- 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.
- 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.
- 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.
- The electrode clip is made of chrome-copper alloy or copper-steel composite plate, and the internal water cooling has a long service life.
- 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.
- 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.
