SSAB Presents Innovation and Expertise
At CONEXPO-CON/AGG, SSAB presented innovative applications of high strength steel and wear plate. Exhibits included an Arc Design dumper body (Hardox wear plate), a lightweight truck trailer/chassis model (Domex high strength steel), and a Hardox Wearparts display showcasing wear parts for the construction, aggregates and yellow goods industries.
Lighter, stronger dumper bodies
Volvo Trucks is currently testing the Arc Design on its new Volvo FMX truck, built for heavy construction activities. As part of the testing process, Volvo Trucks is providing customers with Arc Design prototypes in various Russian regions for two-week trials. So far customer feedback on performance has been very positive, with Volvo hoping to achieve its target of increasing dumper body payload by 500 kg. As an added bonus, Arc Design also allows hot engine exhaust to be passed through the space below the convex floor to prevent materials adhering.
Lower cost and weight
The design is based on the idea that trailer construction should take full advantage of the properties of high-strength structural steel to offer significantly improved performance. SSAB engineers have built a trailer without a conventional frame. Instead, they focused on optimizing the benefits offered by Domex 960 – SSAB's 4 mm hot-rolled high-strength structural steel – by designing a self-supporting monocoque chassis. The new chassis consists basically of two halves. Plates are laser cut before bending. Longitudinal profiles can be used at the top and bottom of the trailer to handle forces resulting, for example, from tipping a trailer full of gravel.
In addition to clear benefits for users, the design also reduces production time and cost: There are only two longitudinal joints, which means greatly reduced welding work and far fewer components while facilitating the economical use of using robotic welding and laser hybrid welding.
Finding the optimum Hardox for the job
The erosion model is based on published research as well as on SSAB research with aggregate and large rocks. At macro level, WearCalc 2.0 predicts whether makeup of the abrasive materials will cause edges to penetrate the steel surface or to break. At micro level, the model uses mineral hardness to calculate erosion on different types of wear plate.
Optimized welding at your fingertips
The user enters the desired mechanical properties, welding process and plate materials involved. The software calculates a tolerance envelope showing the permissible heat input, and both working and interpass temperatures.
