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

12.5.1.2.3 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). 12.5.1.2.4 Casting and Finishing

Physical System — The ladle system simulated in this paper is shown in Figure 2. The ladle inner diameter is 2.85 m, the melt height is 2.80 m and the initial slag layer thickness is 0.10 m. Different positions of the porous plug have been studied. Control of Gas Bubbles and Slag Layer in a Ladle Furnace by Electromagnetic Stirring
electric furnace shop producing high-alloy steel grades. In this case, the secondary metallurgy stage is completed at two stands, the first of which works as a traditional ladle furnace, and the second is a vacuum chamber. Both at the first and the second stage, the metal bath is blown with argon.
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.

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 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 > …
