Motovilikha Plant is one of the oldest in Russia. It saw the daylight in 1736. At that time it was a big copper-smelting plant. In the end of the XIXth century it was rebuilt into machine-building. That was the beginning of the artillery production. Just in time. During the First World War one fifth of all the artillery was produced here as well as during the Second World War. Nowadays it produces modern artillery mounts, mortar launchers and other “useful” things.
This building has a great security. “Normal position of the doors – closed”.
Modern missile launchers are made of simple scrap metal. It is delivered here in wagons, then unloaded, weighted, and if there is still not enough – the wagons are also taken to pieces.
With help of this magnetic crane metal pieces are loaded to the container.
Then it is put into a big scoop. For the present, it doesn’t matter how much scrap is inside. It’ll be counted later.
A special man is doing usual scheduled works.
Full of pieces of metal scrap, the scoop is going to the furnace.
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.
The scoop is going away and the boiler is getting closed. Electrodes are put into the boiler and the second act begins.
This flame gun helps the furnace to smelt the metal.
Everything is controlled from this place. Here is all the information and the remote-control of the furnace.
But people here don’t trust the computer so much. Through a special window a specialist is putting a probe with sensors.
This how it looks before.
And this is after.
Here they are – electrodes. The same concept as in electric welding.
New electrodes not far from that place. They will replace the old ones when they completely burn.
The process lasts about 2 hours.
When the metal is done, the boiler goes to the next workshop.
Here one more sample is taken and new additional ingredients are added.
The boiler goes further and loaded to the cart.
Another boiler is waiting for the metal. Here the metal will be boiled.
Сhemical admixtures will influence the type and the quality of the alloy.
Add some, according to the recipe.
And put a lid.
That what is happening inside the boiler is on the screen.
Taking a sample by hand. This job isn’t easy at all. The temperature is 1500 C.
