LOTZ Cutting more efficiently

November 04, 2016

LOTZ has proudly taken the lead in caster flame cutting technology once again. During a cutting test conducted at the ArcelorMittal slab caster LOTZ´ post mixing cutting nozzle OCH 35 has successfully proven to create a smaller kerf (see picture, kerf on the left) than the post mixing nozzle used before (kerf on the right). This results in a smaller cutting burr, also on the upper side of the slab, clearly to be noticed on the picture. The improved cutting results are due to the different nozzle design of the LOTZ nozzle.

At the same time the LOTZ cutting nozzle is consuming considerably less heating oxygen. The nozzle is compatible with the most used cutting torches of the SB 500 series.
