Housingless 2-high mill stands modernise bar mill

State-of-the-art housingless 2-high mill stands as continuous finishing mill trains in two rolling lines are to replace old, labour-intensive 3-high stands in a cross-country layout at a US bar mill.

Morgan Construction Company has received a major contract from Chicago Heights Steel, of Chicago Heights, IL, for the modernization of its bar mill.

This is the second contract that Morgan has received within the past three months for upgrading American bar mills.

Pradip Ghosh, Bar Mill Sales Manager, in announcing the contract, said, "We are providing Morgan's state-of-the-art housingless 2-high mill stands as continuous finishing mill trains in two rolling lines.

These stands replace the old 3-high stands of the three rolling lines that are in a cross-country arrangement and are labor intensive.

The modernization plan includes mill upgrade of the flange and the head rolling lines and cooling bed upgrades for the two lines to receive rolled products on to the beds at higher speeds.

The scope will include the design, manufacture and supply of equipment and site supervision services for erection and commissioning.

"When complete, Morgan will provide Chicago Heights with 10 on-line and 10 off-line mill stands with quick-change transfer cars.

In addition, we will supply mill guides, a down-ender, a roll change robot and two crop shears.

For the two cooling beds, Morgan will replace the existing sweep arms with brake slides and individually driven rollers and will provide a new dividing shear for the flange line cooling bed as well as extend the head line cooling bed enabling charging and handling of longer rail lengths from the reheating furnace.

"Morgan Process Control" he added, "will also upgrade the existing mill electrics.

When completed, the upgrade will enable the mill to reduce manpower, reduce downtime, improve the product quality and maintain its output, while reducing the number of rolling lines from three to two.

Founded in 1893, Chicago Heights is just one of the four U.S.

mills that produces special shapes such as fence posts, tee-posts, flare channels and angles for the agriculture industry.

The bar mill produces these products by slitting of scrap rails used as feed material.

Morgan Construction Company is a designer and producer of high-quality rolling mill products and services for the metal industry worldwide.
