Rolling Mill Monitoring

Rolling Mills Comments Off

Rolling Mill Monitoring photo rolling millsTo keep up with the high demand for steel, rolling mills must stay on schedule and in production. Whether it is a hot or cold operation, drive train system components must be kept in check with continuous rolling mill monitoring. Waiting for scheduled maintenance checks to identify potential operational problems may not be enough to avoid debilitating production downtime. Because rolling mills are working 24/7, monitoring operation must be constant to be effective.

True continuous rolling mill monitoring must encompass the entire mill operation. While vibration monitoring of select components may be effective to identify vibration problems, this will only tell part of the story. Since steel rolling involves a sequence of inter-related functions, a complete picture of the process is necessary to keep the entire system going. Such things as temperature, torque and speed will also be important to monitor. While the monitoring of separate systems working independently is beneficial, it will not provide all of the data necessary for generating an accurate assessment of conditions.

Xtek, the internationally recognized leader in drive train component technology, has made the complete picture available with the DriveWatch system, a network approach for comprehensive rolling mill monitoring. The Xtek DriveWatch™ system tracks irregularities in vibration, temperature, torque, current, speed and other parameters on a continuous basis.

Because Xtek has over 70 years of experience developing technology for the steel industry, we understand the complexity of rolling mill operations and the components involved. We have put this expertise into creating the ideal technology for rolling mill monitoring. Our engineers understand the problems caused by vibration, temperature and torque and have created a method for gathering the data needed to head off vibration issues before they occur. The Xtek DriveWatch™ system allows this data to be retrievable at any time, from any location with internet access, for 24/7 real time reporting.

Steckel rolling mills

Rolling Mills Comments Off

Steckel rolling mills  photo rolling millsGeared to high demands. If you specialize in stainless or acid-resistant grades, a Steckel rolling mill is the ideal choice for you. Why? Because these grades are usually manufactured in small batches, so the versatility of a Steckel mill compared to a conventional hot wide strip mill makes good economic sense. And it’s this flexibility plus cost-effectiveness that also makes all the difference when you produce nickel and cobalt alloys or titanium alloys.

Compact and low-cost. A Steckel rolling mill is a compact plant with an annual capacity of up to 1 million t. Much cheaper than a conventional hot stripmill, a Steckel mill finish-rolls the strip in reversing mode. It features one coiling furnace each at the entry and exit sides of the mill stand to keep the strip hot. That is how it can roll up to nine passes.

Our expertise. You benefit from our worldwide experience in building single-stand Steckel mills with extremely high rolling forces. Alternatively, you may be interested in one of our innovative revamps that significantly increase the production capacity and availability of existing plants. Our subsidiary, SMS Demag Tippins, is your specialist for tandem and heavy-plate Steckel mills. All this expertise makes us a partner you can rely on to support you with this kind of plant – wherever you are in the world. Integrated in our Steckel rolling mills are all the adjustment and control systems for strip thickness, profile and flatness that have proven their worth in conventional hot strip mills and CSP® plants. For simply outstanding rolling results.

POLYCOM® high-pressure grinding roll

Other Machines Comments Off

POLYCOM® high pressure grinding roll photo other machines steelwork and rolling mill equipment metallurgy and metalworkThe high-pressure grinding roll has proved extremely effective for the grinding of mineral raw materials. With more than 250 POLYCOM® installations in different industrial sectors, Polysius is the worldwide market leader for this technology.

60 % of the high-pressure grinding rolls installed in the minerals industry are from Polysius: the POLYCOM® operates convincingly all around the world, comminuting • copper ore • gold ore • iron ore • diamond ore • platinum ore • coal • granulated blast furnace slag • limestone • cement clinker and • other mineral raw materials.

This type of mill offers the minerals industry numerous benefits:
Low operating expenses: in comparison to other systems, both the power consumption and the costs for wear parts are significantly lower.
High throughput rates: a high-pressure grinding roll can replace several reduction crushers.
Metallurgical advantages in the downstream process stages.
Shorter delivery and commissioning times than can be achieved with other systems.

POLYCOM® units are designed for throughput rates in excess of 3,000 tph. The mill feed material can be dry or moist and with particle sizes ranging from below 1 mm to more than 75 mm. If required, the material can be dried in screens or air separators in a closed circuit grinding system.

Merchant Mills

Other Machines Comments Off

Merchant Mills photo other machines steelwork and rolling mill equipment metallurgy and metalworkAvtron has experience with drive systems installed on Merchant Mills. We have applied our SCR Retrofit and DC Drive products for the horizontal stands in the Roughing and Intermediate trains, and for alternate vertical and horizontal stands in the Finishing train.

Our drive hardware and software features are ideal for the Merchant Mill because the standard drives can perform the Cascaded Speed Reference function directly from drive-to-drive. Further, the drives can control the Shears more accurately because of the superior internal resolution and update times of the control loops. This results in a more efficient mill which produces less waste and more shippable product.

Less waste and more shippable product is also the result of the Performance View (TM) System we use for these mills. This Process Diagnostic System continuously and automatically gathers and stores all of the critical mill drive and process control data. This data can easily be manipulated and correlated to find problems on the mill faster so that troubleshooting and repair time can be minimized. Further, the data can be used to establish a �benchmark� operating condition for the establishment of a mill Predictive Maintenance Program.
