Measurement of Carbon in Ferrosilicon Alain Salaville, Jérôme Barraqué, Application Laboratory, Longjumeau, FRANCE Keywords: ferrosilicon, carbon, EMIA 820V 1 Introduction Ferrosilicon is added as a deoxidant and as a alloying element to steel, that require a special low carbon content. The low Carbon in Ferrosilicon decreases the electrical conductivity and magnetostriction of electrical steels. 2 Instrumentation 2.1 Principle The test was performed on the model EMIA 820V. The measurement principle is shown in Figure 2. The sample is placed in a ceramic crucible in a high frequency induction furnace. The sample is heated at a programmable temperature. Gases produced during the combustion are then ana- lyzed using four Infrared detectors, after dust and moisture removal. The analysis of
