Know more about iron lesions
In simple terms, waste refers to materials that can be recycled. Wastes have many applications and can be used in many cases. It is interesting to know that about 10-15% of the materials used in construction are non-metallic wastes, such as bricks and wood. Some wastes such as scrap iron, cast iron, copper and even aluminum can be recovered, and that is exactly why many people are willing to buy this type of waste.
Types of waste
Heavy load: Heavy load is a type of waste whose weight is equivalent to one ton per cubic meter or more.
Special: Steel products used in construction, including small rebars, beams and profile cans. They are used in construction with dimensions below 50 cm.
Super special: Wastes that have a higher value in terms of quality and price are known as super special waste.
First class. : First grade is a type of waste that has elements of phosphorus, sulfur, copper, chromium, nickel and iron in its chemical composition. Second and third grade: The chemical composition of second and third grade waste is the same as first grade. With the difference that the amount of these chemical compounds is different.
Galvanization: Galvanized scraps are made of iron metal with zinc coating, which are resistant to rust. This type of waste is less valuable compared to other types of waste due to the fact that it contains iron.
Alloy: Alloy waste contains elements of nickel, manganese, chromium, molybdenum, vanadium and tungsten, which are found in repair centers. cars are produced and they have a lower price than first and second grade waste.
Aleppo: This type of waste can be used to store food cans.
Sofareh Ahan: Sofareh waste, scraps They are the result of turning steel and iron sections.
The waste production process
Scraps can be produced by tools used by humans or by industries and factories. Excess pieces and cut parts are collected in factories under the title of scrap.
Iron tools that are used in construction are used as iron scraps after they wear out and pass their useful life. Even the body of an accident car is a kind of waste.
It is interesting to know that in recent years, the volume of scrap waste is high and the sale of this product is based on weight. Although the price of non-ferrous metals is lower than ferrous metals, their recycling volume is much higher.
The waste is collected in an open environment, such as a yard or an open warehouse. In recent years, the price of iron waste and scrap iron plays an important role in world markets and they can be used in various industries.
Applications of iron waste
New metal products that have strength: Metal scraps, through a process using an electric arc, can be turned into metals that have high strength. For example, we can mention stainless steel.
Making household tools: making chairs and tables, benches are among the things that are made using scraps.
Art applications: Sculpture
Industrial applications: such as road construction, bridge construction, car production or even airplane production
