Carbon plant modernization

Modernization and reconstruction of Carbon plant should include the following:

  • Installation of additional vibro compactor for larger anodes with accompanying equipment
  • Verifying the sizes of the baking furnace chamber and related equipment
  • New anode rodding and bath treatment facilities for new technology.

Line for production of alloys in form of small ingots

 

Line for production of alloys in the form of small ingots

Investment program envisages installation of alloy production line, 30.000t/y capacity. The line consists of:

  • Two melting and casting furnaces, 35t capacity respectively, with regenerative burners and ABB stirrer.
  • Metal treatment equipment (filter, degasser, Ti-Bor Feeder)
  • Open mould ingot casting line, 7kg
  • Stacking and packing machine

The value of investment is ca 5 million euro.

Contract on delivery of equipment has been signed signed with the Turkish company Sistem Teknik.

Production on this line is planned to start in January 2019.

Strip casting and rolling line

Investment program envisages installation of strip casting line, providing product width 2000 mm and thickness 3-4 mm, which would be further rolled down to the width of 0.15-3 mm in the rolling mill.

Line capacity is envisaged in the range of 50.000-60.000 t/y.

The value of investment is EUR 50 million.

The line consists of:

  • Furnace for metal preparation;
  • Metal treatment equipment;
  • Casting machine for strip casting;
  • Rolling mill;
  • Other accompanying equipment.

Billet production line

Investment program envisages installation of billets and slabs production line having capacity of 60.000 t/y.

The value of investment is EUR 12 million.

The line consists of:

  • Two holding and casting furnaces, 30 t capacity respectively;
  • Metal treatment equipment (filter, degasser, Ti-Bor Feeder);
  • Casting machine for casting billets and slabs with equipment maintenance workshop;
  • Homogenizing furnace with accompanying devices.

Alumina plant modernization

Alumina Plant is an integral part of Uniprom-KAP.

The plant has been shut down since 2009.

The original capacity of the plant was 280.000t/y.

Restart of the plant including modernization and capacity increase is estimated to cost 35 million euro and it would be performed through the following steps:

  • Restart of the existing facilities
  • Expansion of capacity
  • First step: to evaluate what is the max. capacity when fully using the existing facilities and de-bottleneck
  • Second step: to evaluate the possibilities of reaching 400~500kt/y after carrying out the first step
  • Product quality improvement: comply with international market requirements
  • Energy Saving
  • Environmental Improvement to reach the European standard
  • Red mud storage and utilization
  • Dry mud storage and transportation
  • Recycling iron content in the red mud
  • Remove Zn O contained in bauxite
  • Possibility to produce high purity Al2O3

Smelters

New smelter

One of development projects of Uniprom-KAP is construction of the new smelter.

New smelter with capacity 140.000-180.000 t of liquid aluminum will be installed at the location of the existing potrooms of the Potline A or at new location, which shall be decided upon following the preparation of feasibility study.

  • A new corresponding electric power facility will be installed next to the new smelter, as well as the new rodding shop, bath treatment facility, fume scrubbing system and other accompanying equipment.
  • New pot technology (300-400kA pot with point-feeding system)
  • New potroom building at the location of the Potline A or at the new location of Potline C. 

Modernization of the Potline B in existing Smelter

Maximum potline capacity is 60000 t liquid aluminum per year. It is planned to examine the cost-effectiveness which should include the following:

  • Transition from alumina side feeding system to point feeding system, closing the pots by fume hood, assembly of accompanying equipment
  • Enhancing the potline current
  • Optimization of pot lining for energy saving
  • Adding the Gas Treatment Center (GTC)
