1、冷拉圆钢与普通的圆钢进行比较的话，它的优点是什么？
1. What are the advantages of cold drawn round steel compared with ordinary round steel?
冷拉圆钢的材质是经过调质处理的，所以在性能上是有很大提升的。因此，与普通圆钢进行比较的话，冷拉圆钢是有一些优势的，比如，它可以直接用来当轴使用，不需要再进行加工了。而且，在表面光滑度和机械性能上，也是有很大提高的。这些是它的主要优势。
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、如何来判断圆钢是锻造、热轧还是冷拉的？
2. How to judge whether round steel is forged, hot rolled or cold drawn?
圆钢是锻造、热轧还是冷拉的？冷拉型钢生产厂家建鑫型钢认为，这是三种常用的加工方式，而且，都是有广泛应用的。它们之间的具体区别是在工艺方式上，以及其产品所对应的用途上。一般来讲，冷拉圆钢，其是在五金配件加工上，而热轧圆钢，还可以用于建筑中。
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、冷拉圆钢中可以用的牌号有哪些？以及其表示为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?
冷拉圆钢中可以用的牌号，据冷拉型钢生产厂家建鑫型钢介绍，主要是有普通碳素钢A3、25号和45号钢，这些是比较常见和常用的。如果冷拉圆钢表示是为11-20/45的话，那么，则说明了该圆钢直径的具体数值。
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.
