冷拉型鋼生產(chǎn)工藝中單控和雙控有什么不同？

冷拉型鋼通過許多生產(chǎn)工藝步驟進行加工和成型。我們熟悉及時的單孔然后是雙重控制。盡管可以獲得冷拉型鋼，但兩種生產(chǎn)工藝之間存在很大差異。如果您想更多地了解不同之處，則需要比較冷拉型鋼的單孔和雙孔控制。

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.

冷拉型鋼進行冷拔時，所謂的單一控制就是用冷拔速率或冷拔應(yīng)力來控制整個過程。雙控制是同時施加冷拔速率和冷拔應(yīng)力的控制方法。相比之下，單孔生產(chǎn)方法在施工過程中相對簡單，但是無法對材料不均勻的鋼筋進行逐一測試，因此不能保證冷拔的質(zhì)量。但是，雙重控制是不同的。只要雙重控制控制力滿足要求并且冷拔率不超過允許值，就可以認為是合格的。但是，如果已達到冷拔速率，而冷拔應(yīng)力尚未達到控制應(yīng)力，則應(yīng)降低該產(chǎn)品的強度。

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.
