Chalco Qinghai Branch recently developed a 160kA lithium salt anode for aluminum electrolysis and put it into use. Anode dregs and excessive consumption are among the concerns of the electrolysis industry. Through research, it has been found that the main reason is that the anode undergoes a redox reaction with O2 and CO2 gas in the electrolytic cell, which intensifies the anode consumption, and at the same time causes the carbon particles in the anode to fall off, resulting in a large amount of carbon slag, which jeopardizes the conditions of electrolytic working conditions. Increases the labor intensity of the electrolysis workers during slag removal. The addition of a certain amount of lithium salt additive to the anode is one of the research approaches to reduce the excessive consumption of the anode. This method can suppress the oxidation-reduction reaction of the anode in the electrolysis cell with O2, CO2 gas and reduce the excessive consumption of the carbon anode. This method is in the experiment. Room has been proven. Qinghai Branch introduced the method into actual production in the homogeneous high-quality anode project. In addition to the determination of the amount of material to be added, the location of the addition, and the development of a feeding device, the engineers and technicians have also passed several experiments to break through the technical problems of unstable and discontinuous feeding. On July 29, the company developed and produced a lithium salt anode on the front line and successfully went offline. To date, the company has produced 550 lithium salt anodes with a pass rate of 99.31%. The type code of tapered roller bearings is 30000, and the tapered roller bearings are separable bearings. In general, especially in the size range involved in GB/T307.1-94 "Rolling Bearings - Tolerances for Radial Bearings", the outer ring and the inner assembly of tapered roller bearings are 100% interchangeable.

The angle of the outer ring and the diameter of the outer raceway have been standardized in the same way as the outer dimensions. Changes are not allowed at the time of design manufacturing. As a result, the outer ring and inner assembly of tapered roller bearings are universally interchangeable worldwide.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with Angular Contact Ball Bearings, the load carrying capacity is large and the ultimate speed is low. Tapered roller bearings are capable of bearing axial loads in one direction and are able to limit the axial displacement of the shaft or housing in one direction
