Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal processing, in particular to a production equipment specially used for aluminum scrap extrusion forming. BACKGROUND

[0002] In the sawing and machining process of aluminum products, a large amount of aluminum scrap will be generated. The generation of aluminum scrap makes the originally high-value aluminum become scrap, and how to efficiently recycle and utilize the aluminum scrap has become the focus of the industry.

[0003] At present, aluminum scrap remelting is a common recycling method, but there are many problems.

[0004] Problem 1: Severe oxidation loss and low recovery rate: Aluminum is a lively metal, and the specific surface area of aluminum scrap is large, which is in full contact with air during remelting, and is prone to oxidation reaction to generate aluminum oxide, resulting in reduced aluminum recovery rate and increased cost. In traditional open smelting, the oxidation loss rate can reach 5%-15% or even higher, especially when the furnace temperature fluctuates greatly, the melt is stirred excessively, or the furnace atmosphere is not well controlled, the oxidation reaction is more intense. The generated aluminum oxide slag is hard and suspended in the aluminum melt to form inclusions, which are difficult to remove, affecting the fluidity and casting performance of the remelted aluminum. If not separated in time, it will cause cracks, pores and other defects in the aluminum material, reduce the product qualification rate, and also change the composition of the aluminum melt, affecting its performance.

[0005] Problem 2: High energy consumption and great environmental pressure: The energy consumption of aluminum scrap remelting is significantly higher than that of primary aluminum smelting. The aluminum scrap has a small bulk density, and more energy is consumed to heat it to the melting temperature. In order to remove impurities and reduce oxidation loss, longer smelting time and higher temperature are often required, further increasing energy consumption. For example, the unit energy consumption for heating aluminum scrap to the melting temperature (about 660℃) is 20%-30% higher than that for melting aluminum ingots. In terms of environmental protection, aluminum scrap remelting produces a large amount of pollutants, oil combustion produces harmful gases such as sulfur dioxide and nitrogen oxides, aluminum scrap cleaning wastewater contains cleaning agents and oil stains, and remelting smoke contains aluminum powder, aluminum oxide particles and other dust, which is harmful to the health of operators and pollutes the surrounding environment. With the tightening of environmental protection regulations, enterprises need to invest a lot of money to build waste gas and wastewater treatment facilities, increasing costs and management difficulty.

[0006] Problem 3: Security risks and economic problems are prominent: there are many security risks in aluminum scrap remelting, such as water vaporization causing melt spatter, aluminum scrap accumulation encountering open fire or high temperature may spontaneously combust, contact with certain chemicals may produce flammable and explosive gases such as hydrogen, there is an explosion risk, and harmful smoke generated by remelting may cause poisoning of operating personnel if ventilation is poor. From the economic point of view, the cost-effectiveness of aluminum scrap remelting is challenged, although the cost of aluminum scrap is lower than that of primary aluminum ingot, but the cost of pretreatment, energy consumption, environmental protection treatment and other links is high, leading to the increase of comprehensive cost of remelted aluminum, and the quality stability of remelted aluminum is poor, the product qualified rate is low, the market recognition of remelted aluminum is low, the price is lower than that of primary aluminum, the profit space of extrusion enterprises is affected, and the enthusiasm of enterprises to carry out aluminum scrap remelting business is affected.

Then it enters the discharge cover 318. In the discharge cover 318, a plurality of resistance heaters 319 are used to preliminarily heat the falling aluminum scrap for preheating operation. Then the aluminum scrap enters the heating conveying mechanism 4 for heating and conveying operation, effectively improving the processing efficiency. By starting the feed motor 41, its output end drives the support pipe 43 to rotate, and the support pipe 43 drives the spiral blade 45 to rotate.

Then the aluminum scrap is discharged through the discharge pipe 49, and the electronic metering valve 410 is intermittently started for quantitative discharge to discharge the aluminum scrap quantitatively and improve the finished product quality effect of extrusion molding.
