Method for reducing voltage drop of aluminum cell stop

Garment capable of lowering temp

The invention discloses a cooling garment, including a cold matter storage box, a pump, a power supply and a cooling layer, wherein the cooling layer comprises a circulating water channel. A cold-hot circulating system is formed by sequentially connecting the cold matter storage box (9), the pump and the circulating water channel. The cooling garment has the advantages of small volume, light weight, and integration of the refrigeration circulating system and the cooling layer, which is convenient for dressing and walking and is specially suitable for workers performing high-temperature operations; the circulating speed of the refrigeration circulating system can be adjusted, thus, a relatively comfortable temperature can be kept for wearers, and the wearer always feels cool even at a high temperature, thereby improving labor efficiency; meanwhile, temperature can be increased by the cooling garment of the invention when the temperature is low, and the cooling layer becomes a heating-up ...

Method for increasing strength and rigidity of aluminum guide rod and anode large bus bar

The invention provides a method for increasing the strength and the rigidity of an aluminum guide rod and an anode bus, relating to a method for improving the strength and the rigidity of an aluminum guide rod used for aluminum electrolysis and an anode bus. The method is characterized in that the aluminum used to manufacture the anode aluminum guide rod and the anode bus is added with elements of magnesium, silicon and iron, after addition, the weight of magnesium against the weight of aluminum is between 0.4 and 0.6 percent, and the ratio between iron and silicon is more than 1. The method has the obvious advantages of effectively enhancing the mechanical strength and the rigidity of the aluminum guide rod and the anode bus, reducing the surface damage and the deformation of the aluminum guide rod and the anode bus, prolonging the normal service lives of the aluminum guide rod and the anode bus, lowering the voltage drop of fixtures, lowering the labor intensity of workers and improving ...
