冷拉方鋼是在校直時(shí)會(huì)使用到壓機(jī)這一設(shè)備。至于，壓機(jī)的壓下量，則是看實(shí)際情況和以往經(jīng)驗(yàn)。同時(shí)，進(jìn)行壓的時(shí)候，也可以通過(guò)儀表來(lái)知道其壓下量和反彈量，這樣，自己好心中有數(shù)。冷拉方鋼其是冷拉型鋼中的一種。將會(huì)進(jìn)行冷拉方鋼的學(xué)習(xí)工作，主要是來(lái)掌握其相關(guān)知識(shí)內(nèi)容，這樣，也可以擴(kuò)充自己的專(zhuān)業(yè)知識(shí)，并在冷拉方鋼的使用上，獲得好的使用效果。其是指一種鍛造形狀為方形的冷拉鋼，冷拉方鋼其從專(zhuān)業(yè)角度來(lái)講是屬于冷拉鋼。而這一種方鋼的彎曲，可以通過(guò)再結(jié)晶退火來(lái)提高韌性，然后，用彎花機(jī)來(lái)進(jìn)行彎曲工作。之后，則是為再結(jié)晶退火消除加工硬化這一問(wèn)題，并同時(shí)，恢復(fù)材料的塑性和韌性。

Cold drawn square steel As for the reduction of the press, it depends on the actual situation and past experience. At the same time, when pressing, you can also know the amount of depression and rebound by the instrument, so that you have a good idea. Cold drawn square steel is one of the cold drawn sections. The learning work of cold drawn square steel will be carried out, mainly to master its related knowledge content. In this way, you can also expand your professional knowledge and obtain good results in the use of cold drawn square steel. It refers to a cold-drawn steel with a square forged shape, and cold-drawn square steel is from a professional perspective. It belongs to cold drawn steel. The bending of this kind of square steel can be improved by recrystallization annealing to improve the toughness. Then, the bending machine is used to perform the bending work. After that, the problem of work hardening is eliminated for recrystallization annealing, and at the same time, the plasticity and toughness of the material are restored.
