冷拉方钢是在校直时会使用到压机这一设备。至于，压机的压下量，则是看实际情况和以往经验。同时，进行压的时候，也可以通过仪表来知道其压下量和反弹量，这样，自己好心中有数。冷拉方钢其是冷拉型钢中的一种。将会进行冷拉方钢的学习工作，主要是来掌握其相关知识内容，这样，也可以扩充自己的专业知识，并在冷拉方钢的使用上，获得好的使用效果。其是指一种锻造形状为方形的冷拉钢，冷拉方钢其从专业角度来讲是属于冷拉钢。而这一种方钢的弯曲，可以通过再结晶退火来提高韧性，然后，用弯花机来进行弯曲工作。之后，则是为再结晶退火消除加工硬化这一问题，并同时，恢复材料的塑性和韧性。
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.
