EAF COPPER Components

Improving EAF performance with right materials

Electrode Contact Pad

Water Cooled Cable

Water-cooled cables are now being used for the melting arc furnace and the melting induction furnace. ATS Metalurji is working with  leading manufacturers in this field, is supplying reliable and high quality water-cooled cables, utilizing to the full its vast experience and research, and is achieving highly satisfactory results. ATS Metalurji Water-Cooled Cables are in great demand not only inTurkey, but also from overseas, and are contributing to the optimum operation of electric furnaces all over the world.

EBT Burner & Pannel

A newly designed oxygen wall-mounted supersonic nozzle generating a focused stream of oxygen that maintains its supersonic velocity for more that 2 meters without using a flame shroud. This allows to generate the benefits of conventional sidewall flame-shrouded injectors without the need for gaseous fuel, thus reducing the operational cost of EAF operations, when predominant flat bath conditions eliminate the need for the burner function.

Shell Burner & Pannel

Together with new panel design you gain the ability to install the panel close enough to the steel bath for good decarburization but minimize the distance the panel protrudes into the furnace. With a lower profile in the EAF, there is less chance of damaging the panel during the charging process. The small size of the panel also allows for easy installation and removal from the furnace sidewalls.


Re-sheathing, replacement or recovery of conductors, terminals or parts thereof. ATS Metalurji guarantees your productivity by minimizing down-time of your cables by a fast and customized answer.ATS Metalurji can repair cables regardless of their design or brand.


The vacuum oxygen decarburization furnace (“VOD”) is mainly used for the production of stainless steel. The plant is basically designed as a tank degassing plant which is additionally equipped with an oxygen blowing lance and other related equipment. Due to the reduced CO partial pressure under vacuum conditions, decarburisation of high-alloyed steel grades to very low carbon contents is possible.

Steam jet pumps are designed in 4 or 5 – ejector stages. The motive steam is condensed by contact cooling water condensers. The steam jet pumps are designed as full steam pumps or as Hybrid pumps in combination with liquid ring pumps.

VOD Furnace Steam jet pump features

• Reliably high suction capacity at deep vacuum condition as well as in the mid-range for heavy process gas loads

• Robust long-life design matching steel plant demands

• Simple maintenance required

• Low wear and tear

• Vacuum control by needle valves

Thorough carbon removal is achievable with a Vacuum Oxygen Decarburization (VOD) furnace. The VOD is basically a tank degasser equipped with an oxygen lance compared with VD, but specifically configured to withstand the heat load from an intense CO emission. VOD is normally used for deep decarburization of highalloy steel grades, usually to remove carbon without affecting chromium content in the production of stainless steel grades.

The highly advanced IPC, software and computer of VOD furnace process is available from the company by monitor the motion and process of related machine.The main components of VOD equipment are tank, tank cover, cover movable car, vacuum pump and control system etc.


Vacuum Degasser (“VD”) is used to reduce the concentrations of dissolved gases (H2, N2, O2 ) in the liquid steel; Homogenize the liquid steel composition and bath temperature; remove oxide inclusion materials from the liquid steel; and, provide the means and technical conditions that are favorable for final desulfurization.

During operations at the VD, the liquid steel is stirred to promote homogenization by percolating argon gas through a single refractory stir plug arrangement in the bottom of the ladle. The argon connection to the ladle is established when the ladle is set in place inside the vacuum tank

The vacuum tank is evacuated to the required operating pressures by one of three ways: steam jet ejector, steam jet ejectors and a water ring pump, or, mechanical pumps. Emissions are evacuated through a vacuum pumping system and are collected prior to the pumps or they are discharged under water contained within a weir wall-equipped concrete hotwell. The process gases, including those entrained in the intercondenser discharge water, are exhausted from the hotwell via a motor driven fan to a vent stack equipped with a flare burner. Hotwell water is pumped to a cooling tower of the contact water system.

VD Furnace Dry mechanical pump features

• Lower operational costs compared to steam jet pumps;

• No contact cooling water needed;

• Compact and modular installations;

• Vacuum control by gas dilution;

• Redundant systems can be installed upon Customer’s request
