Quick Roll-Changing in Steelstrip Production

Siemens simplifies the production of steel strips: A new technology is making the exchange of pinch rolls in hot strip mills faster and more efficient.

The patented process reduces the time needed to replace pinch rolls in the down-coiling area by several hours, down to about ten minutes. Siemens developed an exchange cassette that makes it possible to quickly replace the entire unit with a new one.

The possibility of quick roll-changing reduces repair times, increases yield of the mill and boosts flexibility of changing between different products. As a consequence, it becomes easier for the producers of hot strips to reply to changing customer requirements.

Moreover, strips with consistent quality can be produced over a longer period of time. Cleaning and grinding of pinch rolls can now be done offline which improves strip quality and increases working safety.

Such hot-strip mills roll steel slabs up to 35 tons heavy into strips up to two meters wide and only one millimeter thick. The steel strip is still at temperatures of up to 600 degrees Celsius when coiling under tension between the pinch rolls. If the surface of a roll becomes damaged, the quality of the strip surface suffers.

In order to produce the highest quality steel, the rolls must be as freshly refurbished as possible. In order to prevent production stops caused by replace times up to 8 hours, these rolls need to be manually cleaned while production is under way.

By using the new cassette, the new pinch-roll quick-exchange unit from Siemens enables the roll replacement process in only ten minutes. All mounting connections, incl. the universal shaft release automatically. Then a bay crane is used to lift the cassette, with the two rolls, out of the pinch-roll unit and to put a freshly cleaned one in place.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
