In certain conditions, hot cracks eccurred in continuous casting billets of a 0.45% C steel. It was observed that such cracks were practically healed by rolling when the reduction ratio attained about four. Inclusion clusters and segregation of phosphorous in the neighbourhood of the above cracks as elongated streaks were often present and aligned with the rolling direction. In view of these, dark etching lines resembling cracks could occur on deep macro-etching. This sort of inhomogeneity hardly affected the...

In certain conditions, hot cracks eccurred in continuous casting billets of a 0.45% C steel. It was observed that such cracks were practically healed by rolling when the reduction ratio attained about four. Inclusion clusters and segregation of phosphorous in the neighbourhood of the above cracks as elongated streaks were often present and aligned with the rolling direction. In view of these, dark etching lines resembling cracks could occur on deep macro-etching. This sort of inhomogeneity hardly affected the longitudinal mechanical properties of therolling products, although the transverse ductility was appreciably lowered.

在工艺条件不适当时,45钢连铸坯在高温下会产生内部裂纹,当压延比近于4时,裂纹即可焊合。而富集在裂纹上的夹杂物和偏析元素,则被变形并沿轧制方向分散。当这种分散程度不太大时,酸洗后会在那里腐蚀出和裂纹形状相似的沟槽。这种缺陷对纵向力学性能没有影响,但使横向的塑性下降。

The high speed traverse is one of the keys of the high speed spinning.The highspeed traverse mechanism recommended in this paper is a device with multi-thread cam.It has many advantages,for example,impulse and wear are reduced,and radiation ofheat is fine.However,the best advantage is that swelling edge of the package may beprevented.In order to provide theoretical basis for design of this mechanism,the mainparameters of multi-thread cam and traverse guide have been analysed in this article.Besides,we have derived a general expression of the centre line of cam channel,so thatwe would be able to make the cam with numerical control machine tools.The result of practice shows that the work of this device is reliable and the perfor-mance is good.This mechanism can be used not only for high speed spinning machine,but also for spinning machine of usual speed.

高速导丝是高速纺丝的一大关键。本文讨论的多头凸轮式导丝机构,具有冲击少、磨损小、散热好等优点,而其最为独特的好处是能够防止筒子的凸边。文中对多头凸轮和导丝器的主要参数进行了分析研究,为机构的设计提供了理论依据。考虑到要用数控机床制造多头凸轮,专门列出了沟槽曲线的通式。实践证明,多头凸轮式导丝机构工作可靠,性能良好,不仅可以用于高速纺丝机,也可用在常速纺丝机上。
