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 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 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.
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 […]
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 […]
