Steel Making Solutions

Steel Making Solutions by Agellis

Based on our two product platforms, EMLI (ElectroMagnetic Level Indication) and VISIR (Vision and Infrared), we supply an array of solutions to control the process and ensure operation safety.

EMLI - EAF Level

Electromagnetic Steel Level Tracking in EAF

The AGELLIS EMLI-EAF Level is a unit for recording critical furnace level data whenever required. The system can be used in all EAF furnace types where molten metal access is possible, a suitable slag door manipulator is already in place or a manipulator is to be installed and the process requires knowledge of bath and hot heel levels.

 

By combining steel plant proven electromagnetic measurement with your slag door manipulator that already takes temperature and/or metal samples, you can have a system which is both innovative and reliable. By equipping your manipulator with the Agellis electromagnetic sensor sword, you will be able to detect the metal levels that you need to know in your furnace, thus assisting your decision making. Knowing your metal bath level whenever you require it and having an accurate hot heel level measurement is critical to furnace process optimisation.

       

The EMLI-EAF Level system has unequalled precision and repeatability. No other system or solution is able to deliver as many measurements per heat with such high precision. The fact that the system is probe independent and does not interfere with actual practices ensures the industry’s best performance at the lowest cost.

 

Do you already have a Slag Door Manipulator?

Then you just need to add (retro fit) the EMLI-EAF Level system to your existing system. You will still be able to perform temperature or oxygen measurements just as before, but will also get a precise steel level in the same sequence. This means no changes are made to current operator practice and no special probes are required.

 

You do not have a Slag Door Manipulator?

Agellis can provide complete systems, including slag door manipulators from leading manufacturers, delivered with the unique EMLI-EAF Level system pre-installed.

EMLI - FurnaceSlag

Electromagnetic Slag Detection for Furnaces

AGELLIS EMLI-FurnaceSlag constantly monitors the steel flow during tapping of the furnace and provides alarm outputs at the onset of slag in the stream. These outputs can be used to immediately end tapping by initiating gate/stopper closure or by changing furnace tilt angle, while at the same time giving visual and audible alarms.

     

Sensors/cabling are customized to fit any furnace. Tap-hole sensor arrangement requires only minimal modification to existing equipment. The Management Unit is capable of running multiple Control Units of the same or different EMLI system types. This enables the user to expand the system to run extra slag detection systems and/or other EMLI measurement devices. Steel plant tested components make the EMLI System extremely durable with low maintenance costs. Sensors require no special handling or cooling.

VISIR - MetalDetect

Metal Detection During Deslagging

Agellis VISIR-MetalDetect improves your metal yield through detection and control of metal losses in the deslagging process.

              

 

Why VISIR-MetalDetect?

The VISIR-MetalDetect system is designed to monitor the ladle or furnace deslagging operations in order to detect when metal is being poured. Thus a minimal amount of metal is lost and yield improved.

MetalDetect uses a thermal camera and vision technology in order to monitor the deslagging operations in real time.

By using the VISIR-MetalDetect system you will be able to assist operators to control their deslagging metal losses in a safe and secure manner. The thermal camera mounted behind the deslagging stream will monitor the process automatically and inform the operator when metal is detected so that they can modify the process quickly and safely.

By better control of the deslagging process variations and ensuring that the metal losses are significantly reduced, yield improvements and consistency can be achieved.

The VISIR-MetalDetect system will automatically track and store vital information for each heat and make sure your yield and quality assurance program is met every time.

VISIR - LadleDeslag

Ladle Skimming Monitoring

The VISIR-LadleDeslag system monitors ladle skimming operations to help achieve clean ladle steel for further process operations, while at the same time ensuring that excessive metal loss is avoided. VISIR-LadleDeslag cameras and software evaluate the ladle surface slag content and feeds information to the operator when a sufficient skimming has been achieved.

          

 

Why use the VISIR-LadleDeslag system?

Are you experiencing uncontrolled sulphur increases in the BOF? Are you experiencing uncontrolled reoxidation during ladle treatment? Do you feel a need to narrow down process variations in the final steps of processing? Do you see that the deslagging performance varies considerably from ladle to ladle and is operator dependent?
If you associate with any of the above, VISIR-LadleDeslag will assist you in solving your problem.

 

Minimise Process Variations

Carryover slag variations in ladles are often the cause of a number of problems detrimental to processing and product quality. Unforeseen reoxidation reduces alloying yields and refining efficiency forcing the operator to deviate from the standard processing and take additional processing steps. The added oxygen also contributes to the formation of non-metallic inclusions that lowers product quality.

 

Key Features:

  • Deslagging montoring – Keep track of how successful the deslagging was and how long it took to complete.
  • Deslagging control – Give the operator feedback during deslagging to obtain a consistent slag removal. Set desired deslagging rate and let LadleDeslag inform the operators when the result is sufficient.
  • Data mining – Gives the personnel access to a database of previous deslaggings. Search the database with a number of different search options, such as dates, charge number, route etc. Schedule automatic reports to be sent out on a regular basis to engineers or managers.

VISIR - FurnaceSafe

Furnace Breakout Prevention

VISIR-FurnaceSafe infrared monitoring of your furnace shell minimises the risk of liquid steel breakout and maximises your operational furnace availability while at the same time increasing safety.

     

 

Why use the VISIR-FurnaceSafe system?

The risk of a breakouts will always be present in steel making with equipment damage, personnel injuries and loss of production as the consequence.

VISIR-FurnaceSafe continuously monitors the furnace shell thermal status and trends temperatures covering over 100 000 measuring points.

The monitoring system automatically alerts you when detecting early signs of dangerous hot spots, helping you to handle the situation before it becomes a hazard.

VISIR-FurnaceSafe stores data in a measurement database, letting you create weekly reports and evaluate refractory performance.
