Diamond celebrations for Krenn The champagne corks have been popping in the German city of Neusäß as Krenn staff celebrated the company’s 60 th anniversary – the diamond anniversary! In 1947 the spring specialist Albert Krenn senior founded the company at Augsburg for the production of technical springs, lathing the springs by hand with his wife, Zenta. Two years later the company founder and skilled toolmaker developed a new kind of steel cutter for the building industry – a tool that is still in production today. At its 10 th anniversary the fast-growing company moved into newly-built rooms in the neighbouring city of Neusäß, and in 1975 Albert Krenn junior, the son of the company founder, took over the business. In order to better concentrate the company’s resources, the manufacturing of springs was stopped and the production of steel cutters with three- edged replaceable blades was extended. Krenn now represents Europe’s most extensive steel cutter programme, and apart from the ‘classic steel cutters’, the manual steel cutters, and pneumatic tools have been part of production since the 1980s.

This production has also now extended to include electro-hydraulic steel cutters, as well as special tools for the cutting of chains, wire ropes and other material. The most powerful cutting tools have a cutting capacity up to 50mm in diameter. During the last few years the accessories range has been enlarged by products for more efficient working processes, among them steel strapping cutters, balancers and suspension bars. “We are looking ahead with a positive feeling, because

we have cutting solutions for all kind of needs,” said managing director Albert Krenn. “Due to our policy of enlarging our product range, it was possible to conquer important business fields.” Krenn also produces a catalogue for the complete product range, which is also listed on the company’s website.

l SMS modernisation of Tata mill

Tata Iron and Steel, India, has awarded SMS Demag a contract for the modernisation of its hot strip mill in Jamshedpur. For the roughing mill the contract includes the replacement of the drive trains, the installation of new hydraulic adjusting systems, as well as a new Level 1 automation system with gauge and width control. For the finishing mill SMS Demag will supply new drive trains for mill stands F1 to F5. The SMS-designed and built compact hot strip mill went in operation in 1993, producing around 3.1 million tons of hot strip per year. Production after the revamp can be raised to more than 3.5 million tons per year. The rise in production will be accomplished by increasing the drive power in the roughing stand and finishing mill. An important factor is the 25% rise of power level in the roughing stand, which allows the number of passes to be reduced and makes the design of pass schedules easier. To be able to transmit the higher torques, new drive spindles, larger work rolls and Morgoil® bearings with higher

load-bearing capacity as well as modified roll chocks will be installed. In the finishing mill the power of the motors will be increased by around 10%. SMS Demag will replace the main gear units of F1 to F4 and the pinion gear units of F1 to F5 or their gear wheel sets. On F1 and F2, new Sieflex® gear spindles will be installed. A detailed concept was developed together with Tata Steel in order to minimise the times of production stoppages that are needed for the revamping job. The roughing-stand area will be modernised in the autumn of 2008 as part of an 18-day shutdown. Work in the area of the finishing mill has been scheduled for the summer of 2009 during the regular short-time and continuous shutdown periods.
