Oxygen flame cutting burner - esp. for cutting large, continuously cast steel billets

摘要

Oxygen flame cutting burner, where three pipes feed gases into three channels in the burner body. One channel leads to a first ring chamber feeding gas into a ring outlet nozzle. A second channel leads to a second ring chamber concentric with first chamber and feeding gas through an annular dosing slot into the outlet nozzle. The third channel runs along the axis of the burner body and heads to an inner nozzle located on the axis of the ring outlet nozzle. The tube may be located in the burner body to form the annular dosing slot; and both ring chambers may have conical profiles formed inserts in the body. Used to cut metal ingots, esp. very large steel billets, made in (semi) continuous casting plants.
