The new cooling system at GMH, including the first element of the waste gas duct, was completely designed as an evaporative cooling system. This paper analyzes the project charateristics as well as the opportunity for similar heat recovery in EAFs in North America.

Advances in software and hardware technology, as well as strict cooperation with customers, has made it possible for Pomini Tenova to design systems that move from automating operations to automating decisions with regard to roll disposition and repair in the roll shop, decisions that previously were left to skilled operators.

The recovery of hydrochloric acid from spent pickling liquor by pyrohydrolysis is not only environmentally advantageous in that it removes the need to neutralise and dispose of spent acid and that it reduces water consumption. It is also highly cost-effective, as it eliminates disposal costs, reduces the cost of replacement acid and generates a valuable oxide byproduct.

Tenova has built two 1,800tph continuous ship unloaders (CSUs) at the Italian Port of Brindisi for Enel’s ‘Federico II’ 2,640MW power station. Bulk materials handling systems supplier Tenova TAKRAF, was one of the world’s first manufacturers to tackle environmental issues involved in coal handling, developing innovative continuous unloading technology solutions to prevent coal dust emissions into the air.

Conventional electrolytic tinning lines using soluble tin anodes have high maintenance requirements not only to replace consumed anodes but also because the electrolyte has to be periodically drained, and diluted as tin dissolves from the anode faster than it is plated onto the strip. Tenova has developed a new low-sludge tin plating process using insoluble anodes and a tin dissolution plant linked to the electrolyte circulation circuit to replenish the plated out tin.

Sound industrial tradition, constant commitment to product innovation and associated services, integration and active collaboration with the iron and steel reality of the Techint Group: these are the key factors which have led to Pomini achieving worldwide leadership in the roll grinder market.

The Submerged Arc Furnace (SAF) technology is continuously evolving toward the goal of bigger, safer, cleaner and more effective operations. Tenova Pyromet is supplying the industry with furnaces for ferroalloy smelting, base metal refining, slag cleaning, and waste product treatment.

Using a process control and optimization system first developed for EAFs, an advanced statistical methodology can predict end-point carbon from off-gas composition trends and process parameters.

The Energiron Process, based on the ZR scheme, is a major step in reducing the size and improving the efficiency of direct reduction plants.
