LEAN and Mean?

LEAN and Mean?

LEAN production is a methodology dating back to the 1950ies but is yet not fully implemented in liquid metals processing despite the obvious advantages obtained in other industries. This is to us a mystery that needs to be resolved. Why do you as a manager hesitate to take your production several steps up the ladder of efficiency and product quality? There better be a good reason for this… Ok, we agree – liquid metals production is far from a car manufactoring production line. We acknowledge this but would also like to emphasize that the LEAN fundamental principles apply regardless. These are true in any type of production, you just need […]

Thermal Imaging in Metals Production

Thermal Imaging in Metals Production

  Do you feel that there might be something you have missed out on? What new technology have emerged out there, and what can it do to our production, processing, and product quality? What happens at our competitors production sites? Infrared imaging is maybe not a very new technology, but a technology just recently made accessible to most of us. Increased availability, robustness and more competitive prices have made this technology emerged as an interesting opportunity to measure or register events before maybe not even seen. The thermal imaging technology will make your production and processing more safe, more efficient, and enhance your product quality. This white paper presents the principals of thermal imaging […]

Ruukki Ladle Monitoring

Ruukki Ladle Monitoring

Read about how Ruukki monitors ladles in the ladle furnace operation to ensure a safe operation and avoid break-out. Metal break-out during procesing is a potentially dangerous event which occurs when least expected. The liquid metal penetrateing the ladle refractory and steel sheel will not only result in major ladle damages but in the worst case scenario loss of lives may occur. Even less dramatic events may be extremely costly in terms of damage equipments and loss of production tonnage. The Finnish steel producer Ruukki have decided to take safety first and monitor the ladle furnace operations to avoid dangerous situations. -“In our production personnel safety, production stability, and delivery accuracy […]

Slag Carry-Over – the Last Unknown?

Slag Carry-Over – the Last Unknown?

Slag carry-over in ladle refining operations is most likely one of the last unknowns in metals processing. No-one can for certain tell that the carry over amount is under control and does not influence on processing and product quality. We know for sure that the variation in sub-sequent processing operations due to uncontrolled slag carry-over is larger thn you would expect with very unfavorable consequences: Processing instability increases and targets are missed. Product quality suffer. This paper elaborates on the influence on processing, production, and product quality by slag carry-over in ladle refining operations. You will be surprised that something unknown and usually poorly controlled influences so strongly on your […]

Ladles – the Forgotten Process Area

Ladles – the Forgotten Process Area

Ladles in metals production is usually forgotten and just work – until they don’t. To avoid managing ladle handling and performance is a costly and risky strategy that could jeopardize your throughput and make your production costs skyrocket. Our perspective is that the ladles should be handled as any other process area – set your routines for handling and operations, register data and then follow-up and make improvements. In this paper we will discuss how to make this happen and make sure your ladle performance will never slow you down and make you miss your targets.

Stability is Everything

Stability is Everything

Have you checked out this week’s production report? What about those few hick-ups that you could have been without? Disturbances generate production instability – a state that is never of any good for your tonnage throughput, product quality or operator safety. On the following pages we will elaborate further on the importance of stability to be able to improve production further. We sort out the terms and definitions related and show how to obtain stability by a correct processing and production design. This is the second part in our white papers series on how to take the first step towards world’s class metals production. In the first part, “Get the Good […]

Get the Good Tonnes Out!

Get the Good Tonnes Out!

Are you a metal production manager? Are your experiencing that daily issues just matches what you can cope with? Do you have a unpleasent feeling that you slowly fall behind competitors? We understand that the pressure is on from all fronts to perform and there is little or no time to reflect on longer terms decisions. Having said that, we must also emphasize that in a longer run this approach will be detrimental to the production – eventually development work and strategies crumble and everything is handled on a daily basis without control. This is the worst of scenarios and a place you as a production manager do not want […]
