Abstract
A system and method are provided for determining the trajectory or falling curves of charge material, particularly charge material distributed in a blast furnace. A video is acquired of the charge as it leaves the chute of the charging equipment at various ring positions. The video is converted to still images that are analyzed to obtain calibration and correction factors. These factors can then be used to extract and calibrate a model for the charging program to vary and control the distribution of charge in a vessel.
Claims20
A method for calibrating a model representing the distribution of material into a vessel, said method comprising the steps of acquiring an image of said material at a predetermined distribution position;
- determining a correlation between a pixel in said image and a unit of distance from an object in said image having a known dimension;
- determining from said image, a portion thereof representing said material;
- and using said correlation and said portion to obtain at least one parameter indicative of the nature of said distribution for calibrating said model.
A system for calibrating a model representing the distribution of material into a vessel, said system comprising:
- an imaging system for acquiring an image said charge material at a predetermined distribution position;
- a light source to illuminate said charge material for obtaining said image;
- a processor in communication with said imaging system for determining a correlation between a pixel in said image and a unit of distance from an object in said image having a known dimension and for determining from said image a portion thereof representing said material and using said correlation and said portion to obtain at least one parameter indicative of the nature of said distribution;
- and an output comprising said at least one parameter, wherein said output may be used to calibrate said model.
