This paper concerns the mathematical modelling and numerical solution of thermoelectrical phenomena taking place in an axisymmetric induction heating furnace. We formulate the problem in a two-dimensional domain and propose a finite element method and an iterative algorithm for its numerical solution. We also provide a family of one-dimensional analytical solutions which are used to test the tw...

The design of system for operative planning of blast furnace production process in VSŽ inc. Kosice A system for operative planning of blast furnace production process is described in the paper. The suggested system is based on the use of a new hierarchy of operative plans, consisting of one-month plan, (7+3) days plan, and 24-hour plan. The system allows smoothing of production process at the b...

air cooled blast furnace slag is a by product made of gradually air cooled molten blast furnace slag, and is often stored in stockpiles near the iron mills and usually occupy a wide area around the iron mills. from this perspective the further use of these materials can have its own merits. air cooled blast furnace slag can be used in asphalt mixtures because of their proper frictional properti...

We compared a stabilized-temperature L'vov platform furnace containing an end-heated graphite atomizer (HGA) and transverse Zeeman background-correction system with a side-heated furnace system (transversely heated graphite atomizer; THGA) containing a longitudinal Zeeman background-correction system for the determination of aluminum in plasma and urine. The regression statistics for the correl...
