The sound of pressing.
An open-die forging press, the 40/45 MN is fitted with five hydraulic cylinders; the three main cylinders with a variable force are used for the actual forging, whilst the return cylinders lift a moving cross beam to its original position. For open-die forging, saddles with different working surfaces are used.
This press handles the largest (45,000kg) ingots for forging round, square and flat bars of various dimensions, various cylinders, discs, rings and bushes.
Metal Ravne is the legal successor to Železarna Ravne. The company's range includes a steel plant programme, which starts the production of all their rolled and forged products. Due to technological modernisation over recent years, the company has all the most important machinery for the production of high-quality steel, including a 45t UHP electric arc furnace, a vacuum ladle furnace and a state-of-the-art ‘teeming pit’ for high-class conventional ingots. Their range of products includes ingots, billets with rounded edges and wide flats, with round, flat and square sections, forged bars, machined forgings, discs, bushes, etc.
