ELdFOS - Sep 11, 2013
ELdFOS PROCESS Electrotherm Refining Furnace with ELdFOS process is used for the following: De-phosphization of steel by as much as 50 points De-sulphurization of steel by as much as 50 points Removal of metallic inclusions to make clean steel Reduction of gas content by feeding Aluminium / CaSi wire to produce “killed”steel. Oxygen level of 30 ppm can be obtained Homogenization of temperature and composition of molten steel by gentle stirring Degassing treatment of steel to achieve low gas content (oxygen, nitrogen and hydrogen) Holding of molten steel while sustaining temperature / superheating for sequencing on the CCM
