grantor Abstract

Shaft furnace roasting is a common process in the mineral processing industry of hematite in China. The key technology index is the magnetic separation tube recovery rate, reflecting the quality of ore roasting. However, the magnetic separation rate cannot be measured online in real time. In practical production, the control of the recovery rate of the roasting magnetic tube in the shaft furnace is generally achieved through optimization of operation control. The design of operation optimization control strategy requires a large number of industrial field experiments to establish a dynamic response relationship between the magnetic separation tube recovery rate and the main control variables, which is costly and risky. In order to solve this problem, a dynamic model of shaft furnace roasting technology was designed based on the metallurgical simulation software METSIM, and a semi-physical simulation system of the shaft furnace process was established using the same process control software and hardware system as the actual one. The dynamic relationship between the recovery rate of the magnetic separation tube and the set value of temperature during combustion was obtained through simulation experiments and compared with the actual data. This shows that the platform can be used as an experimental and test tool for designing optimization control methods.

Welcome to use KNS55 platform_Save Abstract

Tungsten is a very important strategic mineral resource in China and is widely used in metallurgical, chemical, electronics, aerospace, and military industries. China is a large country of tungsten resources and also a major consumer of tungsten products. With the development of economy and science and technology, the demand for tungsten products has been increasing year by year. At the same time, the quality of tungsten products has also raised higher and higher requirements. On the other hand, with the consumption and reduction of high-grade tungsten resources, the tungsten ore resources processed by tungsten smelting enterprises vary greatly in the grade and composition of impurities, and impurities are numerous. Before each batch of minerals enters smelting production, the ore-phase analysis must be carried out. The process tests and studies determine the best process flow and process parameters. This process is both time-consuming and cost-intensive. Therefore, process theory scholars and tungsten smelting companies have been developing methods and approaches to reduce process test studies at a lower cost and more efficiently. Quickly determine the best smelting process flow and process parameters that are suitable for the changes in the grade and composition of mineral raw materials. Among them, the computer simulation technology of metallurgical process is an effective method. This paper uses tungsten smelting technology as the object and applies computer simulation technology to develop tungsten. The simulation of the smelting process and the optimization of its key process parameters will provide the tungsten smelting company with the best process plan and method to meet the ore source changes at a low cost and high efficiency. The metallurgical simulation system METSIM will be used to simulate the process flow and parameter control of the tungsten smelting process. system. The main research work and conclusions of this paper are as follows. (1) Analyzed the principle and main process parameters of the ball milling-alkali boiling, ion exchange, and APT crystallization processes in the tungsten ion exchange smelting process. Based on this, the METSIM simulation system was used to build the METSIM-based ball milling-alkali cooking and ionization. The process simulation of the exchange and APT crystallization process establishes the tungsten ion exchange smelting process simulation system, and carries out material balance and simulation analysis for each process flow. Comparative analysis shows that the established tungsten ion exchange smelting process simulation system can be better Reflect the actual production process. (2) Applying the established ball-alkali cooking process simulation system, the real-time leaching rate of WO 3 in the process of caustic digestion and the process parameters such as alkali-tungsten ratio can be simulated and compared with the physical process test under the same conditions. The process parameters obtained by the two are similar and the trend of change is consistent. (3) Utilizing the established tungsten ion exchange smelting process simulation system, not only can the simulation test of the tungsten smelting process be carried out to determine the optimal process flow, but also the simulation process flow can be used to carry out the process simulation simulation and control for multiple processes. The process parameters and equipment are analyzed and optimized for control strategies and algorithms. This paper aims at the detection and control of adsorption saturation points in ion exchange processes. The prediction model of ion exchange adsorption saturation point based on BP neural network was established and simulated in the simulation system. It was found that the maximum percentage error between the predicted value and the true value of the arrival time of adsorption saturation point was 0.5%, and the predicted concentration of effluent was true. The maximum percentage error of the value is 0.5%. The above error range is within the allowable range of the project. The simulation and optimization of tungsten ion exchange process studied in this paper provide a feasible means for research and design of tungsten smelting process and analysis of control system.

grantor Abstract

The roasting process of shaft furnace is the key process in magnetite beneficiation process. The roasting quality of shaft furnace directly affects the following process indicators of grinding and magnetic separation process: metal recovery rate and concentrate grade, so it must strictly control its production index: Magnetic tube recovery. However, there are many uncertainties in the process. For example, the coupling between multi-variables is serious and the time lags behind. The key process parameters are difficult to measure on-line or in real-time. As a result, these variables are difficult to control, and the impact on the operating quality of the shaft furnace production process is difficult to determine qualitatively or quantitatively. To conduct an assessment, the control of the recovery rate of magnetic tubes can generally be achieved by running optimized controls. The investment to run optimization control requires a large number of industrial field experiments, which are costly and risky. In order to reduce the risk and cost of on-site commissioning, how to establish an experimental simulation platform for the shaft furnace roasting process has become an important research topic.

grantor Abstract

Vanadium is an important metal element and has a wide range of uses in the metallurgy, aerospace, chemical, and electronics industries. The main method of vanadium extraction in the world is sodium oxide oxidation roasting of vanadium slag. However, this vanadium recovery process has a low recovery rate and causes serious waste of resources; chromium, a companion component of vanadium slag, cannot be recovered synchronously, resulting in the inclusion of six vanadium tailings. Chromium, stacked, creates serious environmental problems. To this end, the Institute of Process Engineering of the Chinese Academy of Sciences has developed an original sublimate method vanadium slag vanadium chromium clean production process, to achieve efficient recovery of vanadium and chromium in vanadium slag under low temperature and atmospheric operating conditions. This technology is currently in the middle stage of scale-up, and it is imperative to scale up and optimize the process. In this paper, the process simulation software METSIM is used to perform material and energy balance calculations on the sub-fused salt vanadium slag vanadium and chromium co-produced cleaner production process, and the pinch analysis technology is used to optimize the heat transfer network of the process.
