Recently, Primetals Technologies received the Final Acceptance Certificate (FAC) for the modernized rolling mill for long products at JSW Steel Ltd. in Salem, India. The core of the modernization project was the new reversing roughing group with Red Ring stands, which enables to increase the size of the blooms to be processed to 220 mm.
NSK’s expertise in solving issues for the worldwide steel industry is helping achieve savings of €372,555 per annum on a continuous annealing line thanks to the elimination of unplanned downtime resulting from failed bearings.
In late October, Chinese steel producer Beihai Chengde Stainless Steel Co. (Beihai Chengde) achieved their full reduction program on their new Power X-HI 3-stand mill on HRAPL#5, exceeding 60 % reduction on 304 grades with white coil process, 55 % on series 200 black coil process.
On 25 November 2019, Dung Quat Blast Furnace #2 was successfully blown-in by Hoa Phat Steel, Vietnam. This is the second of four greenfield Danieli Corus Blast Furnaces that are being built under a single contract signed in Summer of 2017. Blast Furnace #1 was blown-in on 29 June 2019 – within 24 months after contract signature.
If the weight of PCD tools is reduced, as a rule significantly higher cutting data can be used. Along with design freedom, the possibility of weight optimisation is one of the crucial advantages offered by 3D printing. Due to the specially developed structures inside the tool, which cannot be manufactured conventionally, the weight can be reduced significantly.
After experiencing ongoing problems with the bearings on a vital milling machine at a steel plant, the management team turned to NSK for a solution. This decision proved to be extremely lucrative, with the steel mill now enjoying annual savings of €35,600.
Jindal Stainless Ltd. issued the final acceptance certificate for the new level-2-process automation on AOD converter #1 to Primetals Technologies in April 2019. The AOD converter was equipped with a level-1-system and brought into operation by a third party in 2010.
Additive manufacturing, which is much better known to most people as 3D printing, has been in use in plastics engineering for many years. However, the method offers potential for many further applications: architecture, design, medical engineering, packaging or mechanical engineering. The services offered by Würth Industrie Service GmbH & Co. KG are specifically geared towards machinery and plant engineering. Thanks to these services, initial samples, prototypes, certified serial parts, spare parts and tools come from a single source from batch size one — a quick and cost-efficient supply process, not just for C-Parts.
SSAB starts a study in Finland for fossil-free steelmaking. In line with the HYBRIT project, SSAB is taking the next step for a completely fossil-free steel value chain. In partnership with Gasum, Neste and St1, SSAB is initiating an Energy4HYBRIT prefeasibility study supported by Business Finland to investigate the use of fossil-free energy sources, primarily biomaterial side-streams, to replace fossil fuels in certain steelmaking processes, for example rolling processes. The Raahe mill will act as SSAB’s pilot.
