镀锌方管的工艺分类您知道吗?

发布时间:2021-05-13 来源:/

镀锌方管是一种在方管的基础上面,进行了合适的镀锌处理的管材,因此在应用范围方面有了比较好的提高,可以使用在机械制造和钢结构工程等领域,具有比较好的使用效果。那么您知道该产品的工艺分类和具体的区别吗?就先让济南镀锌方管的小编给您来简单讲解一下吧。

Galvanized square pipe is a kind of pipe with proper galvanizing treatment on the basis of square pipe, so it has a better improvement in the scope of application, and can be used in the fields of mechanical manufacturing and steel structure engineering, with better use effect. Do you know the process classification and specific difference of this product? Let's first let Jinan galvanized square tube's editor give you a brief explanation.

镀锌方管从生产工艺上是分为热镀锌方管和冷镀锌方管的。正是由于这两种镀锌方管的加工不相同也就造就了它们很多不同的物理和化学性质。总的来说它们在强度、韧性和机械性能方面有很多的区别。

Galvanized square tube is divided into hot-dip galvanized square tube and cold-dip galvanized square tube from the production process. It is because of the different processing of these two kinds of galvanized square tubes that they have many different physical and chemical properties. Generally speaking, they have many differences in strength, toughness and mechanical properties.

1.热镀锌方管:

1. Hot dip galvanized square pipe:

是在使用钢板或者是钢带卷曲成型后焊接制成的方管,并在这种方管的基础上将方管置于热镀锌池中经过一系列化学反应后又形成的一种方管。热镀锌方管的生产工艺较为简单,且生产效率是高的,品种规格也多,这种方管所需要的设备和资金少,适合小型镀锌方管厂家的生产。但是从强度上来说这种钢管的强度是低于无缝方管的。

It is a kind of square tube which is made by welding after rolling steel plate or steel strip. On the basis of this kind of square tube, the square tube is put in the hot-dip galvanizing bath and formed after a series of chemical reactions. The production process of hot-dip galvanized square tube is relatively simple, and the production efficiency is high, and there are many varieties and specifications. This kind of square tube needs less equipment and capital, which is suitable for the production of small galvanized square tube manufacturers. But in terms of strength, the strength of this kind of steel pipe is lower than that of seamless square pipe.

2.冷镀锌方管:

2. Cold galvanized square pipe:

而冷镀锌方管是在所用的方管上利用冷镀锌的原理来使方管具有防腐蚀的性能。与热镀锌不同冷镀锌涂料主要通过电化学原理来进行防腐,因此须使得锌粉与钢材的接触,产生电极电位差,所以钢材表面处理很重要。

The cold galvanizing square tube is to use the principle of cold galvanizing to make the square tube have anti-corrosion performance. Different from hot-dip galvanizing, cold-dip galvanizing coating mainly uses electrochemical principle for anti-corrosion, so it is necessary to make the contact between zinc powder and steel, resulting in electrode potential difference, so steel surface treatment is very important.

3.冷热镀锌区别:

3. Difference between cold and hot galvanizing:

镀锌方管有热镀锌方管和电镀锌方管两类。热镀锌方管有湿法、干法、铅锌法、氧化还原法等。不同热镀锌方法的主要区别在钢管酸浸清洗后,用什么方法活化管体表面提高镀锌质量。现生产中主要采用干法和氧化还原法。电镀锌的锌层表面光滑致密、组织均匀;具有良好的力学性能和抗腐蚀能力;锌耗比热镀锌低60%~75%。电镀锌在技术上有较多的复杂性,但对单面镀层,内外表面镀层厚度不同的双面镀层,以及薄壁管镀锌等须采用此法。

There are two kinds of galvanized square tubes: hot-dip galvanized square tube and electro galvanized square tube. Hot dip galvanized square tube has wet, dry, lead-zinc, oxidation-reduction method. The main difference of different hot-dip galvanizing methods lies in how to activate the surface of steel tube after acid leaching to improve the quality of galvanizing. At present, dry process and oxidation-reduction process are mainly used in production. The surface of zinc coating is smooth, compact and uniform; It has good mechanical properties and corrosion resistance; Zinc consumption is 60% ~ 75% lower than that of hot dip galvanizing. There are many technical complexities in galvanizing, but this method must be used for single-sided coating, double-sided coating with different thickness of inner and outer surface coating, and thin-walled tube galvanizing.
