Oxygen Lance
Steel lance tubes made in various dimensions are used for blowing oxygen, carbon injection, dolomite or other additives into the arc furnace through the slag door and tall furnace. Oxygen blowing causes the oxidation of impurities, especially carbon in the melt, and their transfer to the slag, which enables their separation.
The lenses used in the steel industry are of various types. Calligraphy type These lenses, which are highly regarded in the steel industry, have 5 layers including the main steel layer, 2 layers of steel and 2 layers of refractory coating. The effect of these 4 layers on the steel layer makes the life of the Calriz lenses 3 to 10 times longer than the conventional lenses.
To enumerate the advantages of these pipes in oxygen steel making process are
The exothermic reaction and agitation promote decarbonisation and heat rise in the furnace, while foaming slag can be eliminated
Fusion of sub material can be accelerated
Quality of steel will be improved
As the process raises the temperature
Selection of raw materials to be charged becomes easy
The process raises the production capacity of an electric furnace
Hydrogen,Nitrogen and non-metallic inclusions can be eliminated through oxidation
It makes it possible to recover chrome with the use of high chrome steel scrap
To summarize Calorised & Ceramic Coated Pipe (CCCP) is carbon steel pipe with calorisation on outer surface of pipe, and thereafter multiple, thin layers of ceramic coating both exteriorly and interiorly. The outer surface of ceramic coating on pipe is resistant to slag attack and extends the life of the pipe when it is immersed into molten metal or in high temperature atmospheres. The CCCP applications include powder injections, tap-hole cleaning and opening nozzles is ladles, tundish and launders
