Technical Field

[0001] This utility model relates to the technical field of molten metal detection, specifically to a slag analyzer. Background Technology

[0002] The slag analyzer is a dual-function device specifically designed for detecting relevant parameters of molten iron slag. It plays a crucial role in quality control and process optimization in the iron and steel smelting and casting industries. Through specific detection technologies, the slag analyzer can quickly and accurately obtain important information such as the content and properties of molten iron slag, providing strong data support for the steel production process.

[0003] Some high-end slag analyzers for molten iron possess online real-time monitoring capabilities. For example, the German LSS-800 slag analyzer can continuously track changes in slag during the smelting process, promptly detecting abnormal fluctuations in slag composition and content, providing operators with a basis for rapid adjustments to the smelting process. However, these online devices are expensive, have high maintenance costs, and require stringent installation environments. Therefore, there is an urgent need to design a slag analyzer that is easy to operate and has low equipment purchase and operating costs. Utility Model Content

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] This utility model proposes a slag measuring instrument, including an instrument body 1, which is a movable trolley with four casters 11 mounted on its bottom. Two sliding grooves are mounted on the instrument body 1, and a detection frame 2 is slidably connected within these grooves, allowing the frame 2 to slide along the grooves. A cylinder 13 is mounted on the instrument body 1, with its output end fixedly connected to the detection frame 2. This means that the cylinder 13 can be used to move the detection frame 2, effectively pushing it out of the instrument body 1 during use.

[0022] A receiving pot 21 is installed on the testing frame 2. A crucible 22 is placed directly above the receiving pot 21. The crucible 22 is fixedly connected to the testing frame 2 by bolts. A leakage hole is opened at the bottom of the crucible 22. The leakage hole is located directly above the receiving pot 21, so that the molten metal in the crucible 22 can flow into the receiving pot 21 through the leakage hole. A filter 3 is installed at the bottom of the leakage hole. The upper surface of the filter 3 abuts against the leakage hole, so that the molten metal that flows through the leakage hole can pass through the filter 3.

[0023] The filter element 3 is connected to the test frame 2 via the mounting part 31. The mounting part 31 is connected to the test frame 2 by bolts. The mounting part 31 has a stepped hole, and the filter element 3 is installed in the stepped hole. The mounting part 31 can securely install the filter element 3 below the leakage hole, and the bolted mounting part 31 can also be more easily disassembled, further achieving the purpose of replacing the filter element 3.

[0024] The testing frame 2 is equipped with cylinder 23. The output direction of cylinder 23 is perpendicular to the output direction of cylinder 13. The output end of cylinder 23 is connected to cover plate 231. Cover plate 231 is adapted to the mouth of crucible 22. That is, after the molten metal is poured into crucible 22, cylinder 23 can drive cover plate 231 to move downward and cover the mouth of crucible 22.

[0025] A weighing device 24 is also installed at the bottom of the testing frame 2. The receiving pot 21 is placed on the weighing device 24, which can weigh the weight of the receiving pot 21 in real time. During the testing process, the weight of the receiving pot 21 weighed by the weighing device 24 is used as a parameter. When the receiving pot 21 reaches a certain weight, the specific gravity of the welding slag rate in the molten metal can be determined by comparing it with the filtration testing time.

[0026] The crucible 22 is also connected to a gas pipe, the other end of which is connected to a pressurizing gas source. This pressurizing gas source is an inert gas source, capable of injecting a certain pressure into the crucible 22, allowing the molten metal to be filtered and tested under constant pressure. An exhaust valve 26 is also installed on the testing rack 2, connected to the crucible 22 for venting. A heating element 221, a spiral heating rod, is also installed inside the crucible 22, heating the molten metal to maintain a constant temperature. A temperature sensor 25 (model M5-HBGT72BGF) is installed on the testing rack 2. The sensor's probe is located inside the crucible and works in conjunction with the heating element 221 to maintain a constant temperature in the molten metal within the crucible 22.

[0027] It should be noted that the instrument is equipped with two gas sources. One is a pressurized gas source, which is filled with inert gas and used to fill the crucible 22. The other is a normal gas source, which is used to maintain the work of cylinder 13 and cylinder 23.

[0028] It also includes a control module 4. The weighing device 24 is electrically connected to the control module 4 to transmit the detected weight information to the control module 4. The output of the control module 4 is electrically connected to a display screen 12, which is mounted on the instrument body 1. The control module 4 outputs a display signal to the display screen 12 based on the weight signal, so that the weight information can be displayed on the display screen 12.

[0029] The control module 4 includes a control unit 41, a storage unit 42, a timing unit 43, a pressure control unit 44, and an electrical control unit 45. The control unit 41 is a PLC programmable controller. The weighing device 24 is electrically connected to the control unit 41. The control unit 41 is communicatively connected to the storage unit 42 and the timing unit 43. The control unit 41 is also electrically connected to the display screen 12. That is, the control unit 41 transmits signals to the storage unit 42 and the display unit based on the weighing signal and the timing signal, so as to realize the function of storing and displaying the detection data.

[0030] The pressure control unit 44 is used to control the pressure of the pressurizing gas source entering the crucible 22 to ensure that the crucible 22 is in a constant pressure state. The constant pressure control is controlled by an 8-bit binary digital valve. The electrical control unit 45 is used to control the various electrical devices in the instrument.

[0031] In summary, the molten metal can drip from the crucible 22 through the filter plate 3 into the container. The slag content can be determined by the filtration time of the molten metal; a longer filtration time indicates a higher slag content and slower filtration, while a shorter filtration time indicates lower slag content and faster filtration. Furthermore, this application features a simple structure, is easy to operate, and has low purchase and transportation costs.
