Abstract

Changes in Mechanical Properties of Holding Magnet Type LS50 in Liquid Metal Transfer Ladle Due to Repeated Use Sumiyanto1 , HarwanAhyadi2 ,Rudi Sapura3 , Djoko Suprijatmono4 {sumiyanto@istn.ac.id} Mechanical Engineering Study Program, National Institute of Science and Technology, South Jakarta Abstract Inside a ladle there is one component of the material that often gets damaged, namely the Holding Magnet Type LS50, which has corrosion (damage) on the surface due to temperatures that reaches 1500 °C with a time limit of 150 minutes. Test shows the material contained in the Holding Magnet Type LS50 are steel, copper (CuZn), and magnet. The Steel of Holding Magnet Type LS50 has a chemical composition with the main ingredient of iron (Fe) around 97.961% and other elements such as carbon, silicon, manganese, chromium and other alloy elements. As for the microstructure, CuZn has a microstructure in the form of an α (alpha) phase and a ß (betha) phase. The average of Holding Magnet hardness test results shows only CuZn experienced a very drastic decrease in the hardness value due to continuous heat exposure while the temperature for CuZn melting point is only 1084 ° C. Keywords: Chemical Composition, Metallography, Hardness. DOI: 10.7176/CMR/12-7-08 Publication date:October 31st 2020
