BHUSHAN POWER & STEEL, India

BHUSHAN POWER & STEEL Ltd. completes the last stage of the phase II expansion program. The company with registered office in New Delhi was established in 1970, and today it is one of the top Indian steel producers with seven world class manufacturing facilities at four different locations in India and an annual turnover of more than 750 Million US $.

One of the world’s most modern combined wire rod and bar mills will be installed adjacent to their new integrated steel plant in Jharsuguda in the state of Orissa. The core technology of this new 500,000 tpy rolling mill is a 3-roll Reducing & Sizing Block [RSB] of the latest generation of FRIEDRICH KOCKS GmbH & Co KG, Hilden / Germany.

The order comprises the design, supply, erection and commissioning of a 4-stand 3-roll RSB with a nominal roll diameter of 370 mm. The Reducing & Sizing Block is prepared for a possible future extension to five stand positions and will be implemented after stand No. 18 of the 2-high roughing and intermediate mill. As a finishing block, the RSB rolls finished straight bar lengths within the range of 16.0 to 80.0 mm Ø and hexagons within the range of 18.25 to 50.0 mm onto the cooling bed as well as bar in coils of 16.0 to 60.0 mm Ø. As a pre-finishing block, the RSB produces all necessary pre-sections for the downstream wire rod finishing block.

An extended “free-size” range of up to ± 1.5 mm from the nominal size allows rolling of a variety of sizes with tightest tolerances only by adjusting stands and guides via remote control. The optimum adjusting values for motor speed, rolls and guides as well as gear steps depending on the final product are calculated by the Bar Mill Configuration System (BAMICON). The adjustment is done automatically within max. one minute. This allows for a trouble-free, economic production of high quality bar.

Whenever the finished dimensions exceed the “free-size” range the quick stand changing system allows to change stands in less than five minutes. Therefore, any size can be rolled without any restrictions with regard to availability of the complete mill by using a minimum number of roll sets and stand changes.

In order to meet the quality demands of a most modern rolling mill with optimum economy, BHUSHAN POWER & STEEL Ltd. as the first company in India has decided with a perspective for the future for the trend setting RSB-technology.
