Article in Chinese - While a number of drawbacks of conventional tinplating processes can be overcome by using insoluble anodes, their use can have some other disadvanrages. Tenova in cooperation with CSM Centro Sviluppo Materiali in Rome, has overcome those to create a modern insoluble-anode tinplating process.

The recovery of hydrochloric acid from spent pickling liquor by pyrohydrolysis is both environmentally appropriate as it removes the need to neutralise and dispose of spent acid and reduces water consumption, and it is also cost effective as it removes disposal costs, the cost of replacement acid and generates a valuable oxide by-product.

Tenova Goodfellow has developed a reliable real time off-gas measurement and control system called Goodfellow Expert System Optimization Process (EFSOP®). The EFSOP® system has been proven in the harsch environment of EAF steelmaking with more than 200,000 analyzed heats do date.

Article in Spanish - A cutting -edge 3-D modelling tool is now being to design the latest version of the Tenova Pomini roll grinder machine HD409 by simulating the key component parameters so enabling any necessary modifications to be made prior to manufacture.

Article in Russian - Tenova, is a major world-wide supplier of advanced technologies, products and services for the metal and mining industries. Just as these industries are consolidating, so is Tenova, by acquisitions designed to continuously invest in R&D and innovation to extend and keep its products at the top level for quality, energy savings, and environmental safeguards.

Article in Spanish - The first industrial scale direct reduction plant back in the mid 1950s was a success on a number of fronts for Tenova HYL in that it provided a quality pure iron feedstock for the EAF and led to a burgeoning DRI industry worldwide, that today has adopted "green" credentials with reduced emissions and hot charging of DRI to the EAF.

The possibility of successfully coupling a DRI plant with a coal gassifier system will provide new perspectives in ironmaking. New possibilities are thus opened to introduce gas-based direct reduction technology in markets where there is low availability of natural gas at competitive price, but high availability of coal.

Article in Arabic - The Expert Furnace System Optimisation Process (EFSOP®) is now well established in EAF steelmaking. Similar control concepts are applicable to other furnace systems and a trial is underway at Hamilton Steel where EFSOP® has been applied to a BOF converter.Development projects also continue for its application on cement kilns and power station.

In the mid-1990's HYL (now Tenova HYL), based in Mexico, began promoting the advantages of its new generation of direct reduced iron (DRI) containing high level of carbon (>3.5%).
