• Do and responsible for the work process in the ladle furnace section, including :• Ladle preparation, This process begins with preparing the ladle that will be used to hold the molten metal. Ladles must be cleaned thoroughly before use to avoid contamination of the metal to be processed.• Heating ladle furncae, the heating process is carried out to maintain temperature drops, for example due to the addition of alloys or to regulate the temperature before casting begins. This process can be carried out using electrical energy transmitted by the electrode.• Temperature measurement in to the ladle, Measurements are carried out to determine the temperature that will be produced in the furnace and also ensure that the process that occurs will run as it should and also ensure that the chemical mixture or process can also match the temperature in the furnace.• Injection of additional ingredients, additional materials such as alloys or other modifying materials can be added to the ladle to modify the chemical composition of the molten metal according to requirements.• Homogenization Process, injecting Argon or Nitrogen gas to stir the liquid from under the ladle (bubbling) so that the composition becomes homogeneous• De-Oxidation process, this process is carried out to reduce oxygen gas by adding Al according to the target.• De-Sulfurization process, reducing the sulfur element (S) by using top slag, namely adding CaO and CaF2 or you can reduce the sulfur content in steel using the slag treatment method• Alloying Process, the addition of alloying materials is adjusted to the type of steel to be made.
