ELECTRODE VOLTAGE CLAMP

The Electrode heads and contact pads provide the final connection between the power supply and the graphite electrode. They are exposed to extreme mechanical conditions (vibration, torsion etc.) and thermal cycling and as a result are the weakest link in the secondary circuit. Traditional electrode holders are either cast or fabricated from copper plates. These furnace spare parts are smaller and incorporate only the electrode contact area. In traditional electrode holders, the electrode is pushed forward into the contact area. In the case of contact pads, the electrode is pulled back with steel housing equipment to make contact with the pad.

The current transfer between the contact pad and the electrode occurs in the lower 3 or 4 inches. Proper clamping of the two electrode voltage clamp for is a necessity in order to prevent arcing between the electrode and the contact area. Any dirt build-up in this area will result in resistance to current flow and will cause over-heating and damage to the electrode holder/contact pad. Typically cooling water requirements will vary from 2 to 40 gallons per minute depending on the electrode size, water quality, clamping force and maintenance of a clean contact area. The contact area of the 2 electrode voltage clamp should be cleaned regularly to remove oxidation, carbon build-up and other material build-up in this area.

STRENGTH

CHNZBTECH TWO ELECTRODE VOLTAGE CLAMP STRENGTH

The electrode clamping adopts a butterfly spring, which drives the 2 electrode voltage clamp to hold the electrode tightly. It is released pneumatically or hydraulically, with a high clamping force and reliable electrode clamping.

The two electrode voltage clamp electrophysiology adopts chromium copper alloy or copper steel composite plate, and the internal water cooling has a long service life. Ordering matters:

The conductive contact shoes made of T2 copper with good performance, forged and cold worked, can ensure good water cooling effect, improve conductivity, prevent arcing, and extend service life.

SPECIFICATIONS

TWO ELECTRODE VOLTAGE CLAMP SPECIFICATIONS

EAF two electrode voltage clamps contain a pipe/coil which is manufactured from either a monel or stainless steel pipe which is then cast into place. This cast-in water passage allows water to be in direct contact with the copper which provides maximum cooling efficiency and longer electrode holder life.

METHOD

TWO-ELECTRODE VOLTAGE CLAMPING METHOD

Main function of EAF 2 electrode voltage clamping is to firmly fix the electrode on the electrode bracket to ensure the stability of the electrode during the operation of the EAF. Hydraulic cylinder works with cup spring to release and contract clamping device so electrode could be controled base on EAF production requirement.
