ഉരുകുന്നതിന് മുമ്പ് അലുമിനിയം സ്ക്രാപ്പ് സംസ്കരണ പ്രക്രിയയും സംസ്കരണവും,The raw materials of recycled aluminium (secondary aluminium) production manufacturer are mostly from aluminium and aluminium scrap through circulation recovery.

These scraps come from different sources and have complex shapes, and it is with some other metals and non-metals.

The compositions range varies greatly and its surface is not clean.

If we can not clean the materials before the melting, that will not only cause molten aluminium absorb gas, produce gas hole, loosening and other defects in melting and casting processes, but also make the materials composition and performance unqualified.

മാത്രമല്ല, there will be lots of harmful gases produced in the production, which pollute the environment greatly.

So in order to ensure the recycled aluminium products quality and improve the factories economic benefit, we must make the pretreatment for the scrap aluminum before the melting.

The purpose of aluminum and aluminum alloy scraps pretreatment:

1.To remove other metals and non-metals contained in the scraps;

2.To classify aluminum scraps according to the alloy composition;

3.To remove the oil stains and coatings on the surface of the aluminum scraps;

4.To make aluminum scraps used most economically and reasonably.

Aluminum and aluminum alloy scraps pretreatment situation

Pretreatment process of aluminum scraps in some developing countries

Some developing countries aluminum and aluminum alloy scraps pretreatment process as the following:

1.For the single variety or aluminum and aluminum alloy scraps with no other impurities, generally no complicated pretreatment is needed, but the bulk aluminum scrap need to be broken (sheared or other methods) into blocks with specifications that meet the requirements, baled the loose aluminum scraps into the block, and classified according to the type and composition of the scraps;

2.For high-grade aluminum scraps (including cast aluminum alloys, deformed aluminum alloys, and pure aluminum, തുടങ്ങിയവ.), large-scale secondary aluminum companies generally remove the inclusions such as soil and directly put them into the melting furnace. In small secondary aluminum companies, പൊതുവെ, the cast aluminum alloy, deformed aluminum alloy, and pure aluminum are manually separated and then used separately;

3.For low-grade scraps, because of its complex composition (containing scrap steel, scrap copper, scrap lead and other metals and plastics, rubber, wood chips and other non-metallic inclusions), manual sorting is mainly used. First screen out the dirt and garbage, then pick out the non-metal and metal scraps.The sorted waste aluminum scrap is mixed, and generally no longer sorting.

The scraps material pretreatment technology is outdated, and simple manual sorting is still used.

The sorting tools are magnets, hammer Etc. Based on our experience, the labor intensity is high, the cost is high, and the sorting quality is poor.

Pretreatment process of aluminum scraps in developed countries

The technological research and application of aluminum scraps pretreatment in developed countries started earlier.

It has realized the mechanization and automation of aluminum scraps pretreatment, which can remove metal and non-metal impurities maximumly, improve production efficiency and sorting quality, and reduce production costs.

The pretreatment process used includes sorting, disassembly, baling, drying and oil removing and surface organic coating film removing.
