Ideal bearings for cost-optimised operation of continuous casting machines
Schaeffler offers steel manufacturers a practical and future-oriented solution with its sealed spherical and cylindrical roller bearings for continuous caster support rollers, suitable for both new and existing caster designs. The use of sealed bearings enables longer caster runtimes and lower operating costs, which contributes to more environmentally friendly steel […]
High temperature baking-resistant Cr-free passivation coating for aluminised steel
Inorganic CrIII passivation or organic Cr-free passivation/TOC are commonly applied on aluminised steel coils to further enhance corrosion resistance. However, the poor machinability of inorganic CrIII passivation and poor baking resistance of organic Cr-free passivation/TOC coating limit their application. Henkel has, therefore, developed a new inorganic Cr-fee passivation coating, BONDERITE […]
Steel production and CO2 emissions: a growing global concern for manufacturers?
The world steel industry is a major emitter of greenhouse gases but is strenuously increasing its efforts to decarbonise through development of lower CO2 emitting processes and increased recycling of both steel products and steelworks’ so-called ‘by-products’. Harsco has been involved in recycling and by-product management for many years, working […]
MIDA endless and direct casting and rolling: the Danieli way to energy efficiency and CO2 reduction
Danieli’s minimills based on MIDA endless and direct casting and rolling processes are now well established worldwide, providing greater productivity, lower capital and operating costs and lower greenhouse gas emissions than hitherto possible. The technology and plant examples are described.
Energiron – effectively decreasing CO2 emissions in steelmaking
Energiron direct reduction technology complies with the world’s strictest environmental regulations, producing signifi cantly less CO2 than alternative processes. It also allows the products generated during the reducing reactions of iron ores to be used as by-products.
From liquid steel to rolling: concepts and applications for higher efficiency and zero waste
Green technologies are those that reduce emissions, waste by-products and resource consumption; increased process efficiency directly results in decreasing energy consumption and resource utilisation. Danieli has a long record of environmental achievements and process developments; concepts and examples are described.
Hot blast system development: technology, operations and campaign management
The hot blast system is key ancillary plant equipment with respect to safe and stable operations during a long blast furnace campaign. Hot blast stove designs have been optimised to such an extent that in some cases, their lifetimes have surpassed the campaign lengths of the associated blast furnaces by […]
Sustainable steelmaking – A strategic evaluation of the future potential of hydrogen in the steel industry
As a result of declining availability and quality of raw materials, environmental pollution and increasing public pressure, countries are being urged to deal with the topic of an energy system transformation whereby fossil energy-intensive industries such as the steel industry have to change their business models and technology portfolios in […]
Peak BOF steelmaking has occurred
The last five years have seen a significant rise in the production of steel via the electric arc furnace (EAF) route, particularly in China. It has resulted in the first fall in the percentage share of steel made by the basic oxygen furnace (BOF) route, and so is a significant […]
Process control on android system ‘goMobile’
John Cockerill has developed ‘goMobile’, a WiFi-based android system to use mobile phones and tablets to acquire data, store, display and operate equipment to enable operators to work more efficiently from any location. Mobile devices can access control systems through customised gateways.
