Description

Technical Field

[0001] This utility model relates to the field of casting and rolling production technology, specifically to an aluminum leakage alarm device for a smelting furnace. Background Technology

[0002] Casting and rolling is a highly efficient production process that combines metal smelting and rolling. It is mainly used for the production of aluminum sheets and strips. Its advantages include a short process flow, directly producing thin strip billets from molten metal through a casting and rolling mill, eliminating the traditional steps of ingot heating and hot rolling, thus significantly reducing investment costs and energy consumption. The casting and rolling process involves rapid cooling and rolling simultaneously, resulting in refined grains, uniform structure, good surface quality, and high dimensional accuracy, which can meet the needs of different users. However, in the process of aluminum alloy casting and rolling, aluminum ingots and scrap aluminum need to be heated to a high temperature of about 760°C in a circular gas-fired smelting furnace. The high-temperature molten aluminum is stirred by electromagnetic stirring in the furnace. Due to the lack of an abnormal outflow alarm device, the high-temperature molten aluminum flows out abnormally from the furnace opening and spreads in all directions, affecting the safety of casting and rolling production and bringing certain adverse effects to actual use. Therefore, improvements are needed. Utility Model Content
