Abstract: A method to automatically quantify dendrite arm spacing in dendritic microstructures. Once a location of interest in a cast material specimen has been identified, the information contained in it is automatically analyzed to quantify dendrite cell size information that is subsequently converted into a quantified dendrite arm spacing through an empirical relationship or a theoretical relationship. In one form, the relationship between DCS and DAS is such that the DAS in dendritic structure of cast aluminum alloys may be automatically determined from the measurement of one or more of dendrite cell size and the actual volume fraction of the eutectic phases in the local casting microstructure. Non-equilibrium conditions may be accounted for in situations where a theoretical volume fraction of a eutectic phase of the alloy in equilibrium condition is appropriately modified.

Abstract: The present invention provides a method of high efficient slag scooping-up from liquid iron and a device for implementing said method. The two wings of slag rake mounted to the front end of cantilever descend side by side until beneath the surface of the liquid iron at a certain depth.

When gradually moving close to each other in the course of swing movement, they get put together and clamp the solid slag. Then, driven by the cantilever, the two slag rakes which clamp the sold slag are brought to ascend until above the surface at a certain height. Finally they leave the space over the ladle and discharge the slag. The deslagging rate can reach over 90%. It just takes less than 3 minutes for the whole process of slagging-off. Additionally, the iron carried away in the process of slagging-off could be greatly reduced. The iron loss rate can be strictly controlled within 0.1%.
