Aluminum melting furnace is a new type of high efficiency and energy saving furnace developed according to the aluminum melting process, it can well meet the requirements of aluminum melting process: strict alloy composition, discontinuous production, large single furnace capacity, etc. It achieves the efficacy of reducing consumption, reducing burnout, improving product quality, reducing labor intensity, improving labor conditions and increasing production efficiency, and is suitable for intermittent operation, melting with gold and more retort materials.
Refractory casting material in molten aluminum furnace application advantages
The molten aluminum furnace overall casting metallurgical furnace technology is a metallurgical furnace masonry method with refractory casting material in the field once casting molding furnace refractory material. According to the information, this technology is characterized by good structural integrity, no brick joints, high overall strength, and therefore a long furnace life. In the domestic non-ferrous metallurgical industry, this technology is tried on some furnace bodies. The working temperature of the round furnace is up to 1200℃, and the maximum working temperature of the stationary furnace is up to 1000℃.
Round furnace using the top of the furnace uncovered charging, small furnace for three doors manual slagging, large furnace for two doors mechanical slagging operations. The raw materials are aluminum ingots, scrap cast bars, scrap profiles and cast rolled aluminum coils. Each stationary furnace also has two doors for slag picking and refining operations. Previously, the furnace body is built with refractory bricks, some parts are very easy to damage, thus affecting the life of the furnace and production efficiency. Zhengzhou website construction and through the molten aluminum furnace with refractory pouring material partial pouring furnace body, in order to improve the overall life cycle of the furnace technical transformation.
In addition to the bottom part of the round furnace bricklaying, furnace wall, slag slope, furnace door frame, furnace door, burner brick, etc. all changed to refractory castable overall pouring. All of them have been replaced with castables as a whole. All the furnace cover and including the big furnace cover and small furnace cover have also been changed to castables as a whole. The service life of the whole casted furnace cover is 3-5 years on average.
