Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminium alloy melting furnace, especially to an energy-saving aluminium alloy melting furnace. BACKGROUND

[0002] A melting furnace is an industrial device used to heat solid metals or other materials to a molten state. Its structure generally includes a furnace body, a heating device, a temperature control device, and a feeding and discharging device. The furnace body is made of refractory materials and can withstand high temperatures and ensure that heat is not lost in large quantities. The heating device is diverse, with common methods including gas heating, oil heating, and electric heating, which can provide sufficient heat to melt the materials. The temperature control device can accurately control the temperature in the furnace to ensure that the materials melt within the appropriate temperature range, preventing excessive or insufficient temperature from affecting the melting effect and material properties. Melting furnaces are widely used in metallurgy, mechanical manufacturing, glass processing, and many other industries, such as melting metal ores to extract metals in the metallurgical industry and melting glass raw materials in the glass processing industry. They are key equipment for converting materials from solid to liquid and then processing them into a desired shape.

[0003] An aluminium alloy melting furnace is an industrial device specifically designed to heat aluminium alloy materials to a molten state. It is typically composed of a furnace body, a heating system, a temperature control system, a furnace door, and a transmission device. The furnace body is made of high-temperature-resistant materials to ensure structural stability and sealing in high-temperature environments. The heating system can use various heating methods such as gas, oil, or electricity to quickly and evenly heat aluminium alloy raw materials, allowing them to reach the melting point and melt into a liquid state. The temperature control system precisely controls the temperature inside the furnace, ensuring that the aluminium alloy maintains an appropriate temperature range during the melting process, preventing overheating or insufficient temperature from affecting the quality of the aluminium alloy. Aluminium alloy melting furnaces are widely used in aluminium alloy casting and processing industries and are essential for producing various aluminium alloy products. They effectively improve the production efficiency and quality of aluminium alloys and reduce production costs.
