The production process of seamless steel pipe for high pressure boiler is more strict than that of A588 grade A HSLA steel plate ordinary steel pipe. In the process of using seamless steel pipe for high pressure boiler, oxidation and corrosion will occur under the action of high temperature flue gas and steam. Therefore, the requirements for the durability and anti-oxidation corrosion performance of seamless steel pipes for high-pressure boilers are higher, and has requirements for good structural stability.
In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product A588 grade A HSLA steel plate structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel A588 grade A HSLA steel plate supplier in the world.
The hot rolling method is to heat the A588 grade A HSLA steel plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A588 grade A HSLA steel plate rolling process is usually called semi-finished product production, also called blank production.
Vanadium is a weak deoxidizer. Adding vanadium into A588 grade A HSLA steel plate steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.
Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world.
