冷拉方鋼是在校直時會使用到壓機這一設備。至于，壓機的壓下量，則是看實際情況和以往經(jīng)驗。同時，進行壓的時候，也可以通過儀表來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。將會進行冷拉方鋼的學習工作，主要是來掌握其相關知識內(nèi)容，這樣，也可以擴充自己的專業(yè)知識，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，冷拉方鋼其從專業(yè)角度來講是屬于冷拉鋼。而這一種方鋼的彎曲，可以通過再結晶退火來提高韌性，然后，用彎花機來進行彎曲工作。之后，則是為再結晶退火消除加工硬化這一問題，并同時，恢復材料的塑性和韌性。

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.
