Ningbo Powerway Alloy Material, subsidiary of Ningbo Powerway Group, has contracted Amova, a company of SMS group, to supply a logistics system for the complete works complex at its Yinzhou site in China. Ningbo Powerway Group is an important producer of non-ferrous metals bars, wire rod and strips in the Chinese economic region. The finished products made from these primary materials are used for a wide range of applications in the electrical and electronic industry.

Amova designs a complete, all-encompassing logistics concept for the facilities in Yinzhou with the intention to assure maximum efficiency of the material flow. Amova is going to link all process stages from the raw material storage area down to the dispatch area, including the higher-level materials control and tracking systems. The containers, which are manually filled in the raw material storage area with scrap blends for the different copper alloys, will be transported to the melt shop by means of rail-bound vehicles. There the containers will be stacked for intermediate storage until they are taken to the melting furnace by crane. Operation of the crane will be fully automatic, including the emptying of the containers.
Downstream of the melting and milling shop, the strips are intermediately stored in the flat product storage area which will be served by an automatic gantry-type crane. Freely navigating vehicles will transport the strips from there to and between the downstream processing stages – rolling, annealing, cleaning, cutting and slitting – and finally to the buffer store from whether they are taken to the packaging area. The packaged finished products will be intermediately stored in an automated high-bay store until they are dispatched.
Optimized plant logistics
Amova is also going to supply two transfer cars, each designed to autonomously pick up or put down three
containers at a time and transport the three containers as a set from the filling area to the intermediate storage area of the meltshop. The supply scope additionally includes a fleet of six freely navigating vehicles for the transport of the coils and the scrap containers, two additional buffer storage areas equipped with automatic cranes, a coil stacking device for the annealing plant, and the automated high-bay store, which – depending on the type of stored items − can accommodate up to 2,064 pallets. Also the management software for the various storage areas, including an integrated material flow control system, is part of the supply.
Last but not least, Amova will be responsible for the implementation of the Level 1 and Level 2 automation. The WMS (Warehouse Management System) will be set up as a redundant server system with virtualization. Until the MES (Manufacturing Execution System) will have been commissioned, the input terminals of the WMS will be used for the exchange of information with the various processing and cutting lines, and with other important constituents of the production process (e.g. the storage and buffer areas, and the Vehicle Management System of the freely navigating cars). In addition to acquiring process and material data, the WMS performs functions such as material tracking and plant performance analyses, which may be used as a basis for the independent calculation of Overall Equipment Effectiveness (OEE). The use of customized and animated graphics will make the system user-friendly, as a matter of course, also via mobile devices.
Commissioning of the entire works logistics is scheduled to be completed by early 2020. (Amova)
Primetals: Desulfurization and dedusting system comissioned
Recently, at the production site of Brazilian steel producer ArcelorMittal Monlevade a 130-ton-hot-metal desulfurization station (DeS) and a new dedusting system supplied by Primetals Technologies commenced operation. The desulfurization station represents the first installation of Primetals Technologies combining a volumetric dosing device for Magnesium (Mg) and a pressure dispenser for Calcium Oxide (CaO). Low sulfur levels of lesser than 0,005% (50ppm) can be achieved, Primetals states. The consumption of desulfurization agents is significant reduced and processing times are reduced to less than 30 minutes compared to treatment in a torpedo car. The associated level 2 system supplied by Primetals predicts the end sulfur content with high accuracy, deviations of real from predicted value is below 5ppm on average. The dedusting system installed in the melt shop processes approximately 900,000 m3/h. A handling system for 130-t-hot-metals ladles was also part of the project. The new equipment is part of an expansion and quality improvement program at ArcelorMittal Monlevade.

For the desulfurization station, Primetals was responsible for the engineering, supply and advisory services for reaction and start-up. Equipment encompassed a volumetric dosing device for dosing of Mg, a pressure dispenser for dosing CaO, lance and injection systems, the material handling system, including an unloading station, silos for storage, and material transport. An important part of the project is the complete level 1 and level 2 automation system with process models, enabling precise process control and dosing as well as reliable prediction of end sulfur content. This allows for flexible and optimum injection ratios of CaO/Mg from 2:1 to 10:1. The co-injection takes places with fully decoupled control of the conveying of Mg and CaO. The DeS station is designed to operate with fluidized CaO or CaC2 (Calcium Carbide) as well. Pure Mono-injection of CaO or CaC2 is possible, too.
The volumetric dosing device has two collateral pistons for the continuous and precise injection of Mg. The Mg flow rate is determined by the piston speed only and does not depend on the pressure in the system – there is no interaction with the pressure dispenser. With this mechanical system, the conveying rate of Mg can vary in a wide range of 3 to 15 kg/min. Powder materials like lime and calcium carbide are injected via the high performance pressure dispenser. All installed valves and control devices are designed for highest safety standard.
The new desulfurization station from Primetals replaced an existing desulfurization preformed in torpedo cars, reducing both the consumption of desulfurization agents and processing times. In addition, the effort for cleaning of torpedo cars is also lowered, deslagging simplified and metal losses during deslagging reduced.
New dedusting system covers two BOF converters, the DeS and slag skimming stand as well as the HM mixer. Primetals engineered, supplied and installed charging coolers for BOF charging evacuation, pulse jet filters with eight chambers and a filter area of 11,270 m2, and two induced draft (ID) fans with a power rating of 1,500 kW each. The filtered dust is discharged to containers. A handling system for the 130-t-hot metal ladles completed the scope of supply, including ladles, a transfer car with integrated ladle tilting device and a deslagging machine. (Primetals)

Since 2011, thyssenkrupp Steel has invested a total of around EUR 100 milion in a fabric filter project at its Duisburg site to clean the air from the sinter plant. The last of three fabric filters is scheduled to go into operation in spring 2020. In the course of the project another section of the filter has now been moved into position: with a weight of 17 tons, it took two 80- and 220-ton cranes to do the job.
The creation of dust in the sintering process is unavoidable, and electrostatic precipitators usually collect mostof this dust. thyssenkrupp claims it is setting new standards in air cleaning with its large fabric filters and collecting even the smallest dust particles.
The sinter plant in northern Duisburg consists of three belts. A fabric filter for the smallest belt has been in operation since 2011. The filter unit on the largest of the three belts was commissioned in 2017. Now it’s time for belt number three. “The fabric filter system in Duisburg is among the biggest and most effective of its kind in the world,” says project manager Tibor Hänsel. (thyssenkrupp)

Thyssenkrupp’s climate targets in line with global climate agreement
The Science Based Targets initiative (SBTi) has approved thyssenkrupp’s climate targets. At the same time the organization has confirmed that thyssenkrupp is acting in line with the goals of the 2015 Paris climate conference, where the international community agreed to limit future global warming to well below two degrees.
The SBTi is a collaboration between CDP, the United Nations Global Com- pact, World Resources Institute (WRI) and the World Wide Fund for Nature (WWF). Its aim is to establish science-based climate targets as standard business practice, by defining and promoting best practice in science-based target setting. To this end, the targets defined by companies are subject to an extensive independent assessment based on the latest climate science. There are currently only 10 German companies whose climate targets have been approved by the SBTi.
Thyssenkrupp recently announced that it aims to become climate-neutral by 2050. To achieve this, the company has set two binding medium-term targets which have both been validated by the SBTi: Compared with the base year 2018, emissions from production and sourced energy (scope 1 and 2 greenhouse gas emissions) are to be cut by 30 percent. This target is in line with an emission reduction pathway of “well below two degrees Celsius”. (thyssenkrupp)
