Flame Scarfing Machine 009
Flame scarfing machine in use

The most up-to-date, high-capacity scarfing machine of its kind in the world.

The scarfing demonstrations have been a complete success, once again proving that unmatched performance data is the norm for this Evertz facility. The machine is operated manually.

Advantages include an optimal view of the torch and slab, and the immediate recognition and removal of defects during the scarfing process. The operator can react immediately.

Slabs of 90 t and above can be scarfed. We are constantly upgrading and improving our gas technology. In the case of upgrades and improvements, the retrofitting of machines with older gas systems is guaranteed. Current investigations include impulse scarfing. For brown fume (FeO) reduction we offer dedicated, proprietary technology.

Scarfing of slabs:

  • All-surface, narrow-face and selective scarfing at speeds between 8 and 25 m/min.
  • Scarfing widths from 100 mm to 450 mm
  • Water-cooled torches with customized designs ensure long service life
  • Fast ignition through iron-powder addition
  • Torch manipulation from right to left and immediately again from left to right guarantees up to twice the capacity with one-time ignition
  • Minimal ridge between the scarfing cuts. Scale-free surfaces thanks to a universal descaling system (proprietary process of Evertz Hydrotechnic)
  • Several selectable scarfing programs with the same torch, providing selection of the desired scarfing depth and other benefits

Scarfing times:

Scarfing one broad face of an approx. 45 t slab, having a length

of approx. 13 m, a width of 2000 mm and a thickness of 220 mm (= approx. 26 m2), takes approximately 6 minutes.

Capacities:

Depending on the desired width of the cut, capacities of more than 100.000 t per month are possible.
