From the outside the steel ingots – known in the industry as steel billets – look like ordinary steel. But the delivery of these billets is a special first: the first delivery of lowcarbon steel from Saarstahl Ascoval, the new Saarstahl subsidiary in the north of France (Saint-Saulve), has arrived at the Burbach works. There they are rolled into wire and delivered to the first customers in the construction industry.
Dillinger is continuing its strategic partnership with the Materials Science and Engineering Department at Saarland University and the Steinbeis Research Center for Materials Science (MECS). With this Steel Development 4.0, Dillinger is promoting the university’s research into the microstructure of special steels and is bolstering its position as an innovation driver in heavy plate production.
SSAB will display its plan for fossil-free steelmaking at Expo 2020 in Dubai, as well as highlight the importance of fossil-free value chains as a solution to the climate crisis. A green transition is necessary to tackle climate change, it is also the best business plan, strengthens competitiveness and builds prosperity.
The bearings used in continuous casting machines have to endure arduous operating conditions that include high temperatures, heavy loads, ultra-low speeds, water/water vapour and scale. As a result, bearing failures such as wear, flaking and fracture are commonplace, prompting increasing numbers of steel manufacturing plants to adopt NSK SWR (Super Wear Resistant) spherical roller bearings. These advanced bearings provide several times more wear resistance, flaking life and outer ring toughness than standard counterparts made from AISI 52100 bearing steel.
Single-phase material bonding allows precise control of the composition
Tungsten alloys (WNiFe / WNiCu) are used because of their corrosion resistance against molten metal and high thermal conductivity for chill-mould casting processing of aluminium. Yet, also in tool manufacture and for shielding from alpha and gamma radiation, the heavy metal with its density comparable to gold is indispensable.
