According to above points, we concluded that although some parts of the weir plate have certain gas holes on the surface, it won't ill-effect the use functions.

基于以上几点，我们认为，此批堰板有部分存在表面气孔较多，但这不会对使用产生任何不良影响。

The application of this equipment will help the separation between steel and slag with obvious better performance in the steel liquid quality as compared with that of high aluminum weir plate.

有利于钢渣分离，提高钢液质量明显优于高铝质堰板净化钢水的作用。

The performance of hole-plate and overflow-weir liquid distributors have been measured and a proposal for the design of the two kinds of the distributors is given.

通过对孔板式和溢流堰式液体分布器性能的测定，提出了对该两种分布器设计的建议。

This invention provides a set of self-powered mechanical device, an auto-regulating movable weir-plate, a back-flushing buffer and lift-pull valve.

本发明提供一套自力式机械装置、自动调节活动堰板、反冲阻流器、提拉阀。
