NKMZ has successfully performed updating of 320/150-mm combined wire rod mill at Moldova Steel Plant. The equipment designed and manufactured enabled to realize two-strand rolling technology. As a consequence, the annual mill production of bar stock and wire rod has increased from 500 ths. t to 700 ths. t.
