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

Ladle Refining Furnace (LF, VD, VOD)
The product series of ladle refining furnaces (LF, VD, VOD) are 20t~350t LF, VD, VOD, VHD, VC ladle refining furnaces and vacuum casting furnaces, which are mainly used in steel metallurgy, mechanical casting, new materials and other fields.
Ladle Refining Furnace (LF, VD, VOD) Equipment Application
The LF type ladle refining furnace is used for refining molten steel in primary refining furnaces (electric arc furnaces and converters). It can create a slightly positive pressure reduction atmosphere and adopt submerged arc heating, argon blowing and stirring, white slag refining, alloy composition fine-tuning, and feeding in its atmosphere. Wire and other means are used to degas, desulfurize, remove impurities, and accurately control the composition and temperature of molten steel. It can play a role in buffering and adjusting the continuous casting process.
