Various metallurgical slags are generated in metal extraction, refining and alloying processes. Due to the large slag quantities and the strict erenvironmental regulations, recycling and utilization of these slags are an attractive alternative in order to reduce and eventually to eliminate the disposal cost, to minimize the related environmental pollution, and to save the resource conservation.The global warming effect and natural resource saving are the general environmental topics nowadays. In addition, the land...

In a large competitive environment in which today foundry exist are more important is production of castings with high quality and high economic efficiency. Therefore, the use of 3D software and simulation programs is necessary in the pre-production stages. In them it is possible to design, construct and simulate filling and solidification of castings in the foundry mould, design ingate system and feeder system. A properly designed and calculated ingate and feeder system is the first prerequisite for producing of ...

The manufacturing and processing of metals is connecting with large number of different types of wastes. One kind of these wastes are dusts and sludges which arise as a result of the melting processes or in the machining of castings. Flue dusts from melting processes are captured most often on filters, scrubbers or in Venturi scrubbers. Dust particles resulting from the machining of castings (grinding and blast cleaning) remain in the grinding rooms or they are sucked and collected on filters. Whereas these dusts ...

At present, increasingly high demands on the quality of the manufactured castings, which are used in the automotive industry. The foundry respect there are a number of advanced technologies, which are used for the casting. These include the technology of production castings by investment casting. It is used particularly where in view of the complex shape casting technology is the production of other more expensive, respectively, it is not at all possible. Such casting is the rotor of the turbocharger to be used in...
