What is the reason for steel rails wear resistance

The steel rails are formed after the scrap metal is smelted, and then rolled, processed, straightened, and sawn. Let's take a look at the key to the rail production process with Xiaobian!

Key to steel rails production process

1. The use of outside furnace refining and vacuum degassing technology to ensure the internal quality of the slab, control the residual elements and gas content in the steel, and ensure the purity of the steel.

2. Continuous casting of blooms is used to improve the low magnification structure of billets.

3. The walking billet is used to heat the billet, which can effectively control the atmosphere in the furnace and prevent the steel from decarburizing and uneven heating temperature during the heating process.

4, using high-pressure water descaling technology. It can minimize the occurrence of defects such as rolling marks caused by scale.

5. Universal rail hole design and computer are used to adjust the steel rails geometry on-line to ensure the rolling accuracy of rail section.
