Heavy-duty cutting torch for manual flame gouging
Cast-iron molds for making steel ingots are prone to the formation of voids, fractures and other flaws at their inner surface which may complicate the ingots’ removal from the mold. The only manufacturer of special gas-flame equipment for metallurgy works in Ukraine “Donmet” plant produces a special cutting torche for cast-iron mold scarfing. It has proven itself at such enterprises as PJSC “Azovstal Iron and Steel Works”, PJSC “Mariupol Integrated Iron and Steel Works named after Ilych”, JSC “Zaporozhsteel”, etc.
Design features: single-block nozzle with a pressed antiwear bush; in-nozzle gas mixing ensuring operational safety.
Used gas fuel: natural gas (methane).
Purposed for: elimination of flaws at the cast-iron mold inner surface; smelting of defects in grey-iron and steel castings; scarfing of low-carbon ingots, blooms and slabs.
We perform customization of the cutting torch to the individual conditions of production (length, head bending angle, etc.)!
