1、冷拉方钢在一些基础方面是否有相应的参考标准？
1. Does cold drawn square steel have corresponding reference standards in some basic aspects?
冷拉方钢在基础方面是有相应的参考标准的。而在具体的参考标准为GB 906-82这一个。并且，在该标准中，是对冷拉方钢的外形、尺寸、重量及偏差等，进行了明确规定。
Cold drawn square steel has corresponding reference standards in terms of foundation. The specific reference standard is GB 906-82. In addition, in this standard, the outer shape, size, weight, and deviation of cold drawn square steel are specified.
2、冷拉方钢和冷拉圆钢，哪一个接触面的压强大？
2. Which of the contact surfaces of cold-drawn square steel and cold-drawn round steel has a strong pressure?
冷拉方钢和冷拉圆钢这两种冷拉型钢，是有很多不同之处的。所以，它们是不一样的，大家不要给混淆了。而从接触面压强这一具体方面来进行比较的话，那么，是冷拉方钢接触面的压强要大很多，所以，在这个问题上，其的答案，是为冷拉方钢。
There are many differences between cold drawn square steel and cold drawn round steel. Therefore, they are not the same. Don't confuse them. If the comparison is made from the specific aspect of the contact surface pressure, then the pressure of the cold drawn square steel contact surface is much higher, so the answer to this question is cold drawn square steel.
3、怎样来提高冷拉方钢的韧性？
3. How to improve the toughness of cold drawn square steel?
想要来提高冷拉方钢的韧性，行之有效的措施是为再结晶退火，用来消除其加工硬化这一现象问题，并能提高冷拉方钢的塑性和韧性。而且在操作上，也是非常简单的，并不复杂。
Want to improve the toughness of cold drawn square steel, effective measures are annealing for recrystallization, used to eliminate the problem of work hardening, and can improve the plasticity and toughness of cold drawn square steel. In addition, the operation is very simple and not complicated.
