Technical Field
The invention relates to the field of recovery and smelting of regenerated metals, and particularly belongs to a high-efficiency rotary furnace.
Background
With the development of metallurgical industry and the continuous improvement of the quality of life of people's materials in the contemporary, aluminum products are more and more involved in the daily life of people. For example, automobile hubs, aviation aluminum profiles, aluminum ring-pull cans, aluminum cookers and the like have a large amount of waste gas aluminum products recovered and smelted every year.
At present, the domestic smelting equipment in the secondary aluminum industry is mainly a fixed reverberatory furnace. The thermal efficiency of reverberatory furnaces is generally not high, especially those of the flame type, which are used directly for smelting, is about 25-30%. The recycling of the secondary aluminum by the current recycling equipment and recycling method tends to have higher production cost and needs to consume a large amount of energy. And in the course of smelting, a large amount of flux is consumed in order to suppress oxidation burning, which in turn results in the formation of a large amount of by-products in the form of slag. Generally speaking, the aluminum content in the slag is 40-60%, the slag needs to be cleaned after each furnace is produced, and a common enterprise cools the slag, so that the heat of the slag is lost, the aluminum oxidation loss rate of the slag is increased, and cooling equipment is required to cool the high-temperature aluminum slag, so that additional cost is added.
At present, in the renewable aluminum industry, the combined effect of increasing manufacturing cost and environmental protection is that how to improve productivity and economy to the maximum extent is crucial to companies wishing to live in the market.
