Product Description
Metal fusion furnace Centrifugal casting sample furnace Preface: X-ray fluorescence spectroscopy and spark scattering spectroscopy have been used for many years in modern metal production and processing, alloy research, casting, metallurgy and new materials research and development. Analysis samples need a certain shape and size, for powder, chip, granular, block and columnar metal, such as: non-ferrous metal, iron alloy, high quality alloy and other metals, need to be remelted through the process of sample. High frequency induction heating remelting technology has the advantages of fast sample preparation, accuracy, almost no material loss, simple operation, good repeatability and low cost. If the use of vacuum plus inert gas positive pressure protection under the condition of melting, there will be no material loss or oxidation, while the sample uniform. PLC controlled remelting and automatic centrifugal casting can eliminate the interference factors of personnel operation. Compared with the conventional sample preparation method, it has many advantages, such as good repeatability, small loss of sample composition, fast preparation speed and so on. Therefore, centrifugal casting of remelted samples is the best method. Other forms lose the necessary conditions for sealing and melting while adding additional operations. All operation functions need safety control, operation parameters can be accurately displayed. Operating functions include vacuum control, gas flow rate and pressure safety, high frequency heating control, holding time, casting time, cooling water flow, overload protection, overload temperature setting, etc. The sample prepared by X-ray fluorescence spectrometer and spark scattering spectrum analysis needs a certain shape and dimension. The application and development of crucible are mainly in four aspects: the reusable and pollution-free melting crucible, the crucible with high temperature and shock resistance and different geometric shapes. At present, the main materials used in crucible are SiO2, Al2O3, ZrO2 or TiO2. These materials can withstand high temperatures of 1800ºC for a short period of time, which is sufficient for high-performance alloys with high melting points. I. Metal melting furnace Centrifugal casting "Remelting Furnace" domestic status 1. Centrifugal casting method is the best way to remelt samples. Before this, the domestic market is full of foreign equipment such as Germany, Japan and Australia. 2, the selection of the appropriate crucible material and the shape of the crucible also need to be imported, because the crucible in use need high temperature resistance, heat resistance and no pollution of samples and other conditions, more than ten years are made of German Liheng thermal manufacturers of ceramic crucible. 3. Due to the expensive imported equipment and consumables, it is difficult for users to communicate with each other in the process of using technology, which seriously affects the use of equipment and technology promotion. 4. The maintenance time of imported equipment is long and the maintenance cost is extremely high. 5. The high frequency heating frequency of German production refurnaces is too high, exceeding the national standard: electromagnetic radiation protection provisions GB8702-1988. Two, "Guiheng" metal sample furnace (Centrifugal casting sample furnace remelting furnace) Introduction I. Metal melting furnace (centrifugal casting remelting furnace) is a special equipment for sample preparation of X-ray fluorescence spectrometers and direct reading spectrometers. Most of the metals can be remelted for sample preparation as long as they are powder, chip, granular and columnar samples and within a certain size range. Second, the method of centrifugal casting is to throw the molten sample in a mold of a certain shape and size and appropriate material by centrifugal rotation. The advantage of centrifugal casting is that the gas in the mold can be excluded so that the sample does not have sand holes or bubbles; And there is no manual casting error (such as temperature error and time error), to ensure good sample reproducibility; It can ensure that the whole sample preparation process is completed in vacuum and protective gas. Iii. The whole sample preparation process is safe and reliable. The operator will place the sample, close the door cover, set the program, and click the start button to open the door cover after the sample preparation is completed automatically. Four, all kinds of crucible and mold material or shape is our company according to the sample melting conditions, and absorb foreign advanced mature experience to choose the design, production and use, we design and production of ceramic crucible and graphite crucible high temperature resistance, heat shock resistance, have a variety of shapes; The inner layer of ceramic crucible is coated with zirconia to prevent the crucible from contaminating the sample. Solve the problem of repeated use, no contamination of samples and reduce the cost of sample preparation. Five, the flux is pure iron, or all samples. Vi. In the process of melting sample, the function of vacuuming and argon gas protection to prevent sample oxidation. Seven, touch screen operation and PLC control system: after the melting procedure is set, the whole melting process is automatically completed: → inductor rise → heating and vacuum → protective gas rapid temperature rise → constant temperature → inductor fall → centrifugal casting. All operation functions can be safely controlled and operation parameters can be accurately displayed. Operation functions include vacuum control, gas flow, heating high frequency control, holding time, casting time, cooling water flow control and display; And has over current, over pressure, super mild water protection setting function Viii. High frequency power supply is produced by our company. The high frequency frequency is lower than that of imported equipment. Note: The use frequency of the equipment advertised by Germany Lihengge is 0.9 -- 2 MHZ! In a word: our company's centrifugal casting melting furnace design and manufacturing, centrifugal rotation shaft integrated structure, sealing structure and inductor lifting structure have our technology, but also the efforts and wisdom of all staff.Iii.
