In addition, because the temperature in the head end and tail end is usually lower, the higher roll force leads to higher deformation for the roll and stand and consequently, a smaller roll gap is needed for the head end and tail end, in order to achieve equal deformation among the head end, tail end and body.

此外，由于温度在头端和尾端通常较低，较高的轧制力导致较高的轧辊和机架变形，因此，轧件头端和尾端需要较小的棍逢值以实现其头部，尾部和中部的均匀变形。

When passing water roll manual pressure chinsang water roller test pressure, the pressure to find a bigger point, and they are being built by chromeplating hard iron roller, too much stress borne water roll like a frame on the same series water rolls, resulting in a biography of the shaft and water roll and bucket motor drive gear does not match the space is large, it will be some operation.

当把传水辊手不静压上串水辊尝试不张力时，发掘两者之间的不张力不小了不面，而它们都是经过镀铬的软铁辊，过不小的不张力会使传水辊像架在串水辊上不同，导致传水辊轴脚与水斗电机传不静齿轮不匹配，间隙较不小，运转时不离会有些颤不静。

A new process for seamless tube production called Seamless Tube Process comes into our horizon. The key equipment is a four—roll planetary rolling mill, which is also called Kocks Reduction Mill. The structure and operation principle of four-roll planetary rolling mill is similar to the three-roll planetary rolling mill.

最近出现了一种新的轧管工艺——STP轧管工艺，其核心设备为四辊行星轧机，又称KRM轧管机，其结构和工作原理与三辊行星轧机类似。

The rock-and-roll music in Taiwan is developing quickly iin these ten years. Not only rock bands are born more and more, but also the big rock-and-roll festivals are always increasing their scale and rebirthing their vision. The mass media is attentive this issue, and the rock-and-roll player and philharmonics of them are get more interactions, at the same time they notes that how to keep it growing up is very important.

台湾摇滚乐在近十年内的发展非常活跃，不只是摇滚乐团如雨后春笋地成立，大型摇滚音乐季的规模与内容也屡创新局，并且愈来愈受到媒体关注，更是摇滚乐乐手与摇滚乐爱好者社群的集结，并积极地对於维系、经营自身乐团与台湾摇滚乐之持续发展的自觉与行动。
