AOD Tuyeres

L-TEC tuyeres have been designed for high-performance in your AOD vessel. This patented design reduces the rapid increase in flow at a set shroud pressure as the tuyeres decrease in length with lining wear.

Features

  • The tuyere is designed to have the same flow at full length as the standard tuyeres but controls the rapid increase in flow after given pressure as the tuyere wears. This will provide more uniform shroud cooling gas flow distribution in multiple tuyere vessels.
  • A sturdy outer wall-coupling piece provides firm support for locking the tuyere into the vessel shell. The heavy wall provides a good surface for a strong, secure connection between the tuyere and the vessel to help assure reliable in-service operaton.
  • 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" or better) for the precise metering required to assure good process control and high quality product.
  • The outer tube is 321 stainless providing high temperature strength. The tube is stainless steel 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" for precision shroud metering.
  • To make it easier to order the correct tuyere for your vessel, the larger size tuyeres (sizes A, B, C, D and E) are all 26" long. This makes them suitable for the thickest typical refractory wall, and they can be trimmed to fit thinner walls. In addition to the stock sizes, other dimensions can be obtained on special order (minimum lead time on special orders is 90 days)
  • When you order L-TEC tuyeres, you are assured the design will be consistent with our latest developments in AOD process technology.
  • Special designs are made to suit customers needs.
