Production

The production consists of:

1. Line for the production of aluminum cylindrical billets
2. Line for the production of aluminum cylindrical billets 
3. Homogenization line
4. Pollution abatement system.

1. Line for the production of aluminum  cylindrical billets

Consists of:

1. Hydraulic machine for loading to aluminum Melting furnace;
2. Melting furnace for aluminum;
3. Furnace for aluminum holding;
4. Pollution abatement system;
5. Machine for semi-continuous casting of blanks with removable tables;
6. Degassing system for molten aluminum;
7. Automatic saw for cutting of aluminum billets with a system for collecting sawdust.

From the casting furnace liquid aluminum is discharged into the degassing and filtration system. During the process of discharge, Al-Ti-B ligature is fed by the ligature feeder into liquid aluminum. Degassing is performed through the argon feeding directly into the melt. 

Upon completion of degassing, liquid aluminum enters casting table of semi-continuous casting machine, where it is crystallized and drawn into cylindrical billets up to 7 m length.

Finished aluminum cylindrical billets are then fed to the cutting section, where they are cut into pieces of the required length using automatic saw with sawdust collection system.

Water supplied to the semi-continuous casting machine during crystallization of aluminum is heated to a temperature of 40 ° C. Water removal is performed by gravity to the pool and then to the cooling tower.

Gas burners provide required temperature in the furnace. In order to ensure explosion safety of gas combustion, the furnace is equipped with devices for gas combustion control.

2. Line for the production of aluminum ingots

1. Melting furnace (rotary)
2. Melting furnace (holding)
3. Feed channel
4. Loading window
5. Discharge channel
6. Conveyor with electric drive
7. Casting mold for ingots
8. Air cooling device
9. Device for extraction of ingots from molds

Production of aluminum alloys is carried out in a cyclic mode. Operating cycle of furnace consists of the following stages:

• Charge loading;
• Heating;
• Melting;
• Discharge;
• Slag removal.

Charge is loaded by the loader into the hopper of loading unit. Loading hopper moves to the furnace body so that the feeder tray is located in the opening in the furnace body. Heating is provided by combustion of natural gas. At the end of melting process, the melt is fed into the channel and then through the filter box is directed to the conveyor where it falls into the molds. During the conveyor movement, aluminum is cooled and crystallized.  Finished ingots are knocked out of the molds with a special device, then packed and labeled. Slag, formed during the processing of charge is discharged into a slag pot. Control and monitoring of the equipment operation are carried out from the control panel. 

3. Homogenization line

Homogenization line is designed to ensure uniformity of the structure of aluminum alloy by heating and intensive cooling. 

Consists of:

1. Homogenization furnace with natural gas
2. Loading machine
3. Cooling chamber
4. Control panel

4. Pollution abatement system

Pollution abatement system (2-line) is used for purification of exhaust gases from furnaces and hoods, i.e. processing and disposal of harmful substances contained in them. In conjunction with the furnace equipment it ensures compliance with the maximum permissible emission concentrations in exhaust gases prescribed by law. Discharge of purified exhaust gases into the atmosphere is carried out through the fireplace. Purification of exhaust gas is carried out by dry sorption with the recirculation method using the LÜHR ball rotor (integrated particle return system) in
combination with the LÜHR filter system.
