In steel: Controlling temperature …can be achieved in a ladle furnace (LF). This is a small electric-arc furnace with an 8- to 25-megavolt-ampere transformer, three electrodes for arc heating, and the ladle acting as the furnace shell—as shown in A in the figure.
3. DEVELOPMENT OF LADLE REFINING FURNACE AT ELECTROTHERM Electrotherm, a leading manufacturer of MF induction furnaces, committed themselves to develop a small capacity ladle refining furnace. For small heats, three-electrode AC-arc LRFs are not successful because of high refractory erosion in the area adjacent to electrodes.
Ladle Furnaces, Induction stirring, Gas stirring, Clean steel. INTRODUCTION The choice of stirring method to be used in ladle metallurgy, in particular ladle furnaces (LF) will determine the operational and metallurgical characteristics of the equipment. The two major stirring methods, induction and gas, have complementary characteristics and
Bob Williams; The Electric Arc Furnace and Secondary Metallurgy Operations Handbook. Something I have been compiling over the past few years to help operators overcome any problems they may have in the day to day running and operation of the EAF and primarily the ladle furnace in secondary metallurgy.
CVS - SECONDARY METALLURGY LF Design Advantageous The Ladle Furnace is conceived for reheating the steel in the ladle placed on a ladle car and will be designed and built according to the most modern techniques in the field and will be in particular provided with: Water-cooled secondary circuit and water cooled flexible cables Water-cooled ...
Steel - Ladle metallurgy: The carrying out of metallurgical reactions in the ladle is a common practice in practically all steelmaking shops, because it is cost-efficient to operate the primary furnace as a high-speed melter and to adjust the final chemical composition and temperature of the steel after tapping.

Figure 23.2 : Ladle furnace showing arrangement of electrodes and porous plug Figure 23.2 shows ladle arc furnace where a cover equipped with three graphite electrodes are shown. The ladle bottom has a porous refractory plug for argon stirring. The ladle furnace is equipped with a …
Ladle refining of liquid metal is a proven technology to produce high quality steel. A Ladle Refining Furnace is used to raise the temperature and adjust the chemical composition of molten metal.
Secondary Refining For purposes of this article, Secondary Refining or Secondary Metallurgy is defined as any post steelmaking process performed at a separate station prior to casting and hot metal desulfurizaion. It does not include normal alloying prac tice in the furnace or at the ladle during tapping.
slag is in relationship to the basic refractory utilized in furnace and ladle vessels. If the slag is more acid it will erode the bricks, if it is more basic it will protect the bricks.
Ladle Metallurgy: Equipment. Principle of operation of the R-H process Adapted from: "The Making, Shaping, and Treating of Steel", 10th edition American Association of Iron and Steel Engineers, 1985, p. 680. ... Ladle refining furnaces can also use induction heating, and R&D is underway on gas heating. ...
In metallurgy, a ladle is a vessel used to transport and pour out molten metals. Ladles are often used in foundries and range in size from small hand carried vessels that resemble a kitchen ladle and hold 20 kilograms (44 lb) to large steelmill ladles that hold up to 300 tonnes (330 tons).
I. LADLE METALLURGY • DESULPHURISERS A vast range of products for fast and efective desulphurisation of steel in Ladle Furnace secondary metallurgy. Our products are multifunctional compromising many parallel actions in one step, enriched with metallic Aluminium to reduce the Oxygen activity in the slag-metal interface and also enriched with ...

Ladle Metallurgy. After tapping of steel from a primary steelmaking furnace such as BOF, EAF or EOF, molten steel for high quality or specialty applications is subjected to further refining in a number of alternative processes collectively known as ladle metallurgy.
Ladle Metallurgy Facility. The LMF's function is to refine the steel chemistry and maintain temperature. The LMF also acts as a buffer or holding area between the melt shop and caster. Ladle arrival at the caster must be closely synchronized with the process. The ladle …
ABB Metallurgy Products in Sweden has been committed to the development of new electromagnetic products for the improvement of steel cleanliness for more than 70 years. The first electromagnetic stirrer for ladle furnaces stirring (LF-EMS) was developed in 1965 and installed on a 30 ton ladle furnace at Ovako Steel AB in Sweden. More than 142
