• Objective and consistent level measurements.• Increase safety for operators.• Measurement of slag level, matte level, blister&alloy level

and transition zones.• Temperature measurement is possible in chosen layer of the furnace.• Cross check mass balance calculations.• Improve the process control by knowing your levels at all times.

USER BENEFITS & ADVANTAGES

Fully automatic EMLI-FurnaceProfile system installed on a 6-in line furnace.

THE EMLI-FURNACEPROFILE SYSTEM allows process improvement through objective and consistent metal level measurement. By knowing the levels in your furnace at all times, variations in the process can be eliminated. Temperatures inside the furnaces can be measured in order to control heat loss.

EMLI-FurnaceProfile system improves safety as no manual dip pin measurement is needed. Lance mechanisms, speed and immersion times are all customised to fit the specific requirements. The system measures the difference in electrical conductivity between the different layers in the furnace. From these changes in electrical conductivity metal levels are calculated with high accuracy.

• Measure the metal level continuously.• Improve the process stability by following the correct signal

signature.• Save smelting time by knowing when to tap.• Save smelting time by minimising dip bar measurements.• Typically used with ISA and Aussmelt furnaces.• Control bath agitation.


THE EMLI-SMELTERLEVEL UNIT continuously measures and monitors the true metal level in smelters or furnaces in real-time. The system measures the metal level irrespective of metal type, amounts of slag on top of the metal or temper-ature.

Tracking the metal level inside the furnace is crucial for process efficiency, short-ening tap-to-tap times and controlling energy consumptions.

With sensors mounted behind the refractory bricks the system provides informa-tion to track metal levels during melting and tapping.

THE EMLI-TUNDISHLEVEL SYSTEM continuously monitors the true metal levels in the tundish or runner and provides outputs to control the flow to main tain desired operating levels without being affected by the presence of slag or pro-tection powder. This allows a precise metal level control ensuring a constant pressure head, minimised intermix areas and accurate draining pro cedures.

Typical benefits are more constant casting speeds, avoid slag in the moulds, higher production output and substantial yield increase due to proper and con-sistent draining control.

CONTINOUS TUNDISH AND RUNNER METAL LEVEL MEASUREMENT

EMLI-TundishLevel

• Continuous true metal level measurement.• Enable reduction in manpower.• Minimised intermixed area.• Allow consistent ferrostatic pressure in tundish.

MORE INFORMATION

The tundish is connected at the caster to precisely monitor the metal levels without being affected by slag amounts or powder.

The sensor is placed in the mould either by an automatic manipulator or a manual arm.

THE EMLI-MOULDLEVEL SUSPENDED SYSTEM constantly monitors metal level in the mould or runner during casting and provides outputs to control the flow to maintain desired operating levels.

To position the sensor in the mould, an automatic manipulator or a manual arm can be used.

The electromagnetic technology means that the EMLI-MouldLevel Suspended system measures true metal level irrespectively of the amount of powder or slag on the metal surface.

ELECTROMAGNETIC MOULD LEVEL MEASUREMENT

VISION ANDINFRARED

The system allows a clear view of the skim-ming operations and an objective rating of the results.

THE VISIR-LADLEDESLAG SYSTEM is designed to monitor ladle deslagging op-erations in order to quantify the percentage of slag covered area. Thus, skim-ming operators using the VISIR-LadleDeslag system can produce slag free ladles consistently.

The system monitors the deslagging operations in real time.

By limiting process variations and ensuring that the deslagging process is more consistent the variations in quality in the final product are minimised.

The VISIR-LadleDeslag system automatically tracks and stores vital information for each heat and makes sure your quality assurance program is met.

LADLE SKIMMING MONITORING

Detect dangerous ladles before a breakout occurs. Make sure only safe ladles are taken to the caster.

THE RISK OF A LADLE BREAKOUT will always be present when handling liquid metals with equipment damage, personnel injuries and loss of production as a consequence.

Eliminate dangerous and costly situations by scanning and evaluating the con-dition of each ladle in your fleet.

Using the historical database, refractory performances can be objectively evalu-ated and average ladle refractory lifetime can be increased in a safe way.

Avoid metal losses during deslagging operations.

THE VISIR-METALDETECT SYSTEM is designed to monitor the ladle or furnace deslagging operations in real time to detect when metal is also being poured within the slag stream. Thus, a minimal amount of metal is lost and yield improved.

VISIR-MetalDetect system enables you to assist operators to control their metal losses in a safe and secure manner. By monitoring the deslagging stream and in-forming the operator when metal is detected the process can be modified quick-ly and safely.

By controlling the skimming process variations and ensuring that the metal losses are significantly reduced, yield improvements and quality consistency can be achieved.

All historical data is stored in an open and searchable metallurgical database.

METAL DETECTION DURING DESLAGGING

VISIR-MetalDetect

• Consistent and objective monitoring of metal losses during skimming.
