OXYGEN STEEL MAKING (BOF)

 

 

Till today maximum crude steel produced via oxygen blowing converter route and this process route already established throughout the world. The rapid improvement of blowing technique (top & bottom) also achieved world recognition with the following advantages:

 

-          Improved target accuracy of chemical composition and temperature

-          Reduced tap-to-tap cycle time less than 35 mins

-          Less reblow of the melt

-          Increased metallic yield

-          Reduction Fe-content of converter slag

 

 

Today’s oxygen blowing steel plant consists of following bays:

 

-          Charging bay

-          BOF-Converter bay

-          Ladle bay

-          Casting bay

 

 

The programmable logic control system (PLC) is used to carry out direct process sequence via Level I and Level II operation to determine C-content, temperature and target analysis economically.

 

 

The main fabrication and supply of IGH for BOF converter are as follows:

 

-          Converter vessel

-          Trunnion ring with shafts

-          Trunnion bearings

-          Converter tilt drive unit

-          Oxygen top lance

-          Bottom blowing facilities

-          Flux and alloy addition system

-          Exhaust gas cooling and cleaning

INERT GAS OXYGEN CONVERTER (IOC)

 

 

The steel refining converter is a duplex or two stage process. The molten metal will be premelted in any premelting furnace and charged into a refractory lined converter. Exact calculated amount of process gas (Oxygen, Nitrogen and Argon) are blown through submerged tuyeres to achieve optimum thermodynamic and kinetic conditions to produce value added steel.
