- REPAIR - FABRICATION - DESIGN - MODIFICATION
HOLDERS are the most common
failure point of your secondary power system. Located at a critical
point in the electrical circuit, electrode contact components are
subject to elevated temperatures caused by radiant heat, direct
flame and current resistance. Failures are generally caused by contact
surface arc damage or cooling system discontinuities.
Cast Copper Electrode
Holder Traditional in design, this
electrode holder is made from electrolytic cast copper.
The cooling system is provided by a cast-in cooling coil.
The clamping lever and shoe design are common for this style
equipment. Copper castings are reliable, repairable and
have a good track record for furnace life provided the cooling
pipe is schedule 80 Monel 400 or equivalent.
Holder For conventional EAF designs, when equipment
replacement is warranted, this design is favorable due to
its superior cooling system and higher electrical conductivity.
It is also cost-effective because it incorporates the otherwise
scrap back-section of your existing equipment into the design.
Fabricated electrode holders are repairable and last up
to 16 -18 years in normal furnace conditions.
Rings And Electrode Cooling Rings Dust
eliminator rings provide an automatic way to blow
off the dirt from the top of your
electrode heads prior to and throughout the electrode slipping
process. Thus no additional dirt wedges itself between
electrode and copper contact surface. The result is prolonged
furnace life for your equipment. Electrode cooling
spray your electrodes with water and keep them running
cooler thus saving you money. Both types of auxiliary
can be fabricated and installed on new or repaired holders.
