Source Manufacturer Cns Sncm220 Steel Hot Rolling Process - China

CNS SNCM220 steel is a medium-carbon alloy carburizing steel, and its hot rolling process is crucial to ensuring its performance.

The following are key points regarding the hot rolling process of SNCM220 steel: 1 - Heating Temperature: The initial rolling temperature is generally controlled between 1150-1200℃.

Within this temperature range, the steel exhibits good plasticity and low deformation resistance, facilitating rolling processing.

2 - Finishing Rolling Temperature: The finishing rolling temperature should not be lower than 850℃ to ensure the steel achieves good microstructure and properties during rolling.

If the finishing rolling temperature is too low, the steel's deformation resistance will increase, making it prone to defects such as cracks, and it will also affect the steel's mechanical properties.

3 - Rolling Speed: The selection of the rolling speed should be determined based on factors such as the steel specifications, equipment capacity, and process requirements.

Generally, appropriately increasing the rolling speed can improve production efficiency, but it is also necessary to carefully control the rolling rhythm to ensure the uniformity of steel temperature and deformation.

4 - Cooling Method: The cooling process after rolling also significantly impacts the microstructure and properties of CNS SNCM220 steel.

Air cooling is typically used, allowing the steel to cool naturally in the air.

This results in a more uniform microstructure and good overall mechanical properties.

In actual production, the hot rolling process needs to be optimized and adjusted according to specific production conditions and product requirements to ensure that the quality and properties of CNS SNCM220 steel meet the standard requirements.
