Publish Time: 2024-12-16
In the field of key additives for metal smelting, melting type medium manganese, medium silicon and medium fluorine flux play a pivotal role. Their production and preparation processes are complex and precise, and many key control points determine the quality and performance of the products.Raw material selection is the first hurdle. The purity of manganese sources, silicon raw materials and fluorine-containing compounds must be strictly controlled. Even a slight excess of impurities may cause a chain reaction in subsequent smelting and affect the activity and stability of the flux. For example, excessive heavy metal impurities will interfere with the metal refining process, so it is necessary to use advanced spectrometers to test the purity of raw materials batch by batch to ensure that they meet the strict formula standards.There is no room for error in the precise batching process. According to the established chemical composition ratio, the amount of medium manganese, medium silicon, medium fluorine and auxiliary components must be accurate to the milligram level. The automated batching system is combined with manual review, and the flow and weight sensors are calibrated in real time to prevent the flux performance from being unbalanced due to batching deviation, ensuring that each smelting has a stable chemical reaction basis.Control of the melting temperature curve is crucial. Specific heating, constant temperature, and cooling ranges are directly related to the crystal morphology and phase structure of the flux. Advanced intelligent temperature control furnaces monitor the entire process to ensure uniform heating rate and avoid uneven composition or crystal defects caused by sudden heating and cooling; the constant temperature stage is accurately maintained at the ideal temperature to promote the full fusion reaction of various elements to form a uniform melt, laying a solid foundation for the molding of high-quality products.The stirring process is meticulous. High-speed mechanical stirring or electromagnetic stirring is indispensable in flux smelting. The stirring rate, duration, and angle must be adjusted to ensure that the melt has no dead corner convection, so that manganese, silicon, and fluorine atoms are evenly dispersed, agglomeration is avoided, and the flux microstructure is dense and regular, which improves its reactivity and efficiency during metal smelting.melting type medium manganese, medium silicon and medium fluorine flux The molding process is related to the final appearance. Whether it is granulation, briquetting or block molding, mold accuracy, molding pressure and cooling method are the key. Precise molds ensure regular size, constant pressure shapes a compact structure, and reasonable cooling eliminates cracks and deformations, ensuring the strength and storage resistance of the finished flux, escorting subsequent warehousing, transportation and industrial applications, and ensuring that each batch of flux can be accurately exerted on the metal smelting stage.
