The article presents an approach to the development of mathematical models non-sinusoidal and dual-frequency power supply for a linear induction MHD machine metallurgical purposes. issues construction numerical modeling modes three-phase inductor liquid aluminum stirrer are considered. Reduction losses is ensured by use toothless design inductor. absence steel teeth reduces saturation magnetic ...

This paper presents a practical application of fuzzy logic to the temperature control of glass melting furnace for television picture tube. Because of the complexity and nonlinearity, temperature control of glass melting furnace is still delegated to human operators. Though the overall characteristics of glass melting furnace are complex and nonlinear, one part of the furnace characteristics ca...

Introduction Fast, efficient batch melting using the modern induction furnace can improve operating flexibility and production yield, as well as reduce the cost of environmental protection. The compelling advantages of induction batch melting have encouraged foundries to change the way they handle their melting operations. Among the chief advantages is cost. The operational cost of a typical in...

In this manuscript, we consider the accuracy of end-point carbon content prediction affected by oxygen injection in multiple stages electric arc furnace (EAF) melting process. Such a would help to further evaluate process control strategies and optimize overall operation furnace. Principal component analysis (PCA) was used normalize 13 input variables affecting endpoint content. log-sigmoid tan...

A coupled reactor/furnace simulation has been conducted for a 100 kt/a SL-II naphtha cracking furnace containing both long-flame and radiation burners. The computational fluid dynamics approach was used to simulate the flow, combustion and radiative heat transfer in the furnace. The software packages COILSIM1D and SimCO were used to account for the cracking process in the reactor coils. The sim...

The aim of our research was to indicate the suitability metallurgical slags (two blast furnace and one steel slag) as components Cu-free friction materials. base mixture consisted nine including phenolic resin, graphite, tin sulphide, aramid fibers, iron powder, a barite with calcite, vermiculite. To this mixture, particle size below 0.1 mm were added individually in amount 20 wt.%. A alumina w...
