from the primary melting furnace and solidification in the continuous casting or ingot mould. Today, most of the melt treatment steps involved are essentially carried out in the ladle, which has thus changed from a simple transfer or pouring means to a metallurgical treatment vessel. As a result, 'ladle metallurgy' has evolved into a fixed term.
Some of the literature reported work includes roasting of Cu–Ni concentrates, desulfurization process in steelmaking, primary smelting reactor for copper production, sequestration of CO 2 by steelmaking slag and ladle metallurgy operation [3,4,5,6,7]. In this paper, examples on modeling of blast furnace, BOF steelmaking and ladle metallurgy ...
Secondary Metallurgy Basic, acid, and neutral slags and refractories will be introduced, along with reasons for using each. The interaction of refractories and slags with metal will be explored, including methods of reducing refractory wear and quality improvements. The use of ladle metallurgy treatment and furnaces will be explained.
LF The Ladle Furnace (LF) is the fundamental secondary metallurgy solution for improved productivity, ˜exibility and uality. Tenova Ladle Furnaces are usually designed to increase the melt temperature up to 5°C/min. They are euipped with either a direct-or an indirect-suction water-cooled roof (controlled atmosphere), as well as
CVS MAKINA - LF TRAINING - D.E. 21 Basic Metallurgy BACKGROUND The reasons for preventing the primary furnace slag from entering the ladle furnace are : • minimizing the phosphorus reversion into the steel • minimizing the amount of oxygen entering the ladle. CVS MAKINA - LF TRAINING - D.E. 22 11.
ArcSave® is a new generation of electromagnetic stirrer (EMS) from ABB for electric arc furnace (EAF) operation which improves safety, increases productivity and reduces cost. This paper summarizes the results obtained from the first ArcSave® installation on a 90 ton EBT arc furnace at Steel Dynamics, Inc. (SDI), Roanoke, VA USA. White paper.

The principle of desulphurization is to transfer the sulfur dissolved in the liquid steel to a CaO-rich slag phase. This process is typically carried out in a ladle furnace (LF). For this process to be successful, two conditions need to be fulfilled: The slag must be fully liquid (liquid fraction > …

Optimized Lining for Ladle Metallurgy The areas subjected to low wear and those to extreme wear in the ladle, such as the slag zone, purging or impact area, should have a comparable residual thickness at the end of a ladle campagin in order to utilize the lining in the best possible way. This is accomplished by a suited combination of refractory
ladle furnace with a 56-MVA transformer, a 370-t duplex RH-TOP plant, a ladle treatment station (LTS) and various auxiliary equipment such as the steam generator and dedusting system. Special about the ladle furnace treatment is its focus on extreme reduction of sulfur in …

A general construction of a typical ladle of 3.2 m height and 3.5 m diameter is shown in Fig.2.1 [8] Fig.2.1. Constructional details of a typical ladle [8] The ladle structure is multilayered because of the fact that a ladle should be strong and heat insulated. The inner face of the ladle is built from specialized refractory bricks.

The recirculating degasser, CAS-OB and ladle arc furnace are all situated above their own tracks, such that the ladle can be positioned beneath them on a transporter car. A crane is required to lift the ladle between the cars. The tank degasser is accessed by lowering the ladle directly by crane 1.
types: primary or basic oxygen furnace (BOF) steel-making and secondary steel-making or ladle refining process. Primary steel-making is concerned with converting molten pig iron to steel from a blast furnace and steel morsel into steel through the basic oxygen furnace (BOF) and electric arc furnace (EAF) [11].
12.5.1.3.3 Ladle Metallurgy Emission sources in the ladle metallurgy process include the ladle furnace and the ladle heater. At some facilities, a roof canopy hood or a side draft hood is used to capture the emissions, which are then vented to a baghouse (which may be the same baghouse used for EAF emissions). 12.5.1.3.4 Casting and Finishing
