The Institute of Materials 1996. XIV, 331 p. ISBN 978 1 906540 97 5. Gives engineers, research scientists and graduate students a clear understanding of the operation and control of the pyrometallurgical process. It will also be useful for technical training courses given to steel plant engineers...
Casthouse operations form a substantial part as this is an area where the molten metal is directed from the blast furnace to the torpedo ladle cars. For lowcost Blast Furnace (BF) operations, a good and troublefree cast house is important.

A promising type of steel slag for applications is the ladle furnace (LF) slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or .
Ladle Arc Furnace 3D interactive model. The operation executed at the ladle furnace is an essential part of the secondary metallurgy treatment, such as refining, adjustment of liquid steel temperature and chemical composition with the target to increase quality of steel. Argon bubbling is applied to homogenise the steel composition and temperature.
Refining is a stage of the secondary steel making process which is also referred as ladle metallurgy. The secondary metallurgy concept forced the reorganization of the technological flux. In this way, between primary steel making and steel casting in Continuous Casting Machine, a series of specific

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.
reoxidation between slag and steel during ladle reﬁning is necessary in order to optimise secondary reﬁning operations and thus be able to produce highly clean steels. In order to produce clean steels, the dissolved oxygen content is lowered by a reaction with a strong deoxidiser such as aluminium. In this reaction, alumina inclusions are formed.
Ladle Metallurgy Stations (LMS) play a crucial role in ensuring the quality of steel products. There is significant understanding of key aspects of both the chemistry and physics of the ladle process but this understanding has not translated into the development of sophisticated control systems.
Ladle Furnaces. The main purpose of the LF is to raise steel temperature and to control the chemical composition between tapping and casting, removing and/or modifying inclusions and acting as a buffer in melt shop logistics. Many different solutions have been developed, such as: LF with inert roof, supported on one side only for optimal...

Ladle Furnace Temperature Prediction Model Based on Largescale Data With Random Forest ... is changing continually during the ladle furnace metallurgy process. Therefore, it is hard to calculate the heat loss from the top surface exactly using the traditional mechanism model. ... A tree is grown on the new training set using the random ...
In this way, the ladle furnace increases the efficiency of the ladle metallurgy and reduces operating costs. The ladle furnace can also handle fine alloying work and injection processes, which previously took place in the conditioning stands.
Secondary metallurgy. Ladle Furnaces A ladle furnace is composed by a threeelectrode electric system, operating AC mode; working into a threephase electrical circuit, usually placed on the vertices of an equilateral triangle in around the furnace.
Jul 12, 2016· Ladle to ingot mould degassing – Preheated ingot mould with hot top is placed in vacuum chamber. Above the chamber a tundish is placed. Liquid steel tapped in the ladle is at superheat equivalent of 30 deg C. The ladle is placed above the tundish. Bottom pouring of liquid steel is into the tundish is desirable.

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 director an indirectsuction watercooled roof (controlled atmosphere), as well as
