The thermal calculation of a induction furnace

Tato prce se zabv indukÄn­mi za­zen­mi, konkr©tnÄ tepelnmi vpoÄty indukÄn­ch za­zen­. Skld se ze t­ Äst­. V prvn­ Ästi jsou rozebrny zkladn­ pojmy indukÄn­ho ohevu a teoretick© znalosti sd­len­ tepla nutn© k pochopen­ problematiky indukÄn­ho ohevu. V druh© Ästi je uvedeno rozdÄlen­ a struÄn popis principu indukÄn­ch za­zen­. Byla zde vybrna a dkladnÄ popsna indukÄn­ kel­mkov pec pro samotn tepeln vpoÄet indukÄn­ho za­zen­. V posledn­ Ästi je teoreticky zpracovn postup tepeln©ho vpoÄtu nejpou­vanÄj­ch indukÄn­ch za­zen­, tedy kanlkov© pece, proh­vac­ho indukÄn­ho za­zen­ a kel­mkov© indukÄn­ pece, kter je nslednÄ porovnna s pedchzej­c­mi indukÄn­mi za­zen­mi z hlediska tepeln©ho vpoÄtu. Pro indukÄn­ kel­mkovou pec je zvÄrem poÄ­tn Ä­seln tepeln vpoÄet.This work deals with induction devices, in particular temperature computations of induction devices. The thesis is divided into three parts. In the first part, we give basic definitions of inductive warming and theoretical know ledge of heat induction that are needed to understand the problem of inductive warming. In the second part, we describe the principle of induction devices. We focused on crucible furnace which is described in details. We used this device for thermal computation of induction device. In the last part, we theoretically describe procedure of thermal computation of the most used induction devices, i.e., canal furnace, diathermy induction device, and crucible furnace; the last one is compared with the rest of induction devices from the computation point of view. For the induction crucible furnace, we provide numeric thermal computation at the end.
