Description

Technical field

[0001] An intelligent control method for an alumina clinker sintering rotary kiln relates to an automatic control of an industrial thermal process, in particular to an intelligent control method for the production process of an alumina clinker sintering rotary kiln. Background technique

[0002] The alumina production process mainly includes Bayer method, sintering method and Bayer and sintering combined method according to the characteristics of ore processing. The sintering production process in the sintering method or combined method is specially designed for processing low-grade bauxite and Bayer process red mud, mainly including clinker firing, clinker dissolution, semen preparation, decomposition and evaporation, etc. Production processes. Among them, clinker sintering is the key process of alumina production by sintering method and mixed method (combined method). Clinker sintering production is organized around the rotary kiln.
