Description

For operational safety during oxygen-lance cutting

Lance-holder purposed for: securing the lance and adjusting the oxygen feed flow while cutting. It is successfully used at PJSC “ArcelorMittal Kryviy Rih”, PJSC “Mariupol Integrated Iron and Steel Works named after Ilych”, CJSC “Donetsksteel Iron and Sreel Works”, etc.
“Donmet” plant has mastered mass production of lance-holders in three versions: with the cutting oxygen valve attached to the handle, without the valve and with a ball valve.
The delivery set contains spare parts for the lance tube mounting (8 to 21 mm in diameter – as per customer’s specification).
To replace the lance tube it is required to unscrew the fastener, remove the remaining stub of the tube from the lance-holder and insert a new tube, then tighten the fastener using sealing gaskets.

Oxygen-lance cutting is burning holes in the metal with a jet of oxygen that is fed through a steel tube (the lance). This method is used for cutting through thick materials including steel and grey iron, cutting anvil-blocks, scrap, topping of large-size ingates, etc. without the preheating flame. The cutting process is initiated by local heating of the metal and the tube end to the iron kindling temperature (1350°C – 1400°C) by an outside heat source (cutting torch, electric arc, etc.). The continuous cutting process is kept up due to the heat generated during the combustion of iron in the processed part and in the lance tube. Thus, the lance tube is an expendable material.
