Embodiment approach 1

[0106] Embodiment 1: Trying out a first target measurement value, the principle is to adjust only one weight measurement value so that the recovery rate constraint is satisfied to the greatest extent, and the weight measurement value with the smallest constraint residual error is Significant error term.

Embodiment approach 2

[0107] Embodiment 2: try to gather two first target measurement values, the principle is to adjust only the two weight measurement values ​​accordingly, so that the recovery rate constraint is satisfied to the greatest extent, and the two weight measurement values ​​with the smallest constraint residual error are Significant error term.

[0108] For implementation mode one:

[0109] Consider the recovery constraint as:

[0110]

[0111] Then the constrained residual is:

[0112] 10)

[0113] Where p is the number of measured values ​​of the weight to be detected, k (i)(j)It is the coefficient obtained by reducing the recovery rate constraint. When adjusting the measured values ​​of some weights, the constraint residual becomes:

[0114] 11)r new (i) = r (i) +∑k (i)(j) ·Δx (j) ·w m (i)(j) (i=1,2...n);

[0115] where Δx (j) It is the adjustment amount of the jth material weight measurement value.

[0116] When trying to make up a weight measurement, the constr...

Abstract

The invention discloses a metal balance data error processing method and device. The method comprises the steps of obtaining metal balance data in a metal balance table, performing significant error analysis on the metal balance data, removing the metal balance data with significant errors, and performing coordination processing on the metal balance data to enable the metal balance data to conformto a preset constraint condition. Therefore, by removing the data with significant errors in the metal balance data table, the accuracy of the metal balance data is improved, and the work of technicians can be guided.

Description

technical field [0001] The invention relates to the field of smelting, in particular to a data error processing method and device for metal balance. Background technique [0002] Metal balance is a comprehensive technical management work of smelting enterprises. Metal balance reflects the balance relationship between the metal content of incoming raw ore and the metal content of concentrated ore and tailings. Metal balance tables are usually used to reflect the metal balance relationship. The metal balance sheet contains a number of indicators, such as: raw ore processing volume, raw ore grade, outgoing concentrate volume, concentrate grade, metal content, recovery rate, tailings volume and tailings grade. Metal balance sheets are divided into theoretical balance sheets and actual balance sheets. The theoretical balance sheet does not consider the loss in the process, and the actual balance sheet is obtained according to the actual situation. [0003] However, due to the m...
