早期，在人类知识最前沿的海事工程的一个例子。事实上，这个工程是如此先进以至于她极难航

行——这也是她下沉的一个因素之一。1961年打捞她在某种意义上也是一种工程上的成功。”

“目前，我们将Sandvik和它的极其先进的材料技术用在了该船上——因此在某种意义上这艘船的故

事一向都是与目前最先进的技术联系起来的。”

第一年合作将更换1000套螺栓，而且这些都是受到船的运行和内部压评估力的严密监控的。这些新

的螺栓是由7个不同零部件组装成的，主要的部件是28x2毫米的SAF 2707HD管子。

Peter Gossas评论道，“能够在帮助保护不可替代的国宝如Vasa中扮演一个重要的角色对我们来说

是一个特别的待遇。它展示了我们作为瑞典公司能提供的广泛的材料工程方面的专业知识。”

“很适合的是我们能够提供当今最先进的材料技术来帮助保护17世纪的创新的海洋技术。这是在向

这么多年来的瑞典技术致敬，并且能持续到未来数年，让所有人都能享受。”

巧合的是，宣告合作正是在Vasa 1961年4月在斯德哥尔摩港口驶向水面的50周年纪念之前。这一纪

念将从2011年4月开始整年庆祝。2012年，Sandvik也将庆祝其150周年纪念。

Modernisation at Volzhsky Trubny Zavod Production output doubled

THE Russian steelworks, Volzhsky Trubny Zavod (VTZ), has significantly strengthened its competi-

tiveness thanks to a major modernisation by SMS Meer, SMS Siemag and SMS Innse. The produc-

tion capacity of the works is now 630,000 tons of tubes per year, and hence twice the capacity prior

to the modernisation.

While SMS Siemag was replacing the four-strand continuous round caster in the steelworks, SMS

Meer and SMS Innse took care of the modification of the 16 ¾”-Multistand Pipe Mill (MPM). These

measures resulted i.a. in shorter cycle times of the rolling line and the use of higher billet weights,

and hence to a significant improvement in productivity.

The piercing process was changed over to a process with round instead of square billets. A crucial

advantage of this is the saving of a whole forming step and minimum eccentricities in the finished

product. Furthermore, modern transport facilities ensure that the rolled stock passes rapidly through

the mill. Tool wear is reduced, less problems occur during rolling – and all this has a positive impact

on the productivity.

With the new MPM process it is now possible to insert the mandrel bar in-line. This results in a

shorter contact time between shell and mandrel bar, and hence in a smaller temperature loss in the

rolled stock.

SMS Meer has also modernised the automation and measurement technology. Among other things

the team replaced the operator panels in the control rooms and upgraded the sensors. A new meas-

uring system records the diameter, wall thickness, length and temperature of the hot finished tube.

The wall thickness is measured online using the LASUS® (Laser-Ultrasonic) measuring system de-

veloped by SMS Meer. Integrated into a quality assurance system (QAS), this enables the product

quality to be monitored and the mill settings to be adapted.

With the measures undertaken, OAO Volzhsky Pipe Plant has been able to strengthen its leading

position among the tube manufacturers in Russia. The company now has the world’s most modern

MPM plant in this size range on the international market.
