A serials of problems of miss position of roll, easy damage of guide and guard, scuff mark of piece were common during oval piece entering round pass by 2-h horizontal mill.

I claim I have a nice formula for the area, because this is vertical and this is horizontal h so this length here is u3, this length here is h.

我有个很好的公式来做这个问题，因为这个是竖直的，这个是水平的,所以这个长度这里是u3，这个长度这里是。

The speed is then about 425 miles per hour so the horizontal component 300mi/h and the vertical component is also 300.

假定速度为425英里/时,那么水平分量,就是。
