NOUFERROUS METALLURGICAL EQUIPMENT

The high pressure acid leaching process has been developing fast recently. As its core equipment， the horizontal autoclave is growing ever larger. With such growth in size， load-bearing becomes more complex and danger increases. As a result， finite element analysis （FEA） software has been used to analyze the structural safety of the vessels. To better accommodate the characteristics of the autoclave structure， we made some secondary development based on the existing FEA software using APDL and VB languages， to customize the data input and output modules. The secondary development automates the manual process of model building， grid setting， and complex parameters setting， greatly increasing the efficiency of equipment analysis and design.
