APPLICATION
The furnace is designed for melting aluminium and aluminium alloys. The equipment can also be used for melting non-ferrous metals with fusion temperatures of up to 850oC.
CONSTRUCTION
The construction of the furnace is a welded unit in the shape of a cylinder built up of shaped and sheet steel. The heating chamber is built up with interlocked bricks which accommodate the heating coils. The furnace is heal-insulated with heat-resistant ceramic tiles and asbestos sheets. A crucible made of cast-iron is fitted into the furnace. A breakdown opening on the bottom of the furnace allows for the melted metal to flow out into a breakdown pit in case of damage to the crucible. A cover lilted to the upper part of the furnace seals the opening of the crucible. It is hand-operated by a special mechanism which lifts the cover and turns it round the vertical axis. A safety block terminal is welded to the jacket of the furnace. The heaters are connected to the block terminal. The temperature in the heating chamber is regulated by a thermocouple and a thermoregulator. The switching equipment is fined to the electric panel.
INSTALLATION AND OPERATION
1. The user installs the furnace in a special concrete pit in compliance with the operating instructions.
2. The equipment should be grounded.
3. The furnace is dried up and put into operation in accordance with the operating instructions.
4. The following operating precautions should be taken:
- the furnace should not be heated to temperatures exceeding the indicated working temperature;
- the good working order of the automatic heat regulation equipment should be checked periodically; the connections between the heating elements as well as the power supply connections should be examined regularly for possible loosening up;
- the friction parts should be lubricated regularly with antifriction grease.
The normal, trouble-free operation of the equipment is guaranteed under the following operation conditions:
- ambient temperature +5oC - +45oC
- humidity up to 80%
- altitude up to 1000 mm.
