1、冷拉圓鋼與普通的圓鋼進(jìn)行比較的話，它的優(yōu)點是什么？

1. What are the advantages of cold drawn round steel compared with ordinary round steel?

冷拉圓鋼的材質(zhì)是經(jīng)過調(diào)質(zhì)處理的，所以在性能上是有很大提升的。因此，與普通圓鋼進(jìn)行比較的話，冷拉圓鋼是有一些優(yōu)勢的，比如，它可以直接用來當(dāng)軸使用，不需要再進(jìn)行加工了。而且，在表面光滑度和機(jī)械性能上，也是有很大提高的。這些是它的主要優(yōu)勢。

The material of cold-drawn round steel is quenched and tempered, so the performance is greatly improved. Therefore, compared with ordinary round steel, cold-drawn round steel has some advantages. For example, it can be used directly as a shaft without further processing. In addition, the surface smoothness and mechanical properties have also been greatly improved. These are its main advantages.

2、如何來判斷圓鋼是鍛造、熱軋還是冷拉的？

2. How to judge whether round steel is forged, hot rolled or cold drawn?

圓鋼是鍛造、熱軋還是冷拉的？冷拉型鋼生產(chǎn)廠家建鑫型鋼認(rèn)為，這是三種常用的加工方式，而且，都是有廣泛應(yīng)用的。它們之間的具體區(qū)別是在工藝方式上，以及其產(chǎn)品所對應(yīng)的用途上。一般來講，冷拉圓鋼，其是在五金配件加工上，而熱軋圓鋼，還可以用于建筑中。

Are round bars forged, hot rolled or cold drawn? Cold-drawn section steel manufacturer Jianxin Section Steel believes that these are three commonly used processing methods, and they are widely used. The specific difference between them is in the process method and the corresponding use of their products. Generally speaking, cold-drawn round steel is used in the processing of hardware accessories, while hot-rolled round steel can also be used in construction.

3、冷拉圓鋼中可以用的牌號有哪些？以及其表示為11-20/45，是代表什么？

3. What are the grades that can be used in cold drawn round steel? And what is represented by 11-20 / 45?

冷拉圓鋼中可以用的牌號，據(jù)冷拉型鋼生產(chǎn)廠家建鑫型鋼介紹，主要是有普通碳素鋼A3、25號和45號鋼，這些是比較常見和常用的。如果冷拉圓鋼表示是為11-20/45的話，那么，則說明了該圓鋼直徑的具體數(shù)值。

The grades that can be used in cold-drawn round steel, according to the cold-drawn section steel manufacturer Jianxin section steel, mainly include ordinary carbon steel A3, 25 and 45, these are more common and commonly used. If the cold drawn round steel is 11-20 / 45, then the specific value of the diameter of the round steel is explained.
