3. Mechanical properties and production process of plates, round bars, forgings, seamless pipes and other products
The mechanical properties of the material vary depending on the production method and the environment in which it is used, but it exhibits good strength and toughness under general conditions. Plates, round bars, forgings, seamless pipes and other products are the main application forms of this material, and the following are the production processes of these products:
1.Sheet production:It is produced by cold or hot rolling. When cold rolling, it is necessary to pay attention to controlling the rolling temperature to ensure the performance of the material.
2.Round bar production:It is usually produced by continuous casting round billets. After hot rolling or forging, the required specifications can be obtained.
3.Forging production:It is produced by forging process, which can obtain excellent mechanical properties and excellent shape.
4.Seamless Tube Production:It is produced by continuous casting billet or round billet through perforation and other processes. Attention should be paid to controlling temperature and deformation during the production process to ensure the quality and performance of the product.
Fourth, electroslag and electric furnace smelting process
The smelting process of 06Cr19Ni13Mo3 usually adopts electroslag and electric furnace processes. Both processes can effectively remove impurities from the material and improve the purity of the material. The electroslag smelting process has the advantages of fast melting speed, pure metal and low electrode consumption, which is especially suitable for smelting alloy steels such as high-grade stainless steel. The electric furnace process can flexibly adjust production according to market demand and improve production efficiency.
5. The difference between casting and forging
Casting and forging are two different metal forming processes, and the difference between casting and forging of 06cr19ni13mo3 is mainly manifested in the following aspects:
1.Casting 06cr19ni13mo3 is a process of melting metal materials, and the shape of the parts produced by this process is usually relatively simple and cannot be deformed largely.
2.Forging 06cr19ni13mo3 is to improve the mechanical properties of the material by putting the metal blank into the mold and changing its shape by applying pressure. The shape of the parts produced by this process can be more complex and can be deformed largely.
6. Problems and solutions encountered in use
During use, 06Cr19Ni13Mo3 may encounter problems such as corrosion, deformation, and cracking. These problems can be solved by optimizing the use environment, regular maintenance, replacing materials, etc.
