Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following sa573gr.70 steel equivalent basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.
Chromium element (Cr element) can improve the strength and hardness of sa573gr.70 steel equivalent, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
