Abstract

A Empresa EBDS Engineering colocou no mercado no ano de 2007 um novo sistema de detecção de perfurações (breakout), totalmente diferente do que pode ser encontrado hoje no mercado. O sistema chamado “Martine” tem sido desenvolvido e aperfeiçoado nos últimos 10 anos e vem sendo instalado em vários lingotamentos contínuos na Europa. Atualmente, a EBDS Engineering está promovendo este sistema mundialmente. O sistema de detecção de perfurações “Martine” é baseado em dois eixos: uma imagem termográfica do molde, e um avançado sistema de cálculo. A imagem representa as quatro faces de cobre do molde. Ela exibe em tempo real todos os eventos térmicos da placa recém formada “no interior do molde”, de maneira a revelar eficientemente qualquer evento irregular ao operador. Por exemplo, no caso de perfuração por colamento (sticking), a conhecida forma em “V” irá aparecer. Os cálculos são baseados nos possíveis comportamentos metalúrgicos das curvas. Isto permite detectar não só os colamentos, como também outros fenômenos. O sistema é “auto ajustável” às condições de lingotamento, de maneira que não se faz necessária a pré-seleção do tipo de aço. Dependendo do comportamento da máquina de lingotamento do cliente, novos algoritmos podem ser implementados para que o sistema se ajuste perfeitamente ao comportamento global das trocas térmicas. Resultados obtidos em máquinas de lingotamento contínuo na Europa apresentaram significativa superioridade em relação aos bem conhecidos sistemas clássicos.

 

The EBDS Engineering company has put on the market in the year 2007 a new breakout detection system, which is quite different than what can be found on the market. The system, called “Martine” has been developed and improved during the last 10 years and has been installed in several continuous caster in Europe. Today, EBDS Engineering is now promoting this system worldwide. The “Martine” breakout detection system is based on 2 axis: a thermographical image of the mould, and a quite advanced calculation system. The image represents the four copper faces of the mould. It displays in real-time all thermal events of the « in the mould » newly formed slab, so that every abnormal event is revealed efficiently to the operator. For example, in the case of a sticker breakout, the well known « V »shape will appear. The calculations are based on the possible metallurgical behaviors of the curves. This allows to detects stickers, but also other phenomenas. The system is « auto-adapting » itself to the casting conditions, so that no steelgrade have to be preselected. Depending of the customer's caster behavior, new algorithms can be implemented to fit perfectly the global behavior of the thermal exchanges. Results on European casters are showing significant superiority versus classical well-known system.
