1. The product is welded with copper-steel composite plates to form an electrode conductive arm, in which the copper layer is used for electrical conduction, and the steel layer is used to support various mechanical forces.
2. There is a water interlayer in the electrode conductive arm frame, which is cooled by water and can withstand the burning of the water flame of the electric furnace.
3. The electrode clamping adopts a butterfly spring, which drives the hoop to hold the electrode tightly, and releases it pneumatically or hydraulically. The clamping force is large and the electrode clamping is reliable.
4. The electrode clip is made of chrome-copper alloy or copper-steel composite plate, and the internal water cooling has a long service life.

Order Items:

1. The orderer can choose to order according to the parameters in Table 2-1. If there are different requirements, please put them forward in the contract.
2. The order electrode arm is a part of the electric furnace or ladles furnace ferroalloy refining furnace. When ordering the electrode conductive arm, the user should also provide other related dimensions, such as

• The distance between the center of the electrode column and the center line of the furnace
• The connection form and related dimensions of the electrode arm and the electrode column
• Hydraulic medium and pressure or compressed air pressure, etc.
