The electrical furnace is already ready to the new portion of the metal scrap.
The scoop is hovering in the starting position.
The bottom of the scoop opens and the scrap falls into the boiler of the furnace.
Then sparks are diminishing on the floor and it seems like it's the end. There is complete silence.
Then the very process begins. According to the sounds, something enormous is happening inside.
Impact, bright flash and new sounds. The floor is shivering.
