近十年来钢管生产技术有很大的发展,本文拟从穿孔、轧管、精轧三个方面对热轧技术发展的现状及其发展趋势加以探讨。一、钢管热轧技术的发展趋势近年来,有一些新的无缝钢管厂投产,这些厂采用了各种不同的、异于经典的穿孔、轧管工艺,具有代表性的是表1所列的十个无缝钢管厂,这十个厂基本上代表了当前无缝钢管热轧技术发展的基本趋势。
In recent ten years, there has been a great development of steel pipe production technology. This paper intends to discuss the current situation and development trend of hot-rolled steel technology from three aspects of perforation, pipe rolling and finish rolling. First, the development trend of hot-rolled steel pipe technology In recent years, a number of new seamless steel pipe plant put into operation, these plants using a variety of different from the classic perforation, rolling process, representative is listed in Table 1 Of the ten seamless steel pipe plant, which ten plants basically represents the current trend of the development of hot-rolled seamless steel pipe technology.
