The curtain of carbon emission reduction has been opened, how should the steel industry develop?

"Green water and green mountains are golden mountains and silver mountains." There is no irreconcilable contradiction between industrial development and the ecological environment. At present, the global spread of the new crown pneumonia epidemic has triggered a profound reflection on the relationship between man and nature. The global response to climate change requires greater action. China, which is turning to high-quality development, has once again stood up. China will increase its national independent contribution, adopt more powerful policies and measures, strive to reach the peak of carbon dioxide emissions by 2030, and strive to achieve "carbon neutrality" by 2060. , Reflects the actions and responsibilities of a responsible major country.

What are the points to pay attention to during the forging process?

Forgings for Pressure Vessels The main processing method of mechanical parts blanks is forging. Through forging, the specific shape of the parts can be obtained, and the internal structure of the metal product can even be improved. Forging technology is generally used in the production and processing of products with high bearing capacity and relatively high requirements. It can improve the mechanical and physical properties of the product. The future development of forging manufacturers is definitely related to quality. If you want to find an excellent forging manufacturer, this is also fundamental. Good quality forgings and a good service attitude are very

What are the specifications when forging forgings?

The key to formulating cooling specifications for hot forging steel  is cooling rate. The appropriate cooling rate should be determined according to the chemical composition of the forging material, the characteristics of the structure, the cross-sectional size of the forging, and the forging deformation. Generally speaking, forgings with a low degree of alloying, a small cross-section and a simpler shape can allow a fast cooling rate and can be cooled in air after forging; otherwise, they must be cooled slowly (ash cooling or furnace cooling) or separated Stage cooling.

What are the precautions during austempering?

The concept of austempering Austempering refers to the process of isothermalizing the quenched parts above the Ms point temperature and the temperature region above the "nose" of the C curve for a period of time to fully transform austenite into lower bainite, and then take out air-cooled heat treatment. It can be seen that austempering is carried out within a certain temperature range, so the structural stress and thermal stress are relatively small. Austempering is usually used for workpieces with complex shapes and strict requirements for deformation.

How to improve the overall production efficiency of the forging factory?

In recent years, with the increasing complexity of forging products in the forging market, the advantage of forging processing efficiency of forging plants has now become one of the decisive factors for forging plants to strive for the market advantage of forging products. Therefore, how to improve the forging processing efficiency of forgings is important for forging plants. The advantage in the market competition plays a key role, and it is a transformation problem faced by many forging manufacturers.

What are the differences and advantages of hot-rolled steel and cold-rolled steel?

Both hot rolling and cold rolling are processes for forming steel plates or profiles, and they have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually only used for the production of small-sized steel and sheet steel with precision dimensions.

What are the performance requirements of cold work die steel?

Cold work molds are molds used for pressure processing or other processing of materials at room temperature. It has a wide variety and complex structure. The mold is subjected to mechanical forces such as compression, stretching, bending, impact, and friction during use. The normal failure modes of cold work die mainly include wear, brittle fracture, bending, seizure, collapse, gnawing, softening, etc. Therefore, cold work die steel is required to have high deformation resistance, fracture resistance, and wear resistance after phase change heat treatment. Abilities such as damage resistance, fatigue resistance, and seizure resistance to ensure that the mold has a certain degree of durability.

The hardness testing method and instrument selection of mold steel

Die steel is the main material of the mold industry. According to the different service conditions, environment and state of the mold, the mold steel should have different characteristics. In industrial production, the service life of the mold and the precision, quality and appearance performance of the finished parts are related to the design technology and manufacturing accuracy of the mold, as well as the accuracy of the machine tool and the manufacturing operation. The correct selection of mold materials and the correct implementation of the heat treatment process It is also very important. According to the data, the early failure of the mold is about 10% caused by improper material selection and internal defects of the material, and about 49% caused by improper heat treatment.
