Problems solved by technology

[0003] At present, electronic belt scales are rarely used to weigh large-sized ores in the metallurgical industry. This is because the distribution of the material layer is uneven when the ore is unloaded, and the ore particle size is difficult to control. For uneven supply of raw materials, the accuracy of weighing must be ensured. , the electronic belt scale is difficult to achieve in parameter control

Abstract

The invention provides a method for calibrating an electronic belt scale. The method comprises the following steps of: making preparation for calibration, namely cleaning and adjusting the electronic belt scale, adjusting a pressure sensor and calibrating a tare value; on the condition that the electronic belt scale operates normally, obtaining the weighed value of a material of which the actual weight is known, and determining a scale error valve according to the actual weight and the weighed valve of the material; repeating the above measuring step so as to obtain multiple scale error values and determining an average scale error value according to the multiple scale error values; and determining a new weighed value correction factor according to the average scale error valve and an original weighed value correction factor and calibrating the electronic belt scale. The method is simple and has an obvious effect; and the calibrated electronic belt scale has high measurement accuracy and can be used for weighing large granular materials.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a calibration method for an electronic belt scale. Background technique [0002] The weighing accuracy of the electronic belt scale directly affects the entire process control of smelting, and indirectly affects the quality and qualification rate of the product. Therefore, the correct calibration method of the electronic belt scale weighing system plays an important role in the entire smelting process. [0003] At present, electronic belt scales are rarely used to weigh large-sized ores in the metallurgical industry. This is because the distribution of the material layer is uneven when the ore is unloaded, and the ore particle size is difficult to control. For uneven supply of raw materials, the accuracy of weighing must be ensured. , Electronic belt scales are more difficult to achieve in parameter control. Therefore, there is an urgent need for a calibration method of the ...
