Hardox 450 (ハルドックス450) を使ったコンクリートミキサーのドラムなら、従来6回の積み込みが必要だったところ、5回に

コンクリートミキサーのドラムは、硬く湿ったコンクリートに連続的に曝される過酷な環境で作動し、激しく摩耗します。さらに、重量物運搬車に対する最大重量の規制が世界的に厳しくなっており、新たな課題を生み出しています。

コンクリートミキサー車は、極めて頑丈で、同時にとても軽くなくてはならないのです。車体重量が軽いほど、積載重量を増やせるので生産性が向上し、一方で燃料消費量を抑え、環境への影響も少なくなります。

SSABの高強度鋼を使用すれば、構造物を著しく軽くできます。市場の厳しい要件に適合できる鋼板として、SSABの耐摩耗鋼板Hardox 450があります。

Hardox 450 in Concrete Mixer Drums Enables a Saving of One in Six Loads

PR60989

SINGAPORE, June 29, 2015 /PRN=KYODO JBN/ --

   Concrete mixer drums operate in a very tough environment with hard and wet

concrete that continuously exposes the drums to extreme wear. Also, increasing

regulations on the maximum weight of heavy goods vehicles around the world

creates challenges.

   Besides being very tough, concrete mixer trucks must also be very light.

Lower tare weight enables higher payloads, increasing productivity while

reducing fuel consumption and environmental impact.

   SSAB's high-strength steels make it possible to build significantly lighter

applications. One steel  that meets demanding market requirements is SSAB's

wear-resistant steel, Hardox 450.

   In recent years SSAB has made significant developments when it comes to thin

Hardox. New, pioneering quenching technics introduced in the strip mill are

especially favorable for producing thin wear resistant steels. "A good

combination of bending properties and through-thickness hardness together with

excellent surfaces characterize thin Hardox," says Joachim Larsson, head of

Product Development.

   A concrete mixer drum made of Hardox 450 can be made very light without

compromising on service life and gives the customer a:

   - durable mixer drum with good resistance to wear and denting

   - significantly lighter mixer drum

   - possibility to increase payload, which in many cases enables a saving of

     one in six loads

   Finding: Up to 50% weight reduction possible with Hardox 450

   Studies have shown that it is possible to manufacture an extremely light and

strong concrete mixer drum in Hardox 450 without reducing service life. The

conceptual model was built using 3mm Hardox 450 in both the shell of the drum

and the spirals, resulting in up to 50% weight reduction compared to

conventional mixer drums. This reduction in weight means higher payloads, lower

fuel consumption and less environmental impact.

   Comprehensive offering for concrete segment

   In addition to Hardox 450 wear-resistant steel for concrete mixer drums,

SSAB can offer a wide range of other solutions to combat the challenges of the

industry. Strenx 700 MPa high-strength structural steel enables the design of a

lighter structure for the pedestal and subframe. Hardox 500 Tubes have been

tested in the field with excellent results. A concrete pumping tube is an

excellent case example of an application where tube needs to resist extreme

internal and external wear.
