About The Customer
Nemag BV is a manufacturer of grabs designed for handling a range of bulk materials from coal and iron ore to grain, animal feed, scrap metal, minerals, and biomass. They collaborated with the group of Dr. Dingena Schott at Delft University of Technology (TU Delft) to develop a new generation of grabs for iron ore that are faster and lighter. They used Altair EDEM™ bulk material simulation software to test and optimize the new design.
The Challenge
Nemag BV, a manufacturer of grabs for handling bulk materials, faced a challenge in developing a new generation of grabs for iron ore that were faster and lighter. The traditional process of developing grabs involved building physical prototypes, which was expensive, time-consuming, and limiting. It was difficult to predict the performance of a new design, especially the interaction between the bulk material and the grab, which heavily influences the performance. The traditional methods were not sufficient to understand what happens inside the grab. Therefore, a virtual prototyping approach was developed at TU Delft to model iron ore pellets in interaction with grabs.
The Solution
TU Delft used Altair EDEM™ bulk material simulation software to perform virtual testing of a grab design and predict its performance. They developed a coupling to use EDEM Discrete Element Method with multibody dynamics simulation software, which allowed them to model iron ore pellets and a crane in a virtual environment. Extensive model calibration procedures were developed to account for material structure interaction. This approach effectively captured both material behavior and grab behavior. The co-simulation was validated with measurements on an industrial scale at Tata Steel IJmuiden in the Netherlands. The coupled simulation was then used in the innovative design process, providing key insight into the dynamics of the grab together with the iron ore.

Continuous Casting Machines in a Steel Factory
With a very broad range of applications, steel is an important material and has been developed into the most extensive alloy in the engineering world. Since delivering high quality is absolutely crucial for steel plants, ensuring maximum productivity and the best quality production are the keys to competitiveness in the steel industry. Additionally, working conditions in steel factories are not suitable for workers to stay in for long periods of time, so manufactures usually adopt various machines to complete the steel production processes. However, the precision of these machines is often overestimated and the lack of flexibility also makes supervisors unable to adjust operating procedures. A renowned steel factory in Asia planned to improve its Distributed Control System (DCS) of furnaces as well as addressing the problem of insufficient accuracy. However, most well-known international equipment suppliers can not provide a satisfactory solution and local maintenance because the project needed new technologies to more accurately control equipment operations. By implementing Advantech’s automated monitoring and control solution, steel factories can not only improve the manufacturing processes but can also allow users to add additional functions to the existing system so as to make sure the operation runs at high efficiency.
