Cutting torch, especially for cutting off the semi-finished product in a system for continuous metal casting ».

The invention relates to a cutting torch for cutting off of the semi-finished products in a system for continuous metal casting «

At plants sub continuous metal casting is located the cutting torch near the nooh glowing semi-finished product and is exposed to considerable warming due to its thermal radiation · The nozzle on the Burner tip affected, which seriously jeopardizes the stability of the cutting edge Cutting torch can lead to an incomplete cut, so that Ais oil eating has to be interrupted «

The object of the invention is to ensure that the cutting torch works evenly and without interference incomplete cuts and disturbances in the casting process avoid »The invention is based on a cutting torch
