在建筑工程施工現場經常用到的材料之一就是小口徑方矩鋼管，它的應用范圍非常廣，比如像建筑物的腳手架、模板支撐等等地方都會用到這種材料。那么今天我們就來了解一下小口徑的
濟南方管可用作煉鋼吹氧用管的內容吧。
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.
小口徑方矩管是一種空心截面、周邊沒有接縫的長條鋼材，因其具有中空截面，所以也叫它"面包管"。其規(guī)格以邊長為50mm的方形和邊長100mm的矩形為主。
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.
小口徑方管用作煉鋼吹氧用管，冶煉吹氧用鋼管一般用焊接鋼管，規(guī)格由3/8寸-2寸八種。用或Q195-Q235鋼帶制成。為防蝕，有的進行滲鋁處理。
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系列產品基礎上研制而成，結合了當前電弧爐煉鋼的實際需要，耐火度高、消耗量少、操作方便等特點。電弧爐煉鋼中輸送氧氣或其它氣體，在電弧爐內熔化并精煉鋼鐵。
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.
小口徑方管冶煉吹氧用鋼管按焊接方法不同可分為電弧方管、高頻或低頻電阻方管。電焊鋼管用于石油鉆采和機械制造業(yè)等，可用作水煤氣管等，大口徑直縫方管用于高壓油氣輸送。
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.
廠家生產的擴口，強度一般比直縫方管高，能用較窄的坯料生產管徑較大的方管，還可以用同樣寬度的坯料生產管徑不同的方管。
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.
但是與相同長度的直縫管相比，焊縫長度增加30~100%，而且生產速度較低。因此，較小口徑的方管大都采用小口徑方管，大口徑方管則大多采用螺旋焊。
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.
The small diameter square tube can be used as the tube for steelmaking and oxygen blowing as described above. I hope to give you some help. Please come to our website for more related matters http://www.yetechina.com Consult and understand!
