1、冷拉方鋼在一些基礎(chǔ)方面是否有相應(yīng)的參考標(biāo)準(zhǔn)?
1. Does cold drawn square steel have corresponding reference standards in some basic aspects?
冷拉方鋼在基礎(chǔ)方面是有相應(yīng)的參考標(biāo)準(zhǔn)的。而在具體的參考標(biāo)準(zhǔn)為GB 906-82這一個。并且,在該標(biāo)準(zhǔn)中,是對冷拉方鋼的外形、尺寸、重量及偏差等,進(jìn)行了明確規(guī)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、冷拉方鋼和冷拉圓鋼,哪一個接觸面的壓強大?
2. Which of the contact surfaces of cold-drawn square steel and cold-drawn round steel has a strong pressure?
冷拉方鋼和冷拉圓鋼這兩種冷拉型鋼,是有很多不同之處的。所以,它們是不一樣的,大家不要給混淆了。而從接觸面壓強這一具體方面來進(jìn)行比較的話,那么,是冷拉方鋼接觸面的壓強要大很多,所以,在這個問題上,其的答案,是為冷拉方鋼。
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、怎樣來提高冷拉方鋼的韌性?
3. How to improve the toughness of cold drawn square steel?
想要來提高冷拉方鋼的韌性,行之有效的措施是為再結(jié)晶退火,用來消除其加工硬化這一現(xiàn)象問題,并能提高冷拉方鋼的塑性和韌性。而且在操作上,也是非常簡單的,并不復(fù)雜。
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.
