SCALE-UP METHOD FOR METALLURGICAL PROCESS

摘要

A scale-up method for a metallurgical process, belonging to the field of metallurgy and chemical industry equipment research and scale up. Said method comprises: using a metallurgical macroscopic reaction kinetics research method to determine an overall rate equation and determine the most critical process step having an influence on a reaction rate, so as to obtain reaction characteristics; determining physical field characteristics of a reactor by using a physical simulation and/or numerical simulation method, and optimizing the reactor; determining a single factor of a reaction period according to the reaction characteristics and the physical field characteristics of the reactor; determining a scale-up number of the single factor according to influence relations of the metallurgical reaction process; and solving the pilot-scale test result using a hot test or simulation means, verifying the scale-up number, obtaining a scale-up plan, and industrializing same, so as to complete the scale-up of the metallurgical process.
