..., as in all subsequent steelmaking processes, is the oxidation and removal of carbon and other elements such as the high contents of silicon, manganese, and phosphorus in pig iron (hot metal) and scrap charges to produce liquid steel of the proper composition. Carbon is removed as CO gas, and oxides...

... . For example, the Chromel-Alumel thermocouple is a type K thermocouple. One of the problems with using thermocouples in hot furnaces is that the metal thermocouple wires will oxidize. If the oxide films extend too far below the surface, the thermocouple will no longer operate correctly. Oxidation rates...
