Automatic temperature measuring system for aluminum ingot production and mixing furnace

Abstract

The invention discloses an automatic temperature measuring system for an aluminum ingot production and mixing furnace and belongs to the technical field of casting. The system specifically comprises asupporting mechanism, a transmission mechanism, a temperature measuring mechanism and a control system; limiting blocks are installed at the two ends of the supporting mechanism through bolts, and amotor is installed at the end, away from the temperature measuring mechanism, of the supporting mechanism; the transmission mechanism is connected with the motor through a coupler and is in transmission connection with the temperature measuring mechanism; the temperature measuring mechanism includes a thermocouple and a temperature measuring rod; the control system is a control box disposed outside the temperature measuring mechanism, and the control box includes a control device, an automatic temperature measuring system body, a handheld controller and an alarming apparatus. The system solvesthe technical problems that the workload and the cost are increased since measuring devices are easily damaged in a casting process in the prior art, and measurement data is not precise due to manualoperation.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to an automatic temperature measurement system for a mixing furnace for producing aluminum ingots. Background technique [0002] Electrolytic aluminum plants and aluminum alloy plants measure the timely temperature of metal solution up to 940-970 °C, which is the basic data in terms of production, quality, safety, environment and efficiency. During the casting process of aluminum ingots, the temperature of molten aluminum must be controlled within a certain range in order to ensure the production quality of aluminum ingots. This requires real-time temperature measurement of the molten aluminum temperature, usually by manual operation. The ambient temperature is high and the labor intensity is high, which will cause harm to the human body; in addition, the factory generally uses a temperature measuring device plus a high-chromium alloy protective cover, and the entire measurement se...

Problems solved by technology

During the casting process of aluminum ingots, the temperature of the molten aluminum must be controlled within a certain range in order to ensure the production quality of the aluminum ingots. This requires real-time temperature measurement of the molten aluminum temperature. Usually, the temperature is measured manually. The ambient temperature is high and the labor intensity is high, which will cause harm to the human body; in addition, the factory generally uses a temperature measuring device plus a high-chromium alloy protective cover, and the entire measurement sensor and protective cover are immersed in the high-temperature solution. , fluorine and other corrosive elements, the protective cover of the measuring device is very easy to oxidize, and the thermocouple for temperature measurement will be damaged. Therefore, the thermocouple and the protective cover should be replaced once a week, and the cost is high. The surrounding environment is much higher than the human body can withstand the temperature, it is very inconvenient for workers to operate, and the position of the thermocouple inserted in the temperature measurement is different, which will cause a certain temperature error, and the measurement accuracy cannot meet the requirements of use.
