    [2] 18/02/2021 - Dernière modification le 25/02/2021 Cowpers Un cowper moderne consiste en cylindre vertical en acier de 6 à 9 m de diamètre et s'élevant à 20 à 35 m. Cette enceinte est remplie de briques réfractaires dont la nature dépend de leur rôle : on a des briques isolantes qui protègent la face interne du blindage du cowper, et des briques stockant et restituant la chaleur. Ces dernières servent à la construction du puits de combustion, où se déploie la flamme, et du rûchage, un empilement de briques perforées qui absorbe la chaleur des fumées. Le puits est souvent intégré dans le cylindre où il occupe environ un tiers de la section du four. Les plus gros cowpers sont dotés de puits externes qui permettent de mieux isoler la zone de combustion de celle d’accumulation/restitution de chaleur. La chauffe étant plus lente que le refroidissement, chaque haut fourneau est doté de trois, parfois quatre, cowpers passant alternativement dans chaque phase. En fonctionnement continu, un cowper restitue sa chaleur pendant environ 30 min, avant que le vent soit orienté vers le cowper qui vient de finir une réchauffe de 50 min (durée à laquelle il faut ajouter les phases d'inertage et de mise en pression, qui durent 10 min). Un cowper moderne peut réchauffer environ 1,4 tonne de vent à 1 200 °C, par tonne de fonte. Lorsqu’il restitue sa chaleur, c'est donc, pour un haut fourneau produisant 6 000 t de fonte par jour, un four d'une puissance d'environ 100 MW. La chauffe est effectuée par combustion d'une partie du gaz produit par le haut fourneau, qui doit être mélangé avec un gaz riche pour atteindre les températures souhaitées. Source: Wikipedia Modern cowper consists in vertical steel cylinder 6 to 9 m and a diameter amounting to from 20 to 35 m. This enclosure is filled with refractory bricks whose nature depends on their role has insulating bricks that protect the inner face of the shield cowper, and storing and reproducing bricks heat. The latter are used in the construction of wells combustion, where the flame spreads, and rûchage, a stack of perforated bricks which absorbs heat of the fumes. The well is often integrated into the cylinder where it occupies about one third of the furnace section. The biggest feature cowpers outer wells to better isolate the combustion zone of the accumulator / heat delivery. Heating is slower than cooling, each blast furnace has three, sometimes four, stoves passing alternately in each phase. In continuous operation, cowper restores its heat for about 30 minutes before the wind is facing cowper who just finished a 50-minute heats (time at which there are the phases inerting and pressurization, lasting 10 min). Modern cowper can warm wind of about 1.4 tons to 1200 ° C, per ton of pig iron. When the heat returns, so this is for a blast furnace producing 6000 t of pig iron per day, a furnace with a capacity of approximately 100 MW. The heater is powered by combustion of part of the product through the furnace, which must be mixed with the rich gas to achieve the desired gas temperature.

    [3] 13/11/2012 - Dernière modification le 12/02/2021 JavaFX Bootstrap by Jim Weaver and Gerrit Grunwald Much of this session will draw upon the work in the Pro JavaFX 2 book that Jim Weaver co-authored, as well as the UI controls and gauges that Gerrit Grunwald created for the open source JFXtras project. Some of the areas that we'll cover are: Getting started with JavaFX Creating a user interface Using Scene Builder and FXML Using the JavaFX UI controls Creating custom UI controls Leveraging the strengths of JavaFX and HTML5 Overview of DataFX, calling web services Using Scenic View Using JavaFX APIs from Alternative JVM Languages Embedded Java/JavaFX on a Raspberry Pi Embedded Java/JavaFX on a BeagleBoard Wrap-up and additional Q&A During the session we'll have brief guest appearances by JavaFX developers such as Martin Gunnarson and Pär Sikö, Stephen Chin, Angela Caicedo, Jonathan Giles, Johan Vos, and Jasper Potts. We'll also be awarding ten copies of the Pro JavaFX 2 book to participative audience members. Source: Devoxx
