ArcSpec

Measure, control and optimize your EAF in real-time

The lack of visibility and changes in the process is a challenging match

Steelmaking with the Electric Arc Furnace (EAF) is an extremely energy-intensive process. Large production volumes and variance in raw materials and other process inputs make operating EAF very complicated and costly. Optimizing the process could enable significant savings in operating expenses while also improving the productivity.

The extreme conditions inside the furnace limit the visibility of the process. The use of conventional measurement methods can not withstand the heat and slag spray. This has caused inefficiencies in the process. Unnecessary use of energy, excessive wear of furnace equipment, and delays in production cause.

Until now.

Based on our patented technologies, we have developed the ArcSpec system. ArcSpec is a unique process control system that has finally enabled us to see into the furnace. The system measures, controls, and optimizes the furnace in real-time. Real-time dynamic control leads to:

Improved energy efficiency

Increased production capacity

Reduced electrode and refractories consumption

Optimize the Electric Arc Furnace process

An Electric Arc Furnace generates huge amounts of light from several sources. The arc, flames, and hot slag inside the furnace all emit light. ArcSpec measures these light sources in real-time with Optical Emission Spectroscopy (OES). Light’s spectrum gives information about the melting progression and source of the light.

ArcSpec then further analyses this information into control signals. The signals are then sent to the furnace control system to make the necessary changes to optimize the process. When to start the different phases of the process and how to control the process parameters.

Increased visibility and optimization reduces the overall process time and improves energy efficiency.

ArcSpec collects light from the EAF

The system breaks the light into spectral components

ArcSpec analyzes the data and generates control signals

The process is adjusted based on the signals

Everything as a service

We offer the ArcSpec system also as a turnkey service. Our services can consist of an assessment period prior to any final decision. All our products can be offered as a continuous service, including the use and maintenance of the system.
