The direction of the seamless steel tube structure adjustment

China's current energy efficiency 10% lower than the international advanced level, the eight energy-intensive industry products unit energy consumption more, on average, 40% higher than the international advanced level, the steel industry carbon emissions by 12% of the total emissions, more than twice as tall as the world average. In varieties of hot-rolled steel, seamless steel tube rolling process energy consumption in the first place.

Why hot rolled seamless steel tube rolling process energy consumption value is bigger than other varieties of steel rolling energy consumption values?
Because in the rolling process of seamless steel tube, first after perforation, billet heating heating again after sizing, there are two heating process, failing to realize continuous casting and rolling, rolling work is bound to cause the complex process
In the future,the ERW steel pipes will replace the seamless steel pipes as ERW pipes are more low carbon industry and save more energy.
