In this paper, the principle, advantages and disadvantages of the current modification technology of vegetable oil and the modification technology used in bio-based degradable lubricating oil were analyzed. The performance of bio-based degradable lubricating oil and mineral-based lubricating oil was compared, and bio-based degradable lubricating oil was used instead of mineral-based lubricating oil in aluminum electrolysis multifunctional crane. Bio-based degradable lubricating oil uses green vegetable oil as the main raw material. Compared with mineral-based lubricating oil, bio-based degradable lubricating oil has high viscosity index and flash point, low pour point, high biodegradation rate and long service life. Therefore, it has the characteristics of green environmental protection, degradability and renewability. In the application of multifunctional crane, bio-based degradable lubricating oil can meet the performance requirements of actual scenarios such as crane operation heating and large temperature difference between day and night. The lubrication performance is more significant, the friction coefficient is smaller, and the oil film coverage is higher. It can effectively prolong the service life of the crane and improve the production efficiency of aluminum electrolysis.
