The water-cooled composite conductive cross arm is a key component in metallurgical equipment such as electric arc furnaces. It combines conductivity, structural strength and efficient cooling functions, and is mainly used to support electrodes and transmit large currents. The conductive cross arm is welded with copper-steel composite plates. The outer copper plate is responsible for conductivity (using the high conductivity of copper), and the inner steel plate provides mechanical support (bearing the force generated by the movement of the electrode) The interior of the cross arm is designed as a hollow box structure with a built-in water cooling channel. Cooling water (or water-ethylene glycol mixture) is introduced to reduce the working temperature and prevent overheating.SR Conductive Cross Arm

Ferroalloy Refining Furnace
Ferroalloy refining furnace is the main equipment for smelting ferroalloy. Ferroalloy electric furnaces are divided into two categories: reduction electric furnaces and refining electric furnaces.
Reduction electric furnace, also known as submerged arc electric furnace or submerged arc electric furnace, adopts a submerged arc operation in which electrodes are inserted into the charge. The reduction electric furnace has open, closed (or semi-closed), and the furnace body has various forms such as fixed and rotating.
Refining electric furnace is used for refining medium carbon, low carbon and micro carbon iron alloys. The capacity of electric furnaces is generally 1,500 to 6,000 kilovolt amperes, and they adopt open fixed or covered tilting forms.
Ferroalloy Refining Furnace Application
Ferroalloy refining furnaces are mainly used to desiliconize and refine ores, high-silicon and low-carbon ferroalloy re-refined products and fluxes to obtain medium-carbon, low-carbon and micro-carbon ferroalloy products. Electric arc smelting furnaces are generally used;
Currently used for the smelting of medium chromium, low chromium, low microchromium, medium and low carbon ferromanganese, metallic manganese, ferrotungsten, ferronickel, ferrosilicon, high titanium slag, rare earth alloys, zirconium and other ferroalloy products;
It is also an important equipment for the later product refining of ferroalloy ore furnaces. Its production process is characterized by intermittent periodic charging and unloading operations.

Ferroalloy Refining Furnace Features
- The electric furnace can use a fixed furnace body, a tilting furnace body or a rotating furnace body;
- Depending on the smelting quality, water-cooled wall-mounted slag can be used;
- Use conductive cross arm or electrode holder for power supply;
- Electrical control can adopt PLC automation control technology;
- Furnace top feeding, PLC automatic control, and load cell weighing can be used to achieve high batching accuracy;
- The secondary busbar uses water-cooled copper tubes and large-section water-cooled cables, which can effectively reduce the impedance of the current system.
- The main structure is similar to that of an electric arc furnace. It has the functions of arc heating, furnace shaking and stirring, iron tapping in the tap trough and charging on the top of the furnace. Users can choose to make it according to the type of smelting alloy and the process.
