Embodiment 1

[0032] A production process of aluminum alloy debris remelting smelting and casting finished products, comprising the following steps:

[0033] Step 1. Degreasing: remove the residue and impurities from the aluminum alloy scraps and put them into an ultrasonic cleaner for at least 30 minutes. 2 times, filter to obtain the aluminum alloy debris after degreasing for use;

[0034] Step 2. Drying: Pour the degreased aluminum alloy scraps into the rotary furnace for baking in Step 1. The aluminum alloy scraps are turned over in the rotary furnace, and the liquid in the aluminum alloy scraps is in the rotary furnace. After being gasified or carbonized, the flue gas is discharged out of the furnace from the flue gas collection and treatment system. At the same time, the dried aluminum alloy chips fall into the bottom of the rotary kiln under the action of gravity. 20ppr / min, until no smoke is discharged from the smoke collection and treatment system, and dry aluminum alloy scraps ar...

Embodiment 2

[0039] A production process of aluminum alloy debris remelting smelting and casting finished products, comprising the following steps:

[0040] Step 1. Degreasing: Put the aluminum alloy shards into an ultrasonic cleaner for at least 30 minutes after removing the residual impurities. 2 times, filter to obtain the aluminum alloy debris after degreasing for use;

[0041] Step 2. Drying: Pour the degreased aluminum alloy scraps into the rotary furnace for baking in Step 1. The aluminum alloy scraps are turned over in the rotary furnace, and the liquid in the aluminum alloy scraps is in the rotary furnace. After being gasified or carbonized, the flue gas is discharged out of the furnace from the flue gas collection and treatment system. At the same time, the dried aluminum alloy chips fall into the bottom of the rotary kiln under the action of gravity. 50ppr / min, until no smoke is discharged from the smoke collection and treatment system, and dry aluminum alloy scraps are obtaine...

Embodiment 3

[0046] A production process of aluminum alloy debris remelting smelting and casting finished products, comprising the following steps:

[0047] Step 1. Degreasing: remove the residue and impurities from the aluminum alloy scraps and put them into an ultrasonic cleaning device for ultrasonic cleaning for at least 30 minutes. 2 times, filter to obtain the aluminum alloy debris after degreasing for use;

[0048] Step 2. Drying: Pour the degreased aluminum alloy scraps into the rotary furnace for baking in Step 1. The aluminum alloy scraps are turned over in the rotary furnace, and the liquid in the aluminum alloy scraps is in the rotary furnace. After being gasified or carbonized, the flue gas is discharged out of the furnace from the flue gas collection and treatment system. At the same time, the dry aluminum alloy chips fall into the bottom of the rotary kiln under the action of gravity. 40ppr / min, until no smoke is discharged from the smoke collection and treatment system, an...

Abstract

The invention relates to the technical field of aluminum alloy castings, in particular to a production process for casting finished products through complex smelting of aluminum alloy chips. The production process comprises the steps of: oil removal; drying; smelting: aluminum alloys are fed in a smelting furnace to be smelted into molten aluminum alloys; preheated aluminum alloy chips with a weight percentage of 45-55% are fed in the smelting furnace; slag is removed after smelting; the preheated aluminum alloy chips with a weight percentage of 20-25% are fed in the smelting furnace; the slagis removed after smelting; the remained preheated aluminum alloy chips are totally fed in the smelting furnace for smelting; the slag is removed after smelting; and the molten aluminum alloys are obtained after smelting for future use; refining; and casting. The production process solves the problems of high machining cost of aluminum alloy chips and high energy consumption in the prior art, andhas the advantages of low energy consumption, low cost, adaption to the industrial production and high quality of prepared aluminum alloy ingots.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting, in particular to a production process of aluminum alloy debris remelting and casting finished products. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . ...
