁厂采用了一种在滑板的控制信号上附加一个振动信号的方法,使滑板以一定的频率振动,从而解决了滑板粘钢延时问题,即解决了结晶器内钢水面的波动问题。
In the process of pouring steel in the continuous casting machine, when the skateboard brick in the sliding groove of the middle tank slides due to the sticking of the molten steel, the fluctuation of the steel level in the mold will be caused, which will make slag production in the slab defect. In order to smooth and smooth skateboarding during the continuous casting process, Sumitomo Metal Co., Ltd. and Wakayama Steel Works of Japan adopted a method of attaching a vibration signal to the control signal of the skateboard to make the skateboard vibrate at a certain frequency, thereby solving Skateboard sticking steel delay problem, that is, to solve the problem of fluctuations in the molten steel surface.
