Due to the limitations of the production process, the chemical composition of the traditional casting steel stub cannot be accurately controlled, and the problems such as pores and slag cannot be avoided during the casting process, resulting in easy corrosion during use, and the conductivity is affected.

Structural steel stubs are welded using hot rolled steel materials with high electrical conductivity, few impurities, high density, fewer pores, etc., which reduces the resistivity of the workpiece and improves the electrical conductivity of the workpiece; at the same time, the hot rolled steel material has high strength and plasticity, which reduces the damage rate of the workpiece and improves the quality of the repair.

• Lower maintenance rate: When replacing or repairing structural steel stub legs, it is easy to weld and not easy to break legs, which overcomes the relatively poor welding performance of cast steel stubs.
• When the structural steel stub is used in the electrolysis cell, the voltage drop of the stub itself will be reduced by 5-20mv, and the power consumption of tonnes of aluminium will be reduced by about 15-60KW· h.

• All welds adopt full section welding, and the performance indexes of welds are basically consistent with that of base materials.
• The steel stub is directly welded from low-carbon steel profiles, without pores, slag, coarse grains and other casting defects, which effectively solves all kinds of problems existing in cast steel.
• According to customer needs, steel stub materials are available in a variety of options. Through the choice of materials, we can produce high conductivity, high strength, oxidation resistance and other types of steel stub.
