With the continuous progress of social economy, various rails are widely concerned by the steel market, heavy rail is the focus of production in many enterprises, our company understands the basic production and maintenance technology for mastering heavy rail, the following are the basic production control techniques for heavy rail.

1.[O]and [H] content control technology

By increasing the alkalinity of high-melting slag, making white slag and reducing slag oxidation, continuous casting ensures steady casting and other measures to control the oxygen content of heavy rail steel; control the hydrogen content of heavy rail steel by taking high vacuum degassing, sufficient degassing time and appropriate driving argon flow rate, Guarantee [O] ? 20ppm of heavy rail steel; [H] ? 1.2ppm.

2.Inclusion control technology

The concentration of inclusions in the heavy rail is prone to stress concentration, which is the source of fatigue cracks. Control argon blowing by optimizing deoxidation, refining and vacuum treatment, adjust the temperature control range of the package, improve the alkalinity of the slag, and strengthen the work of whitening slag, measures to reduce slag oxidation, control the inclusion of Al2O3 in steel, control the class A inclusions of heavy rail steel below 1.5, B, C, D type inclusions are controlled below 1.0, requirements for the provisional technical conditions for passenger steel lines of 250km/h and 350km/h.

The company has more than 20 years of experience in the steel industry, the company operates and sells a variety of types of rail and rail accessories, such as fish plate, tie plate, and rail turnout. The company has formed a strong sales system during its operation. We can provide customers with secondary processing of steel rails such as steel rail punching and cutting, and more importantly, we can provide customers with high-quality products and competitive prices.
