In the process of hot rolled square steel making, for the control of the temperature must be strictly enforced, otherwise will lead to deformation, and is unable to control the deformation, the size of the products at the same time also can appear the phenomenon of instability, especially the influence of the dimensions of the cycle of very clear, so in order to be able to control all aspects of the finished product quality precision, in the production process must strictly control the good aspects of standard requirements.

Want to know if the product production is completed, the show is not have good performance, so there will be a problem in the later use, there may be some problems when see the finished product has, nature also cannot be directly applied to the actual situation, how wear also want to undertake the processing, see if can have the normal application of standards, and then to the application.

After all, we do not know where such products will be used in the future, but the manufacturer must be responsible for its quality, which is also responsible for themselves.If hot rolled square steel has rust, it can be dealt with in several ways, and this problem is relatively obvious.Generally speaking, there are two kinds of cases, one is in the production of polishing process, which needs to be in the rust after the polishing, there is also a has done bad polishing or there is no polishing, have to spray protection treatment.

In fact, like the steel surface of some oil, can be used to clean the metal cleaning powder, can also use stainless steel cleaning pulp.As for the surface of the product rust relatively light or less can be clear with stainless steel smooth water, and the rust is more serious words can be used to remove rust paste or rust water.
