Basic situation analysis of hot-rolled structural pipes

Nowadays, there are many types of steel pipes, including hot and cold structural steel pipes. However, today we will talk about hot-rolled structural steel pipes. But for this type of structural tube, if you are not familiar with it, then you need to make a good choice to avoid any problems during use? That's even worse, specifically for hot-rolled structural pipes.

In fact, this hot-rolled structural tube uses continuous casting slabs or blooms as raw materials, which are heated by a walking beam heating furnace, and high-pressure water is used to remove phosphorus. After entering the roughing mill, the roughing material will be cut and tail, and then enter the finishing mill. The rolling process is mainly controlled by the computer. After the final rolling, it is cooled by laminar flow and coiled by the coiler, becoming a straight coil.

The head and tail of this straight curl usually exhibit tongue and fish tail shapes, with poor accuracy in thickness and width. There are often defects such as wave shaped, folded edges, and tower shaped edges.

If the coil weight is relatively heavy, the inner diameter of the steel coil is 760mm. After the straight coil is processed through head cutting, tail cutting, edge cutting, and multiple passes of straightening, leveling, and other finishing lines, it is cut or re rolled, that is, hot-rolled steel plates and other products. Generally, if the hot rolled finished coil is pickled, the oxide skin can be removed and coated with oil, which then becomes the hot rolled pickled plate coil. Of course, this also belongs to a type of hot-rolled structural pipe, and correct judgment must be made when selecting it.

The above is the basic information of Yuantai Derun Steel Pipe Group on hot-rolled structural pipes, which has been provided with a detailed understanding. When making your own choices, you can better choose the most suitable structural pipe to use. Only in practical use can it truly play its role in helping one's structural projects solve some problems.
