冷拉型钢生产工艺中单控和双控有什么不同？
冷拉型钢通过许多生产工艺步骤进行加工和成型。我们熟悉及时的单孔然后是双重控制。尽管可以获得冷拉型钢，但两种生产工艺之间存在很大差异。如果您想更多地了解不同之处，则需要比较冷拉型钢的单孔和双孔控制。
Cold drawn steel is processed and formed through many production process steps. We are familiar with timely single hole and then dual control. Although cold drawn steel can be obtained, there is a big difference between the two production processes. If you want to know more about the difference, it is necessary to compare the single hole and double control of cold drawn steel.
冷拉型钢进行冷拔时，所谓的单一控制就是用冷拔速率或冷拔应力来控制整个过程。双控制是同时施加冷拔速率和冷拔应力的控制方法。相比之下，单孔生产方法在施工过程中相对简单，但是无法对材料不均匀的钢筋进行逐一测试，因此不能保证冷拔的质量。但是，双重控制是不同的。只要双重控制控制力满足要求并且冷拔率不超过允许值，就可以认为是合格的。但是，如果已达到冷拔速率，而冷拔应力尚未达到控制应力，则应降低该产品的强度。
When cold-drawing steel is cold-drawn, the so-called single control is to control the whole process with cold-drawing rate or cold-drawing stress; while dual control is the control method in which the cold-drawing rate and cold-drawing stress are applied simultaneously. In contrast, the single-hole production method is relatively simple during construction, but it is impossible to test one by one for steel bars with uneven materials, so the quality of cold drawing cannot be guaranteed. However, the dual control is different. As long as the dual control control force meets the requirements and the cold drawing rate does not exceed the allowable value, it can be considered qualified. However, if the cold-drawing rate has been reached and the cold-drawing stress has not yet reached the control stress, then this product should be reduced in strength.
