THE ELECTRODE

Monitoring and improvement detection

As Tokai, we support our customers with solutions to monitor their varying process parameters. We do

this with actual on-site and remote monitoring systems. Utilizing our advanced tools, we can gather the

data covering the operation and control of the EAF. This is, of course, only done with the consent of the

customer. We are very strict in complying with all confidentiality obligations developed with our respective

customers. Once the information is gathered, we will submit the results in easy-to-interpret reports in the

format requested by the customer. The data is also reviewed and analyzed by our experts to identify and

recommend potential improvements and optimization to the customer’s process.

Electrical measurements for process analysis and diagnosis

As part of our service, Tokai’s technical team may conduct various electrical measurements on our

customers’ electric arc furnaces. With the electrical measurement data, we can help the customer

troubleshoot potential electrical issues as well as any potential electrical improvements. The analyses

and recommendations are delivered in a comprehensive, easy-to-understand format.

By taking the measurement, we are able to offer more complete recommendations and possible actions to optimize EAF settings, which could include:

• Electrical balance (refractory wear issues)

• Melting profile

• Current level (long/short arc strategy)

• Foamy slag judgment

• Arc stability problems

• Productivity

• Melting efficiency

• Electrode consumption mechanism

• Electrode regulation dynamics

Optimization and troubleshooting by EAF experts with special tools

Tokai’s technical experts have many years of experience working in

the steel industry and are extremely well versed in the entire steel

production process as well as EAF maintenance. By utilizing

the various tools and instruments when analyzing existing

processes, they are in turn able to offer our customers

tailor-made solutions.

Combining the strength of experience with analytical and

statistical procedures, we can detect inefficiencies in the

electric arc furnace’s melting process, Tokai’s tec

hnical experts

can provide best in class recommendations to our customers.

The use of our customized tools ensures that all re

commendations

provide credible results.

Examples of our specialized services include:

• Consumption models (comparison of theoretical and actual consumption)

• Validation of increases in productivity

• Recommendations on furnace design and operation

• Assistance on commissioning the furnace

• Electricity use modification

• Control and hydraulic optimization

• Melting profile depiction

• Benchmarking (comparative process and result analysis)

Electrode care and handling

The handling of graphite electrodes and connecting/jointing equipment is critical to realize the best

performance results from the electrodes. As an additional service, Tokai is happy to provide workshops

covering the proper handling of electrodes as well as the proper use and maintenance of the

accessory equipment.

In these workshops, our team will go through, in great detail:

• Accessory handling training

• Equipment integrity check

• Jointing improvement

• On-site storage management

• Inventory management

• Training and workshops
