Numerical Simulation Of Lead Casting Process And Structure Optimization Of Water Cooling System For Anode Vertical Mold

China is the largest country in the lead production, including production andconsumption of refined lead accounts for roughly half of the global market. The refining oflead in our country mostly adopts the electrolytic refining process, in lead electrolytic refiningprocess, lead anode plate casting molding is one of the important steps before the leadelectrolysis. The most domestic smelting production companies still use small plateproduction, technology is relatively backward, the low level of equipment. In order to get ridof the backward situation, in nearly decade, some large domestic enterprises by introducingforeign advanced plate production process, making the gap between domestic overallproduction level and foreign has been narrowed. But the introduction of foreign advancedlarge plate production equipment requires replacement wearing parts on a regular basis toensure the normal operation of production, anode vertical mold is typical key wearing parts,its service life about half a year, only by imported from abroad is not only expensive, but alsothe purchasing cycle is too long, which severely restricted the development of China’s leadsmelting industry. How to digest and enhance imported advanced large plate productionprocess, is an important topic in the lead anode plate high quality and efficient production.Therefore, urgent need to do anode vertical mold lead casting numerical simulation to explorethe influence of different process parameters and mold structure on anode vertical mold leadcasting production. In the paper, comprehensive use of the theories method and technicalmeans such as thermodynamics, the thermal fatigue life theory, numerical simulation andfinite element technology, to obtain the influence law of casting temperature and coolingwater temperature on the production of lead casting, and optimize the structure of watercooling system of anode vertical mold. The main works in this thesis can be concluded as thefollowing：1) Using SolidWorks software to establish3d entity model of anode vertical mold, andestablish a simplified model for finite element numerical simulation accordingly.2) Using ANSYS software, in six kinds of conditions with different process parameters,do numerical simulation of lead anode plate casting forming process respectively, to obtain thesteady-state temperature field of the mold firstly. On the basis, then do the transient thermalanalysis, obtain the transient temperature field of mold and molten lead (plate). Drawinfluence of different process parameters on the mold temperature distribution and the coolingprocess of molten lead. 3) Application of ANSYS software, in six kinds of conditions with different processparameters, do the thermal stress analysis of anode vertical mold on the basis of thetemperature field analysis respectively, to obtain heat stress distribution of mold. On this basis,do the fatigue life analysis for mold, to get parts of the mold which is easy to damage, anddraw the influence of different process parameters on the life of mold.4) Based on ANSYS software, do flow field analysis of anode vertical moldwater-cooling system, and optimize the structure of water cooling system of anode verticalmold according to the distribution of the flow field.In conclusion, the researches result provides a suitable reference of the selection ofprocess parameters of the casting temperature and the cooling water temperature for the actualproduction provide, also supports theoretical basis for the improvement of efficiency of leadcasting production, the improvement of the life of anode vertical mold,and the reduction ofproduction costs. They have a positive promoting effect to enhance the overall productionlevel of the lead electrolytic refining process in China.
