Metalloinvet’s OEMK Ball Rolling Facility Producing 90mm Balls

Metalloinvest’s Alexey Ugarov Oskol Electrometallurgical Plant has implemented the production of a new type of product, balls 90 mm in

Metalloinvest’s Alexey Ugarov Oskol Electrometallurgical Plant has implemented the production of a new type of product, balls 90 mm in diameter of the second and third hardness groups, at its ball rolling facility. Balls of this diameter are intended for mills where rock mass is ground through abrasion. This makes it possible to obtain finely ground raw materials for the production of higher quality iron ore concentrate. The new products will be supplied to Metalloinvest’s own enterprises, Lebedinsky and Mikhailovsky GOKs, as well as to external consumers.

The ball rolling facility was launched at OEMK in November 2020. The facility also produces balls with a diameter of 100-120 mm, weighing 4.6 and 8kg and of 2nd and 3rd hardness groups in accordance with the GOST 7524-2015 standard.

In order to implement the production of balls with a 90mm diameter, documentation on the calibration and ball production technologies was developed, and the purchase and delivery of work roll bands and guide fittings were carried out.

The annual production capacity of the BRF is around 43,000 tonnes of rolled steel grinding balls. Metalloinvest’s investment in the project was around 1 billion roubles.
