The vacuum melting furnace "VPDS-1" is designed for casting body parts from heat-resistant alloys and steels operating under pressure up to 60 atmospheres.

The "VPDS-1.1" furnace includes the following main units:
1. Melting chamber;
2. Melting block - 2 pcs.;
3. Left portal;
4. Right portal;
5. Capacitor battery;
6. Control cabinet;
7. Operator cabinet;
8. Electrical wiring;
9. Vacuum system;
10. Water cooling system;
11. Pneumatic system;
12. Thyristor frequency converter "TPChT-250" - 2 pcs.;
13. Rail track.

Melting chamber.
The melting chamber body is welded from stainless steel, external cooling is water. During operation, one melting block and one of the portal sealing covers are alternately connected to the side flanges of the melting chamber. A pneumatic cylinder for lifting the stoppers of the right or left melting blocks is mounted on the upper flange. Two pneumatic clamps are located on both flanges of the melting chamber.

Melting block (2 blocks).
Each of the melting blocks includes:
– Melting furnace
– Mold heating furnace
– Mold movement mechanism
– Thermocouple inputs for 12 thermocouples;
– Melting tank movement trolley carrying a cover, water-cooled support brackets for the melting furnace and mold heating furnace, a condenser battery and a pressure and drain manifold for cooling all elements of the melting block.

Left portal.
The left portal is designed to move the process sealing covers to the melting chamber and to open it.
The cover (covers) are moved along a rail track via a chain transmission. The covers are suspended by movable lugs. Water cooling, from the shop main.

Vacuum system.
The vacuum system is designed to create a vacuum in the melting chamber to meet the technological requirements of the casting process of heat-resistant alloys and steels.
The vacuum system is controlled in manual push-button mode.

Water cooling system.
The water cooling system is designed to cool elements, including purchased products, operating in a high-temperature zone or creating a high temperature.
The water cooling system consists of three pressure and drain manifolds.
Two manifolds are located on two melting blocks and provide cooling of all elements. The third (stationary) provides cooling of the melting chamber, two portal covers, as well as vacuum slide pumps.

Pneumatic system.
The pneumatic system is designed to control the pneumatic clamps for sealing the lids of the melting blocks and portal blocks, for the operation of the pneumatic cylinders of the casting cooling air duct, for raising and lowering the melting crucible stopper during furnace operation.

Thyristor frequency converter "TPChT-250".
The thyristor frequency converter "TPChT-250" is designed for autonomous operation as a module of the furnace power supply system.
The converter is equipped with a fully controlled rectifier for stepless smooth power regulation, as well as a system for stabilizing the level of consumed power, fully automatic control of the inverter, ensuring full and constant power consumption with an optimal loading system.

Rail track.
The track is designed for the movement of trolleys along it, carrying elements of the melting blocks and collectors of the water cooling of the blocks. The track structure is welded from channels, to which the guides are attached.
