Sinoxx 4462 duplex and Sinoxx 4410 super duplex steels are steels manufactured by the largest Slovenian steel manufacturer SIJ ACRONI Ltd. They are stainless steels, which means that the mass fraction of chromium always exceeds 20% in their composition. They are distinguished by their dual (duplex) microstructure comprised at room temperature of body-centered cubic lattice (BCC) ferrite and face-centered cubic lattice (FCC) austenite.
This thesis is primarily concerned with analyzing and optimizing the temperature profile of steel heavy plattes and hight temperature furnace HTF on a heat treatment line HTL. Temperature profile was measured in an industrial enviroment containing a heat treatment line course of 50 mm duplex heavy plattes type S32205, Wr. Nr. 1.4462, EN X2CrNiMoN – 22 – 5 – 3 and 10 mm super duplex stainless steel heavy plates type S32750, Wr.Nr. 1.4410, EN X2CrNi – 22 – 5 – 3.
Experimental research on heat property identification machine Hot Disk TPS 2200 enabled measuring heat conductivity and specific heat as well as calculating the conductivity of mender quality and prime quality steels in accordance with ISO 22007-2.
