It makes possible and practicaI the manu-facture of spiral flight and other products with good flexibiiity, high efficiency,and Iow consumptiOn,In this paper,the theoretical study on the processes of cold-rolling with conical rollers.

它利用楔形轧制和异步轧制的若干特点，以构成一个新的轧制过程，提供了高效、低耗和柔性加工钢带和螺旋叶片的可能性和现实性。

The development of the shape theory has produced a great effect on the strip rolling technique. But with the increasing demands of the quality of rolling strip production in the market, the weakness has evidently appeared in the conventional theory.

板形理论的发展对板带轧制技术的发展起到了很大的作用，但是随着市场用户对轧制带钢产品质量的要求越来越高，传统的理论已表现出明显的局限性。

According to the 1999 survey is not complete, the current national production of fake and shoddy construction steel production enterprises amounted to one thousand, throughout 21 provinces, autonomous regions, the annual production capacity of 5 million tons, of which the vast majority of production "of steel in" and use "of the steel to" unburnt earthenware rolled Luowengang, W-renewable steel.

据1999年的不完全调查，目前全国生产假冒伪劣建筑钢材的生产企业达一千余家，遍及21个省、自治区，年生产能力达500万吨以上，其中，绝大多数是生产"地条钢"和用"地条钢"坯轧制螺纹钢、W形再生钢。

Reportedly, in recent years, regional manufacturing and selling counterfeit and shoddy steel repeated offences, particularly regional production "of steel in" and use "of the steel to" unburnt earthenware Luowengang rolled steel and other construction issues very prominent.

据了解，近年来，区域性制售假冒伪劣钢材的违法行为屡禁不止，尤其是区域性生产"地条钢"和用"地条钢"坯轧制螺纹钢等建筑钢材的问题十分突出。

Because be mingled with of the sulfide in rolling process steel and rolled steel are coinstantaneous,be out of shape , its want to the influence of the mechanical function of direction of rolled steel length relatively blame rolling direction is mechanical the impact of function is little much.

由于轧制过程钢中硫化物夹杂和钢材同时发生变形，其对钢材长度方向的力学性能的影响要较非轧制方向力学性能的影响小得多。

However, semi-steel is made of 10 ~ 20% cementite and pearlitic matrix, there exists no pellet-shaped graphite, so sticking is easy to happen to it, which is not expected dunng rolling.

然而半钢材质是由10-20％渗碳体及珠光体基体所组成，其内不存在球状石墨，所以半钢材质容易产生粘钢现象，这是轧制过程所不希望的。

Automatic Width Control technique for 1 450 mm hot strip rolling mill in Panzhihua New Steel and Vanadium Co Ltd;2. Advantage and disadvantage of coil box in hot strip rolling mill were analyzed in details according to the producing experiences.

分析了带钢热连轧中热卷箱的优势以及存在问题，并提出了选用热卷箱的综合评估方法，即应综合衡量建设场地、投资、轧制速度、轧制钢种、轧制节奏、节能降耗、轧件温度和表面质量等。

The precision of gauge control of hot-rolled strip is directly affected by the calculating precision of rolling force model, where the rolling pressures in the models are mostly decomposed and become the product of the influence coefficient in stress state arid resistance to deformation.

轧制力模型的计算精度直接影响热轧带钢厚度控制精度，目前大多数轧制力模型都把轧制压力分解成应力状态影响系数和变形抗力的乘积。

In order to roll round billets with accurate roughing shapes by a three-high roughing mill and stabilize production, a flexible pass design method was used to optimize the traditional conjugate pass through the distortion design of the bottom, side wall and pressure difference of the pass, realizing the application of the conjugate round pass on the three-roll mill.

为轧制料形尺寸准确的圆料、稳定生产，采用变通孔型设计方法对共轭孔型进行优化设计，通过对共轭孔型槽底、侧壁、压力差的变形设计，实现了共轭圆孔型在三辊粗轧机上的应用，轧槽咬钢顺利，成品圆料容易控制，完全满足后续工序的要求，同时减小了轧线的轧制事故，单套轧辊的轧制量可提高60%以上，取得了良好的经济效益。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
