The document outlines the organizational chart and production processes of an engineering steel plant. It details the roles of leadership positions like the president and directors. It maps the flow of raw materials from storage through melting, refining, alloying and pouring processes. Key stages include loading scrap and alloys, melting in electric arc furnaces, secondary refining using AOD converters, heating ladles, and final pouring of liquid steel. Laboratories analyze raw materials and samples to control quality.

9. SCRAP Types of scrap used in the manufacturing of steel: Scrap steel from stamping shop; Return (gates, fins, surplus steel); Ferroalloys; Auxiliary Materials

10. Specification of Raw Materials e Ferroalloys The chemical laboratory is the sector responsible for the identification and analysis of materials.

11. Arc and Electric Furnaces The Arc Furnaces enable two metallurgical stages to be carried out.

12. Stages in the Process Melting: Consists of raising the temperature of the metallic load until there is a complete transformation to the liquid phase, for this to happen the equipment has to supply enough energy. Boiling/Refining : In these two stages there is a reduction mainly in the content of C , Si, P, S, N e O.

13. Induction Furnace Melting Process by way of Magnetic Currents.

14. AOD ( Argon Oxygen Decarburization ) Converter The AOD process is a secondary refinement of liquid steel.

17. Pouring Transference of the liquid metal to the ladles happens after the preparation of the steel. Final deoxidization treatment occurs in the pouring ladles.
