Adjustable length oxygen jet safely and efficiently near the steel bath

The Protect Block is a pure copper block with the purpose of promoting a reduction of the distance between burner/injector and liquid bath in an electric arc furnace, for an effective increase in the oxygen penetration into the liquid bath aimed at reducing the refining time and oxygen consumption.

For the Protect Block to resist the extreme exposure to which it is subjected, such as high temperatures, flame rebounds and scrap impacts during the early melt-in of the furnace charge, it was necessary to combine modern engineering in heat transfer and material quality, as well as special coatings to resist all the effects of the furnace environment.

The engineering applied to the Protect Block provides it with considerable service lifetime potential, less maintenance, less.
