How to melt a can How to melt a can?

Aluminum and its alloys are important raw materials for economic construction, and are widely used in machinery, construction, automobiles, aircraft, home appliances and packaging materials and other industries. After the 80s, the world's aluminum industry has developed rapidly, and the output has ranked first in non-ferrous metals, and the output of primary aluminum has reached 24.67 million tons in 2001, and the consumption has reached 23.52 million tons.

Although the primary aluminum industry is developing rapidly, it is also constrained by problems such as long construction period, large investment, high energy consumption and serious pollution. In order to make up for the lack of primary aluminum development and meet the growing market demand, all countries attach great importance to the development of recycled aluminum, and recycled aluminum and its products have been widely used in various industrial fields. It is reported that the world's recycled aluminum production has reached more than 8 million tons (excluding China's output), accounting for about 33% of primary aluminum production, and the momentum of rapid development.

China's aluminum industry is developing rapidly, and the current output of primary aluminum has reached 3.57 million tons, ranking first in the world. However, due to the large Chinese population, the current per capita consumption is only, while the per capita consumption of aluminum in the United States is 29kg, and the per capita consumption of aluminum in Japan is much higher than the per capita consumption in China, so China's aluminum and its alloys have broad consumption prospects. In addition, China's recycled aluminum industry has developed rapidly in recent years, is in the stage of take-off, with the development of automobiles, motorcycles, construction and packaging industries, the use and output of recycled aluminum are increasing year by year, and the recycled aluminum industry will be more rapid development.

It is understood that China's current annual output of recycled aluminum is at least more than 1 million tons, of which about 600,000 tons of imported aluminum scrap. Among the scrap aluminum used, the utilization of waste cans is still in its infancy. According to the understanding, China's annual production of cans is 10 billion, and the consumption of 3004 alloy is 180,000 tons.

Cans are a commonly used consumable that can be discarded after use. It is reported that China produces at least 80,000 tons of waste cans every year, and also imports some waste cans, with a total of more than 200,000 tons. The material used in the cans is a high-grade aluminum alloy, but due to backward technology, all the waste cans have been downgraded.

So far, there is no enterprise in China that uses waste cans to produce original aluminum alloys. The development of waste cans to produce 3004 aluminum alloy projects will have high environmental, resource and economic benefits.

In recent years, some foreign businessmen have seen the huge potential and broad market prospects of China's waste cans, and have visited China many times, and intend to develop the 3004 aluminum alloy market in China. In addition, the Beijing-Tianjin area is an area with a large number of waste cans, and most of the waste cans produced are transported to Jiangsu and Zhejiang, where they are downgraded and utilized. Therefore, there are several advantages to building this project in Tianjin.

Cans are mostly made of aluminum.

Aluminum is a crystal with a fixed melting point:

The maximum temperature inside the domestic coal furnace can reach 800 degrees Celsius.

Above, blower equipment is required to melt aluminum smoothly.

Blowtorch can also be used, flame temperature.

Up to 800 1000 , can melt aluminum smoothly.

There are also parts made of iron.

Melting point 1535

Don't expect to melt it at home.

Put waste cans.

Mixed in a melting furnace.

1. Directly smelt into coarse aluminum ingots.

Waste cans are mixed in a melting furnace to produce a metal ingot similar to wrought aluminum, which is sometimes counterfeited as pure aluminium ingots on the market, which has a very bad impact.

2. Used for smelting certain grades of alloys: some more standardized enterprises need to add some pure aluminum ingots to adjust the composition when smelting and casting aluminum alloys, but they often increase the magnesium content of the alloy, which is more practical for the production of alloys with higher magnesium content.

3. Mix with other waste cooked aluminum to produce miscellaneous aluminum ingots.

Cans are made of aluminium alloy, which has a melting point of degrees Celsius and can be melted in the following ways: the maximum temperature in the household coal furnace can reach more than 800 degrees Celsius, and blast equipment is required to melt the aluminium smoothly. Blowtorch can also be used, the flame temperature can reach 800 and the simple cover can be 1000, which can melt aluminum smoothly.

Therefore, the can can be melted.

Cans should not be heated. The main material for making cans on the market is aluminum, after aluminum is heated at high temperature, the oxide film on the surface is decomposed, and aluminum molecules are integrated into the beverage after drinking, which will be bad for health. <

On an ordinary coal stove (with a hair dryer underneath) to make the fire white (up to 1000 degrees), use an iron container (iron will not melt until more than 1500 degrees), and put it in a can.

When it is burned to about 600 degrees, it will melt.

The cans are made of aluminium powder, which burns violently when heated in the air and emits a dazzling white flame. Soluble in dilute sulfuric acid and nitric acid.

Hydrochloric acid, sodium hydroxide.

and potassium hydroxide solution, insoluble in water.

Aluminum is a reactive metal that is aluminium in dry air.

A dense oxide film with a thickness of about 50 angstroms (1 angstroms = nanometers) is immediately formed on the surface, so that the aluminum will not be further oxidized and can resist water; However, the powder of aluminum is extremely flammable when mixed with air; Molten aluminium can correspond violently to water as a metal; Aluminum is amphoteric and highly soluble in strong alkalis and can also be soluble in dilute acids.

1.Direct smelting into coarse aluminum ingots: the waste cans are mixed in the melting furnace to finally obtain a metal ingot similar to wrought aluminum, which is sometimes counterfeit pure aluminum ingots on the market, which has a very bad impact;

2.Used for smelting some grades of alloys: some more standardized enterprises need to add some pure aluminum ingots to adjust the composition when smelting and casting aluminum alloys, but often increase the magnesium content of the alloy, which is more practical for the production of alloys with higher magnesium content;

3.blending with other scrap cooked aluminum to produce miscellaneous aluminum ingots;

4.deoxidizers for steelmaking;

5.Production of aluminium powder: Waste cans are devarted in a rotary kiln and then processed to produce low-grade aluminium powder.

1.Find a used fire extinguisher. 2.

Cut off the bottom half of the used fire extinguisher. 3.Wash the bottom half of the cut with water.

4.Wash the outside too. 5.

Then wipe it all inside and out. 6.Make a few small holes in it.

8.Buy a couple of flamethrowers. 9.

Get the flamethrower's nozzle into that little hole. 10.Use a lighter to start the fire.

11.Put the rest of the can into the cut bottom half. 12.

The flame temperature of the flamethrower should reach 700 1000 . 13.After waiting for a while, the can will melt.

Cans with aluminum and iron are generally smelted separately. Nowadays, there are more furnaces that melt such items with electricity, and the temperature is controllable.
