India: JSW Cement has launched its ‘Comp Cem’ product in Goa. It is a blend of clinker, ground granulated blast furnace slag and fly ash, according to the United News Of India. The new product is intended to help the cement producer expand its distribution network in the southern and western parts of the country.

India: JSW Cement plans to increase the production capacity to 3.6Mt/yr at its Salboni grinding plant in West Bengal. The unit has a capacity of 2.4Mt/yr at present, according to the Economic Times newspaper. The cement producer plans to strengthen its presence in eastern India starting with West Bengal, Bihar, Odisha and Jharkhand. The plant manufactures Portland Slag Cement and it hopes to tap into local demand for this product with the upgrade.

World: Global steel production rose by 4.6% year-on-year to 1.81Bnt in 2018 from 1.73Bnt in 2017. Data from the World Steel Association shows that production rose fastest in the Middle East, Africa and Australasia. Asian production rose by 5.6% to 1.27Bnt and North American production grew by 4.1% to 121Mt. European production remained static at 312Mt, with a slight dip in the European Union (EU) balanced by slight growth in the Commonwealth of Independent States (CIS). China remained the largest steel producing country, with 9.28Mt in 2018. It was followed by India, Japan, the US and South Korea.

India: JSW Steel has signed a 10-year agreement with US-based Harsco for a range of mill services. Harsco will provide JSW Dolvi in Maharashtra with on-site slag handling services including under-furnace digging, ladle wrecking, and hot slag transport. No value for the contract has been disclosed.

India: The slag yard at the Visakhapatnam Steel Plant in Andhra Pradesh has collapsed. No injuries were reported during the incident, according to the Hindu newspaper. The cause of the accident remains unknown. The slag yard was built at the time of commissioning of the steel plant. An official said that production remained unaffected. Slag from the steel plant is supplied to cement and brick producers.

India: Engineering company Paul Wurth has released details on a new blast furnace it supplied for the Steel Authority of India’s (SAIL) Bhilai Steel Plant in Chhattisgarh. It supplied, with Larsen & Toubro, a 2.8Mt/yr blast furnace for the site that was commissioned in February 2018. The unit was the eighth furnace at the plant following seven mid-size furnaces of Soviet design built from the 1950s to the 1980s.

Slag processing equipment for the furnace included an Inba slag granulation unit with a cooling tower. Other general equipment supplied for the project included: copper and cast iron staves; a 2H Bell Less Top charging syste
m with pressure equalizing valves and bleeders; cardan-type tuyere stocks; a hot stoves plant of three internal combustion chamber stoves with waste gas heat recovery and process valves of Paul Wurth design; pulverized coal injection based on dense-phase conveying with three injection hoppers and 70t/hr capacity; a top gas cleaning plant with axial cyclone; annular gap scrubber and downstream energy recovery turbine. Paul Wurth also supplied its BFXpert Level 2 automation system to allow and control of the plant operation.

Paul Wurth noted that a particular challenge of the project was to fit the new blast furnace into a brownfield building site. In particular, the layouts of the main charging conveyor, the racks for utilities pipes and cables and the railway tracks had to be finalised with ‘unconventional’ solutions.

Blast Furnace 8 at Bhilai is the largest blast furnace put into operation by Paul Wurth in India so far. It has an inner volume of 4060m³, a hearth diameter of 13.4m, four tapholes and 36 tuyeres. The nominal production is 8030t/day of hot metal.

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.

India: The Ministry of Steel has asked that the Ministry of Agriculture examine using slag from steel and iron production as a fertilizer. The government is particularly interested in using slag in areas with acidic soils, mostly in the eastern part of the country where productivity is lower, according to the Financial Express newspaper. 49M hectares of the country’s arable land has acidic soils from a total of 142M hectares total land that can be farmed.
