在铝和铝合金的直接水冷连续铸造过程中,结晶器内金属液面水平的波动,直接影响着铸锭的内部及表面质量。实现金属液面的自动控制,是改进连续铸造工艺的一个重要环节。目前,国内外连续铸造工艺中有的采用电气和机械传动方式控制液面,有的采用同位素装置。前者操作困难,控制不够灵敏;后者设备费用昂贵。

During the continuous water-cooled continuous casting of aluminum and aluminum alloy, the level fluctuation of the liquid level in the mold directly affects the internal and surface quality of the ingot. Automatic control of the metal surface is an important step to improve the continuous casting process. At present, some domestic and foreign continuous casting process using electrical and mechanical transmission control of the liquid surface, and some use of isotope devices. The former is difficult to operate and the control is not sensitive enough. The latter is expensive.
