在建筑工程施工现场经常用到的材料之一就是小口径方矩钢管，它的应用范围非常广，比如像建筑物的脚手架、模板支撑等等地方都会用到这种材料。那么今天我们就来了解一下小口径的济南方管可用作炼钢吹氧用管的内容吧。

One of the materials often used in the construction site of construction projects is small diameter square steel pipe, which has a very wide range of applications, such as scaffolding, formwork support and other places. Today, let's learn about the small caliber Jinan square tube that can be used as a pipe for steelmaking and oxygen blowing.

小口径方矩管是一种空心截面、周边没有接缝的长条钢材，因其具有中空截面，所以也叫它"面包管"。其规格以边长为50mm的方形和边长100mm的矩形为主。

Small diameter square tube is a kind of long steel with hollow section and no seams around. It is also called "bread tube" because of its hollow section. The specification is mainly a square with a side length of 50mm and a rectangle with a side length of 100mm.

小口径方管用作炼钢吹氧用管，冶炼吹氧用钢管一般用焊接钢管，规格由3/8寸-2寸八种。用或Q195-Q235钢带制成。为防蚀，有的进行渗铝处理。

The small diameter square pipe is used as the pipe for steelmaking and oxygen blowing, and the steel pipe for smelting and oxygen blowing is generally welded steel pipe with 8 specifications ranging from 3/8 inch to 2 inch. It is made of or Q195-Q235 steel strip. In order to prevent corrosion, some are aluminized.

是在S系列产品基础上研制而成，结合了当前电弧炉炼钢的实际需要，耐火度高、消耗量少、操作方便等特点。电弧炉炼钢中输送氧气或其它气体，在电弧炉内熔化并精炼钢铁。

It is developed on the basis of S series products and combines the actual needs of current electric arc furnace steelmaking. It is characterized by high refractoriness, low consumption and convenient operation. In electric arc furnace steelmaking, oxygen or other gases are transported, and steel is melted and refined in the electric arc furnace.

小口径方管冶炼吹氧用钢管按焊接方法不同可分为电弧方管、高频或低频电阻方管。电焊钢管用于石油钻采和机械制造业等，可用作水煤气管等，大口径直缝方管用于高压油气输送。

According to different welding methods, steel pipes for smelting oxygen blowing with small diameter square tubes can be divided into arc square tubes, high-frequency or low-frequency resistance square tubes. Electric welded steel pipe is used for oil drilling and production and machinery manufacturing, and can be used as water gas pipe, etc. Large diameter straight seam square pipe is used for high-pressure oil and gas transmission.

厂家生产的扩口，强度一般比直缝方管高，能用较窄的坯料生产管径较大的方管，还可以用同样宽度的坯料生产管径不同的方管。

The strength of flares produced by manufacturers is generally higher than that of straight seam square tubes. Narrow billets can be used to produce square tubes with larger diameters, and billets with the same width can also be used to produce square tubes with different diameters.

但是与相同长度的直缝管相比，焊缝长度增加30~100%，而且生产速度较低。因此，较小口径的方管大都采用小口径方管，大口径方管则大多采用螺旋焊。

However, compared with the straight seam pipe with the same length, the weld length increases by 30~100%, and the production speed is low. Therefore, small diameter square tubes are mostly used for small diameter square tubes, and spiral welding is mostly used for large diameter square tubes.
