Vardhman Special Steels signs order for Kocks reducing and sizing block

Kocks RSB ® with upgraded design

INDIAN steel producer Vardhman Special Steels Ltd, and rolling mill equipment supplier Friedrich Kocks GmbH & Co

KG, have signed a contract for the supply of a reducing and sizing block type RSB ® 370++/4 in 5.0 design at METEC 2023 in

Düsseldorf, Germany. The block will be part of the SBQ rolling mill in Northern India and will expand the technological possibilities in the production of special steels at this site. Vardhman is an Indian company that specialises in the production and distribution of special steels. It has become a trusted supplier for demanding processing industries. The company is based in Punjab, India and serves various industries such as engineering, automotive, tractor, bearing and allied industries. The existing rolling mill is consisting of a most modern reversing mill followed by two-high stands in H/V arrangement and is producing currently approximately 200,000 t/a SBQ in straight bars within a finished size range of Ø 20 to 90mm onto the cooling bed. The project considers the integration of a new RSB ® 370++/4 in 5.0 design as finishing block. The scope of supply includes equipment for the roll shop. The new 3-roll block enables the Indian steel producer rolling from a single pass family in the roughing and intermediate mill, significantly reducing the number of required feeders. Thanks to the unique three-roll stands, any desired finished dimension from the entire dimensional range can be rolled with a minimal number of roll sets and minimum stand changes. The setting values for motor speeds, rolls and guides, as well as gear ratios, are calculated by Kocks’ rolling configuration program Bamicon according to the desired end product. The commissioning of the RSB ® is scheduled for the end of 2024.
