Embodiment Construction

[0012] The present invention includes a predictive control system that integrates control subsystems, pyrometallurgical models, information from sensors (S1, S2, S3, etc.), operating constraints and process uncertainties, the purpose of which is to determine Control action for the stability of key variables of the process in the melting furnace. Since the system of the invention calculates the control actions, it has a positive impact on the productivity, quality and continuity of the process, which translates into an increase in the movement time of the furnace. As a positive result, furnace damage due to overheating or nozzle or channel leaks is avoided.

[0013] The system consists of four specific subsystems: a subsystem for the detection and quantification of the mineralogy of the dry copper agglomerates by X-ray diffraction (XRD) prior to their injection into the reformer or melting furnace; Subsystems for determining the height of phases or levels of liquid or molten m...

Abstract

The invention provides an integrated intelligent system for controlling variables involved in the process of melting mineral aggregates. The integrated intelligent system comprises four specific subsystems: a subsystem for detecting and quantifying mineralogical types of dry copper aggregates by X-ray diffraction (XRD) before the dry copper aggregates are injected into a reformer or a melting furnace; a subsystem for determining the height of the phase or level of the liquid or molten metal in the melting furnace; a subsystem for measuring the temperature and the thickness of the refractory material of the melting furnace; and a subsystem for on-line and real-time measurement of the percentage of copper in the main product of the melting furnace. Each subsystem has a measurement sensor, in particular for its respective functionality, and integrated into a processor incorporating advanced control software to control the four subsystems, the processor is connected with an interface for data transmitted from the melting furnace.

Description

technical field [0001] This application relates to an integrated intelligent system for controlling the variables involved in the process of melting mineral agglomerates. Specifically, the application relates to an integrated intelligence system that allows the entire melting process operation to be controlled, measuring the mineralogical quality and quantity of the agglomerates injected into the melting furnace as well as variables such as temperature in the furnace, liquid phase levels and percentages of copper. In this way, by reading said variables, the integrated intelligent system autonomously acts on the manipulated variables taking into account the uncertainties, thus allowing to maintain a stable temperature in the reactor, allowing to obtain products of the desired quality and The liquid phase and other controlled variables are controlled to achieve efficient melting. Background technique [0002] Due to the constant search to improve pyrometallurgical melting pr...
