Please cite this article in press as: Bergquist, B. The ability to track and trace products in a production process and in the transportation chain from supplier to customers is important for quality control and process improvements. However, good traceability is often difficult achieve for continuous process products as well as for batch produced products where batches intermix. In this paper,...

Cryogenic scanning electron microscopy (cryo-SEM), image analysis (IA) of SEM micrographs and X-ray microtomography (XMT) were used to obtain new information about the morphology of iron ore green pellets in this work. Cryo-SEM and freeze fracturing was used to observe entrapped air bubbles and arrangement of particles around the bubbles and in the matrix of wet green pellets. The observations ...

Direct reduction of iron ore (DRI) is gaining an increased attention due to the growing need decarbonize industrial processes. The current DRI processes are performed using reformed natural gas, which results in CO 2 emission, although it less than carbothermic blast furnace. Carbon‐free may be realized through utilization green H as a reducing agent, place gas. Herein, effects various gas mixt...

Steel production is the most dynamic industry and one of key sectors for development global economy. The growing iron ore increases need its beneficiation granulating subsequent use in steel. As a result, number CO2 emissions harmful substances increases, which negatively affects both society environment. It important to study biomass pellets. Lignocellulosic renewable sustainable source heat e...
