热拉钢丝与冷拉钢丝的区别：
The difference between hot-drawn steel wire and cold-drawn steel wire:
热拉就是加热之后拉丝亦或者边加热边拉丝，目的就是为了让线材在高温的情况下柔韧性以及拉伸性得到增强。通俗点讲就是让不易拉伸的材料或者尺寸变得比较容易拉伸。

Hot drawing is drawing after heating or while heating, in order to make the wire more flexible and lvhuamiao.37ix.com.cn jidi.37ix.com.cnguohuai.37ix.com.cnnijiangbeng.37ix.com.cnzhajiangb.37ix.com.cnzhangjiak.37ix.com.cn

stretchable at high temperature. Popular point is to make materials or sizes that are not easy to stretch easier.

冷拉就是现在市场上普遍的一种金属线材加工方式，无须加热，用拉丝液作为润滑和保护的液体，对线材进行强制性拉伸和冷成型，这种方式会改变晶体的结构。
Cold drawing is a common processing method of metal wires on the market. It does not need heating. It uses drawing fluid as lubricating and protective liquid to force drawing and cold forming of wires. This way will change the crystal structure.
