Poland: Primetals Technologies has received a provisional acceptance certificate (PAC) from ArcelorMittal Poland for the replacement of the second LD (Basic Oxygen Furnace) converter at the Dąbrowa Górnicza steel works. The converter entered service in February 2018. It follows a previous project by Primetals Technologies to replace a converter at the site in 2016.

As in the case of Converter #1, Primetals Technologies supplied the vessel and the trunnion ring, including the Vaicon Link 2.0 suspension, for Converter #3. The converter bearings and the enclosure have also been renewed. The order included also removal of the existing vessel and assembly and installation of the new equipment. This had been handled by ZKS Ferrum, the Polish partner in the consortium.

ArcelorMittal Poland is the leading steel producer in Poland, operating six production plants in the south of the country. Its range of products includes profiles, rails, fittings for the construction, transport and mining industries, as well as flat products for the automotive industry and domestic appliances.

Russia: Evraz’s consolidated crude steel output fell by 5.5% year-on-year to 3.3Mt in the first quarter of 2018. The steel producer blamed the fall on lower pig iron production due to iron ore supply issues in relation to poor weather in January and February 2018. It also attributed the decline to technical issues with blast furnaces #1 and #3 at its Zsmk plant, a shutdown of the blast furnace #6 at Ntmk and the divestment of its Ukrainian Dmz subsidiary in March 2018. Total steel product sales dropped by 5.7% due to lower crude steel production. Sales of semi-finished products fell by 16.6%, primarily due to reduced pig iron and crude steel production. This was partly offset by a 5.7% increase in the output of finished products, mainly for the construction industry.

China: The Ministry of Ecology and Environment has banned imports of steel slag from the end of 2018. It is part of 16 scrap metal and chemical waste products, according to Reuters. A further 16 items will be banned by the end of 2019. The government’s crackdown on waste imports is part of a ‘war on pollution.’

India: Wonder Cement has ordered two vertical mills from Germany’s Gebr. Pfeiffer for its Nardana plant in Rajasthan. The order includes a MVR 6000 C-6 mill for grinding slag cement and a MPS 3070 BK mill for grinding fuel. Delivery is scheduled for early 2019 and mid-2019 respectively.

The MVR mill will feature a total drive power of 5820kW. Mixed cements will be be ground to a fineness of up to 5% R 45µm. The grinding plant will be designed to process granulated blast-furnace slag with a target fineness of approximately 4500 cm²/g Blaine and blast-furnace cements with different proportions of granulated blast-furnace slag, fly ash and gypsum and different product fineness degree. Wonder Cement has requested the option to grind relatively hot clinker in the mill while at the same time being able to reduce the cement temperature, and alternatively to use cold clinker from stockpiles.

The core components such as the tension system and the grinding rollers will come from Gebr. Pfeiffer in Germany. The grinding bowl and the gearboxes for the mill and classifier will also be delivered from Europe. Gebr. Pfeiffer’s subsidiary, Gebr. Pfeiffer India, will provide the housing parts, the foundation parts and supports of the rollers as well as almost the entire high-efficiency classifier type SLS 5600 BC. Gebr. Pfeiffer India scope of supply will incorporate most of the equipment to complete the grinding plant including the plant fan.

The MPS mill will grind petcoke with a capacity of 40t/hr to a product fineness of 2% R 90µm. It will come with a SLS BK classifier, allowing both coal and petcoke to be ground in the mill, dried with process gases and then classified in the integrated classifier. Due to the high abrasiveness of Indian coal, the mill will be designed with appropriate wear protection.

Most components of the coal mill will be supplied by Gebr. Pfeiffer India. The housing and foundation parts, the grinding bowl and a large part of the power-transmitting parts will be manufactured in India. Setting up the new MPS mill is planned to coincide with the commissioning of the entire kin line.
