Influence of surface grinding quality control on surface quality of round steel2020-12-16GCR15 flush in the process of rolling round steel roller set by force is crucial, because the work roll roll surface glued aluminum layer too thick, too thin is harmful, serious when can cause equipment accidents and degradation products in flush roller w- The difference between Q345B round steel and other rebar2020-12-16Round steel is divided into hot rolling, forging and cold drawing.Q345B hot rolled round steel is 5.5-250 mm in size.Among them: 5.5-25 mm small round steel mostly in straight strips into bundles supply, commonly used for reinforcement, bolts and various
- How to deal with the surface rust of hot rolled square steel!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 phe
- Why does hot rolled square steel appear brittle fractureWhen the temperature is lower than a certain temperature value, hot-rolled square steel will change into a brittle state, and its impact absorption energy will decrease significantly. This phenomenon is called cold brittleness. In the process of low stres
- Cold drawn flat steel whether there is another name and its selection basisThis, cold-drawn flat steel manufacturers wuxi xing teng believes that although the two kinds of flat steel is conducted under the normal temperature state, but on the process of being used, or is there a big difference, because the former is for rolling,
