Toplotna prevodnost jekla za protibalistično zaščito SA 600 : diplomsko delo

Strašek, Blaž (author), Kosec, Borut (mentor), Bernetič, Jure (co-mentor)

jeklo za protibalistično zaščito z oznako SA 600 je rezultat uspešnega sodelovanja slovenskega podjetja SAAT d.o.o in švedskega proizvajalca specialnih vrst jekel Swebor Stal Svenska AB v povezavi s slovenskimi in tujimi institucijami znanja. Jekleno pločevino SA 600 odlikujejo dobre mehanske in izjemne protibalistične lastnosti tudi že pri majhnih debelinah, ki so natančno opredeljene ter podane s strani proizvajalca. Podatki o toplotnih lastnostih jekla SA 600 še niso bili na voljo, zato smo v okviru diplomskega dela določili in analizirali njegovo toplotno prevodnost, specifično toploto in temperaturno prevodnost. Izvedli smo meritve toplotnih lastnosti na sodobni vrhunski napravi za določevanje in analizo toplotnih lastnosti Hot Disk TPS 2200 v skladu s standardom ISO 22007-2 pri sobni temperaturi. Izmerjena toplotna prevodnost jekla SA 600 pri sobni temperaturi je 26,11 W/(mK), specifična toplota 3,70 MJ/(m3K), temperaturna prevodnost pa znaša 7,06 mm2/s.

• Title: Thermal conductivity of armour steel SA 600 : diploma thesis

Abstract

SA 600 armoured steel is a result of succsesfull cooperation slovenian company SAAT d.o.o and sweden special steel manufacturer Swebor Stal Svensk AB in connection with foreign and domestic knowledge institutions. Steel SA 600 is distinguished by its good mechanical propertie and outstanding armour properties even at small thicknesses. In diploma work we were determining heat properties of steel SA600, which is well known for its high strength and armour properties even at small thickness which are presented by the manufacturer. Heat properties are not determined by the manufacturer, so the purpouse of this work was to determine, measure and analyze the heat contuctivity, specific heat and thermal conductivit. For the measurments, we used Hot Disc TPS 2200, a moderen, high-end device for analysing heat properties. The measured heat conductivity of SA 600 steel at room temperature is 26,11 W/(mK), specific heat 3,70 MJ/(m3K) and temperature conductivity is 7,06 mm2/s.
