Abstract

The invention relates to the technical field of metallurgy, in particular to a calculating method and device for the metallurgical coke burnout rate. The method comprises the steps that dry basis ash subdata Ad in feed coal, dry basis volatilized subdata Vd in the feed coal and dry ash-free basis volatilized subdata Vdafc in the feed coal are obtained from production historical data; actual ash subdata Adj in coke, dry basis volatilized subdata Vdj in the coke and dry ash-free basis volatilized subdata Vdafj are obtained from the production historical data; residual volatilized subdata Vdc obtained after the feed coal theoretical destructive distillation process is calculated; theoretical ash subdata Adl of the coke is calculated; the burnout rate in dry quenching metallurgical coke is calculated. According to the calculating method for the metallurgical coke burnout rate, the step of calculating the finished metallurgical coke burnout rate is simplified, the data reliability can be sufficiently ensured, the data precision and data source standardization in the data calculation process are ensured, and the finished metallurgical coke burnout rate calculation precision is improved.

Description

technical field

[0001] The invention relates to the technical field of metallurgy, in particular to a method and device for measuring and calculating the burning loss rate of metallurgical coke. Background technique

[0002] In the coal coking industry, dry coke quenching is generally used to cool red coke. During the process of dry coke quenching, due to the CO 2 and O 2 The existence of red coke has caused the red coke to be continuously oxidized and burned. In the production process, the burning loss ratio of red coke should be controlled as much as possible to reduce the coke loss in the process of dry coke quenching. Reducing the burning loss rate of CDQ is a difficult point in the CDQ industry at present. There are also many methods for calculating the burning loss rate. How to calculate it accurately is also a topic often discussed in the industry.

[0003] At present, the commonly used methods for calculating the loss rate of red coke are: coal consumption method ...
