First Point: The outlet liquid level control linkage of the holding furnace (also known as the stationary furnace, including the integrated melting and holding furnace, which refers to the furnace group connected to the casting machine, the same hereinafter). During the casting process (usually after the initial 300-500 mm and before the end), when the outlet liquid level of the holding furnace suddenly rises or is extremely high, or suddenly drops or is extremely low, the supply flow trough gate is cut off, the discharge gate is opened, or the lifting device at the entrance of the distribution trough is disconnected to stop the flow, and the tilting furnace automatically tilts back. Second Point: The liquid level control linkage between the main supply trough and the casting plate or the entrance of the distribution trough (core clause).
During the casting process (usually after the initial 300-500 mm and before the end), when the liquid level of the main supply trough and the casting plate (mold plate) or the entrance of the distribution trough suddenly rises or is extremely high, or suddenly drops or is extremely low (the core of the core), the main supply trough gate is cut off, the discharge gate is opened, or the lifting device at the entrance of the distribution trough is disconnected to stop the flow, and the tilting furnace automatically tilts back. Third Point: The cooling water flow, pressure, and temperature control linkage of the casting plate or crystalliser. After the casting starts normally, when the cooling water pressure and flow of the casting plate (mold plate) or crystalliser suddenly drop, the main supply trough gate is cut off, the discharge gate is opened, or the lifting device at the entrance of the distribution trough is disconnected to stop the flow, the tilting furnace automatically tilts back, and the cooling water temperature is monitored.
Fourth Point: The sudden power and water outage linkage of the casting machine. During the casting process, when the casting machine suddenly loses power or water, the main supply trough gate is cut off, the discharge gate is opened, and emergency water is activated; when the power is out, the emergency power supply (seamless) is activated, the main supply trough gate is cut off, the discharge gate is opened, or the lifting device at the entrance of the distribution trough is disconnected to stop the flow, and the tilting furnace automatically tilts back. Fifth Point: The sudden rise in water temperature at the outlet (return water) of the casting well linkage.
During the casting process, when the water temperature at the outlet (return water) of the casting well rises suddenly in a short time, the main supply trough gate is cut off, the discharge gate is opened, or the lifting device at the entrance of the distribution trough is disconnected to stop the flow, and the tilting furnace automatically tilts back. In emergency situations, through the "five-point linkage," the continuous flow of molten aluminum to the casting plate or distribution trough can be blocked or delayed, thereby preventing the molten aluminum from entering the casting well and causing a potential accident of molten aluminum encountering water. Employees who are familiar with and perform the above tasks well will basically avoid potential hazards.
6. Conclusion In summary, by strengthening organization, hazard investigation and management, regulatory enforcement, enhancing process control, improving technical support, intelligent control, and third-party professional service guarantee measures, by building a hazard investigation and management system and a closed-loop management system, timely discovering and eliminating various accident hazards, deepening hazard management, and a series of measures, risk control and hazard management are in place; safety production work is a long-term and arduous task, we will continue to fulfill our safety production responsibilities with a high sense of responsibility and mission, constantly summarize experiences and lessons, improve safety production systems, strengthen safety production management, maintain our original aspiration and take on our mission, strengthen confidence and act bravely, prevent problems before they occur, and ensure the long-term stability of the company's production and business activities; the journey is long and the wind is strong, the heavy responsibility is upon us again. 》Click to view the AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo Special Report.
