1． The name, quantity, technical specifications and fund sources of goods for tendering：
The name：5t Electroslag Furnace with Atmosphere
Quantity：1 set
Technical specifications：
1）The furnace head enables the feeding of the consumable electrode. The electrode feed system is supported by the gantry structure of the furnace head and is placed on 3 or 4 load cells. It is composed of electrode ram and electromechanical drive system. The electrode ram is driven by ball screw and is equipped with a guide system.
2）The electrode clamping device is arranged at the lower end of the electrode ram. The electrode ram crosshead is composed of a pneumatic clamping cylinder. The melt current flows along the outer wall and through the contact flange at the lower end of the ram into the contact surface of the stub.
3）The electrode feed system is driven by motor and includes the components such as servo motor and a set of ball screws.
4）The electrode position can be adjusted in "X"/"Y" direction to solve the defect of misalignment of electrode and stub in the welding process of stub outside the furnace. Adjustment is controlled with button at local station. The relevant adjustment is based on the visual judgment of the operator. The indicator at the local station shows the actual deviation of the electrode ram from the zero position.
5）An automatic slag feed trolley can be used to provide the controlled amount of slag. The starting and subsequent slags make up the total amount of slags required for the remelt process. The automatic slag feed trolley uses the movable screw feeding.
6）Closed-loop cooling water system
Three closed-loop internal cooling water systems in total, which cool down the components such as the power supply, water-cooled cables and mold respectively.
The closed-loop internal cooling water system mainly includes, but not limited to, SS water tank, heater, water pump （one for normal use, the other for backup）, heat exchanger, water flow meter, temperature meter, pressure gauge, sensor, flow valve and water distributor, etc. The pipeline of the system shall be made of SS.
All cooling water branches shall be equipped with temperature, pressure and flow rate display, visible flow indicator, alarm and interlock control, and shall be connected to the PLC control system, to achieve the monitoring of each water circuit and timely detection of water circuit failure. Failure of the flow detection instrument selected will not have any impact on the water circuit.
The cooling water inlet temperature of the mold can be controlled automatically.
7）Flue gas venting and atmosphere protection hood system
The mold assembly shall be equipped with flue gas venting and atmosphere protection hood to shield against the humid atmosphere entering the mold in the workshop. Dry air can be introduced into the mold through the annular gap between the electrode and the venting hood through a multi-nozzle jet system.
8）Full coaxial large current feeder system
The power supply network system is composed of multiple parts. Connection from the power supply to the furnace head is enabled by multiple groups of coaxial feeder water-cooled cables. The current of the furnace head is transmitted to the conductive tie rod, consumable electrode, newly generated ingot, conductive copper base plate, conductive furnace leg, and finally back to the power supply through conductive carbon brushes, where the furnace head and melt position are composed of 4 groups of coaxial conductive copper furnace legs.
9）Melt power supply
The furnace is designed to allow use of the power supply at the frequency of power supply.
Primary main inlet voltage and frequency: 6kv AC/50 Hz
Thyristor or saturable reactor is used to control the power supply.
10）Weighing system
The weighing system with high precision, temperature compensation and electrical shield shall be used.
High precision electronic measuring system with high resolution, allowing fast melt speed calculation, shall be used.
Carrier frequency technology shall be used to feed the signal into the load cell, and receive the modulated signal to avoid noise interference and zero point drift.
