In the production process of alloy pipe, there will be cold rolling of steel pipe, hot rolling of steel pipe. What is the effect of cold rolling and hot rolling of this steel pipe on the steel pipe? What's the difference between them? Below let Xiaobian to explain these problems in detail for you.

The first is hot rolling, in the hot rolling, it is to divide the steel into small grains, so as to make the steel more compact, the microscopic microstructure defects in the steel can be synthesized well, so that the mechanical properties of the steel are more perfect, when the hot rolled steel is poured, it can form bubbles, cracks and loose, Of course, it can also be welded under high temperature and pressure.

The so-called cold rolling, it is under the general temperature of cold drawing, cold bending, cold drawing and many other cold processing procedures, and then the steel processing into different forms of steel pipe, in the cold rolling, can be quickly formed, and its output is also very high, can be deformed into the desired shape.

The difference between cold rolling and hot rolling is that in cold rolling forming, it can have local buckling, according to this feature, it can have a certain bearing capacity, but hot rolling does not have such characteristics. In the cold and hot rolling, the distribution of their cross sections is not the same, the cross section on the curved wall tube of the cold rolling is curved, and the hot rolling is thin film type. The torsion resistance of hot-rolled section steel is better than that of cold-rolled section steel pipe during torsion of hot-rolled and cold-rolled.
