AOD Converter

The AOD Tuyere Pipe is a key refractory + metallic spare part used in the AOD (Argon Oxygen Decarburization) converter of a steel plant. 🔹 Function: Installed at the bottom side wall of the AOD vessel. Used for blowing oxygen, argon, or nitrogen into the molten metal during refining. Helps in decarburization, desulfurization, and homogenization of the melt. 🔹 Construction: Outer steel pipe with refractory lining (usually high alumina, zirconia, or magnesia-based). Inner bore designed to withstand thermal shock and erosion. Can be mono-block tuyere or multi-hole design depending on the steel grade requirement. 🔹 Features: High resistance to slag attack. Withstands high temperature pressure of oxygen/argon blowing. Long service life, reducing converter downtime.

Fabrication Engineering tuyeres have been designed for high-performance in your AOD vessel. Our patented calibrated design reduces the rapid increase in flow at a set shroud pressure as the tuyeres decrease in length with lining wear. The Fabrication Engineering tuyere will provide the same flow at full length as standard tuyeres but controls the rapid increase in ow after given pressure as the tuyere wears to provide more uniform shroud cooling gas flowdistribution in multiple tuyere vessels. A sturdy outer wall coupling piece provides rm support to lock the tuyere into the vessel shell. This heavy wall provides a good surface for a strong, secure connection between the tuyere and the vessel to help assure reliable inservice operation. The inner tube is swaged over a mandrel to provide a uniform diameter for metering the process gas. Swaging holds the diameter to very close tolerances ( 0.002 in or better) for the precise metering required to assure good process control and high-quality product. The outer tube is made from 304 stainless, providing high-temperature strength. The stainless steel tube is welded to the nut, which is threaded into the heavy wall coupling and seal welded for joint integrity. The assembly is mandrel sized to 0.002 in for precision shroud metering. When you choose Fabrication Engineering tuyeres, you are assured the design will be consistent with our latest developments in AOD process technology. Special designs are available to suit customers needs.

A.O.D. CONVERTER (Argon - Oxygen, Decarburization Converter)(i.e. Secondary Steel Making Unit for Stainless Steel Production). To meet the demand of high Quality Stainless Steel With Low Residues low oxygen Content the A.O.D. Converter (Secondary Steel Making Unit) are Mainly used. Majority of Stainless Steel Like Stainless Steel of utensil grade (S.S. -200- Series- 201,202) S.S. 300 Series (S.S. 304, 304 L , S.S. 400- Series (S.S. 410, 430, 431), Cast Stainless Steel is Produced by A.O.D. Process in Major Steel Plants. Thermodynamically, the A.O.D. Process is stainless steel refining processes rely on the dilution principal which means that by reducing the partial pressure of carbon monoxide ( by dilution / stirring with argon ) the equilibrium can be shifted from chromium to carbon Oxidation. In A.O.D. Converter The liquid steel will be refined to desired chemical composition by addition of required alloys fluxed use of Various gases. The gases media such as Argon, Oxygen, Nitrogen Air of Calculated amount are injected thru Oxygen Tuyers Oxygen Top lance (Optional) as per requirement from beginning to final of process, to achieve a most favorable thermodynamic condition due to high mixing energy within an extremely equalizing period. Oxygen Tuyer usually consists of Two concentric Tubes. The Inner Tube Serving to supply oxygen Gas the outer one to supply a protective gas. Ours Stain less Steel refining convertor (Equivalent to A.O.D. Converter) are designedSuitable for production of all grades of stainless steel, High low Alloy Carbon steel.Gas Mixing Station is electrically push button panel operated microprocessor based, which Promotes decarburization reduction equally good.Higher recovery of alloying element. Like chromium Manganese.Lower Gases non - Metallic inclusions in finished liquid metal.
