The invention belongs to the field of ferronickel production, and relates to an energy-saving and environment-friendly automatic control system for flux burdening of a vertical laterite-nickel ore smelting furnace. The control system is characterized by consisting of four parts, namely, a detection unit, an industrial personnel computer, a PLC (programmable logic controller) unit and an executing mechanism. The content includes three parts as follows: 1), Laterite-nickel ore components and flux components are detected and analyzed on line in real time before smelting; 2), the flux matching ratio is calculated and automatic burdening is conducted; and 3), flux matching ratio calculation is perfected. The control system detects the components of every batch of raw materials and flux before entering the furnace, finds out corresponding dreg types of smelting through the computer according to characteristics of an Mg-Si-Ca ternary phase diagram, then works out the required amount of the flux, and adopts automatic control charging. Not only is a great deal of manpower saved, but also the preparation accuracy of smelting furnace charges is ensured.
Description
technical field [0001] The invention belongs to the field of ferronickel production, and relates to an energy-saving and environment-friendly laterite nickel ore smelting shaft furnace flux batching automatic control system, which mainly uses detection technology and PLC technology to realize flux demand calculation and automatic addition before smelting. technical background [0002] At present, a large number of ferronickel production enterprises use laterite nickel ore to produce ferronickel, but the raw material flux addition process is basically completed manually in a certain proportion. This not only requires a large amount of labor, but also the production process cannot be stable due to the fluctuation of the composition of each batch of laterite nickel ore. Invention content: [0003] The purpose of the present invention is to solve the problems of time-consuming and labor-consuming addition of the raw material flux for laterite nickel ore smelting and unstable r...
