Apr 23, 2014 · During ladle processing, the liquid steel is normally stirred by an inert gas such as argon through a porous plug(s) at the bottom and / or a lance inserted deep into the liquid steel from the top of the ladle.

Nov 20, 2019 · Cleanliness is affected when oxygen is picked up from the lining. Linings containing SiO2 in uncombined forms can contribute to deteriorating steel cleanliness. The basic design of the steel ladles comprises of the top lip ring, slag line, safety wall and bottom, barrel, working wall/bottom.

In the steel industry, ladles were ini- tially designed for storing, trans-porting and teeming liquid steel. With advancements in steel refin-ing techniques, it became necessary to conduct additional metallurgi-cal treatments in the ladle.

Jan 6, 2020 · Flow structures of liquid steel during stirring operations with argon injection in a ladle are studied using physical and mathematical models. Emphasis is made on the turbulent conditions near the metal-slag interface since this region is important for mass transfer and capture of inclusions by the slag phase.

done, the liquid steel is poured into the ladle. This pouring of liquid steel is called tapping. The ladle comes from the preheating station or it may come directly from the maintenance station depending on the empty period of the ladle. The temperature of …

Jan 5, 2012 · Ladle metallurgy is a process associated with clean steel-making process, wherein the process follows after the steel from converter or electric arc furnace (EAF), which may involve deoxidation, decarburization, and fine chemical adjustment of fine alloying elements or even the gases in the steel.

Oct 14, 2024 · The ladle furnace is a key element in steel production. You use it to refine liquid steel tapped from the main melting unit, like an electric arc furnace (EAF) or basic oxygen furnace. It monitors and ensures the temperature, chemical composition, and overall quality of …

Nov 8, 2014 · Steel Teeming Ladle and its Refractory Lining. Steel teeming ladle (STL) is needed in a steel plant to contain and transport liquid steel from the steel making furnace to the casting facility.

Two dynamic models were developed to predict the heat transfer and fluid flow in a preheating and teeming ladle. The gathered thermal conductivity values for ladle slag were used to study the effect of the slag layer on the top surface of the melt on …

Reduce or fully avoid smoke and emissions during preheating of Magnesia-Carbon and Alumina-Magnesia-Carbon lined ladles. More than 800 customers from the steel and foundry industries in over 60 countries worldwide rely on RHI Magnesita as a …
