Abstract

The invention discloses a calcining zone soft measurement judgment method for an aluminium carbon anode calcining kiln. The method comprises the steps of a, data collection, carrying out temperature collection on the kiln coating surface of the calcining kiln and calculating kiln coating average temperature after collection; b, establishing a calcining kiln coating temperature distribution soft measurement function model for a system, carrying out system modeling on the calcining kiln coating temperature by employing the measured kiln coating average temperature and a position corresponding relationship, thereby obtaining a primary calcining kiln coating temperature distribution fitting function model for the system; c, carrying out iteration optimization on the primary calcining kiln coating temperature distribution fitting function model for the system by employing a least square method, thereby obtaining an optimized calcining kiln coating temperature distribution function model for the system; and d, obtaining a calcining zone soft measurement judgment model after optimization. The method is characterized in that the calcining zone position judgment is accurate, the quality of the calcined coke is optimized, the actual yield of the calcined petroleum coke is improved, and a body device is protected.

Description

technical field [0001] The invention relates to a measurement method in the field of nonferrous metal aluminum smelting, in particular to a soft measurement determination method for the calcination zone of a carbon anode calcination kiln for aluminum. Background technique [0002] Carbon anode calcining kiln is the leading process of carbon anode production. Including calcining kiln and calcined coke conveying system, set of waste heat boiler, soft water station and deaerator system, calcining circulating water system, petroleum coke raw material storage transfer station system, etc. system flow comment figure 1 . The main equipment is a rotary kiln, that is, a calcination kiln. In the rotary kiln, the delayed petroleum coke is subjected to high-temperature heating treatment through the calcination process. After the petroleum coke is calcined at a high temperature of 1250-1350 ° C, the moisture and volatiles in the raw materials are removed to improve The true density, o...
