Mould grinding

The sound of mould grinding.
In the recording, a member of the maintenance staff is repairing an ingot mould with a handheld grinding machine.
After a certain period of remelting, the ingot mould, which is made of copper, becomes slightly deformed and has to be repaired.

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.
