Fig 1 Porous plug assembly and different types of porous plugs Ladle furnace A ladle furnace is used to relieve the primary process of steelmaking of several of the secondary refining operations It is one of the key components of ladle metallurgy processes Sound ladle furnace operation delivers benefits in terms of steel quality productivity and cost efficiency
The present invention relates to a process for producing steel in a ladle furnace in which the molten steel is stirred by injection of an inert gas in the lower part of the furnace According to the invention the stirring of the bath of steel is effected by the injection of gaseous argon so as to distribute in a homogeneous manner the additives added and the metal temperature in the
The ladle furnace is a container used to hold molten steel for refining and pouring It consists of three parts the outer shell the inner lining and the casting flow control mechanism it can realize intelligent identification and determination of melting damage defects in the ladle lining and Model training for ladles Combined with the
LADLE FURNACE LF Primary functions of LF 1 Reheating of liquid steel through electric power conducted by graphite electrodes 2 Homogenization of steel temperature and chemistry through inert gas stirring 3 Formation of a slag layer that protects refractory from arc damage concentrates and transfers heat to the liquid steel trap inclusions and metal
1 LF Ladle Furnace Steelmaking Process LF Ladle furnace steelmaking process is to put the molten steel in the final stage of oxidation in the converter or electric furnace pour it into the LF furnace remove 50 90% of the oxidized slag and add
LF Ladle Furnace refining plays an important role during secondary metallurgic process The traditional LF refining operation relies on the workers experience it is disadvantageous to ensure
Ladle furnace slag is a useful by product for the improvement of natural clayey soils Mixtures of soil with LFS have volumetric stability and good bearing capacity The curing time of LFS soil mixes is longer than that of ordinary lime soil mixes The durability of LFS soil mixes is better than that of ordinary lime soil mixes
In this paper an interval type 2 radial basis function neural network system is presented that produces an accurate forecast of the temperature of liquid steel in a secondary metallurgical monitoring and control process The main goal of this proposal is to get the precise temperatures and times to aggregate the additives to the liquid bath to produce high strength
