Abstract

U radu je opisana električna komorna peć za toplinsku obradu i njezini dijelovi. Opisane su termodinamičke pojave prisutne kod zagrijavanja peći, sistematizirani su vatrostalni materijali za izradu peći i materijali za elektrootporne grijače. Objašnjen je izbor plinske zaštitne atmosfere u peći te načini mjerenja i regulacije temperature. U praktičnom djelu rada dimenzionirani su ključni elementi male električne peći bez zaštitne atmosfere. Razrađene su konstrukcijske varijante i predstavljen je CAD model peći snage 15 kW i volumena komore 88 L zajedno sa shemom spajanja grijača i regulatora temperature.

Abstract (english)

In this paper an electric chamber furnace for heat treatment is described along with its parts. Thermodynamic phenomenons linked to heating of furnace are explained and refractory materials for construction and electric heating element materials are systematised. The choice of atmosphere within the furnace is explained along with methods of measuring and regulating temperature within the furnace. In experimental part of the paper key elements of a small electric furnace without protecting atmosphere are dimensioned. Production options are considered, then CAD model of a 15 kW furnace with chamber volume of 88 L along with electric shematics for connecting the heating elements and temperature regulator is presented.
