Iron is one of the chemical elements that exists in the periodic table with the mark Fe and the atomic number 26. Metal iron is located in group 8 and period 4 of periodic table. This valuable metal is used as an alloy for various materials. Also, this metal has different applications.
Iron is called iron soil which is created in the cutting stage of iron or steel. This iron soil is separated from steel parts after operations such as drilling and burning steel parts and then collected. These iron soils are considered as iron and steel wastes.
Although iron soil is considered as iron waste, it can be used over and over again. By doing so, the perigrade of steel waste in the steel industry is minimized.
Iron soil or iron powder is usually used in two forms: unregenated and revitalized in the industry. The unregenated type is charcoal and black and is oxidized and grayed after the resuscitation process.
Iron soil can be used again in the steel production chain and steel industry. This iron soil plus iron oxide shell, producing a variety of briquettes, pellets or agglomerates is widely used. These products are among the middle products of steel in the steelmaking chain and by producing them from iron cutting soil, these products will actually return to the steel production chain.
This recycled iron soil can be used to produce a variety of brake pads. The return of iron soil to the production cycle of iron oxide shell and iron cutting soil is used and one or more processing stages are performed on it.
Recycled sponge iron can also be used to produce these brake pads, but its quality is lower with pads made of iron soil.
Iron soil is used in a variety of agricultural and horticultural applications such as dumping fruit trees as fertilizers, etc. in fertilizer pits, and in this way, the required iron of plants is supplied to a considerable extent. Iron is a part of the essential micronutrients for plants and if the plant is in iron deficiency conditions, the chlorophyll production stages are impaired and the plant suffers from leaf yellow, which is iron deficiency disease.
Consequently, it disrupts the photosynthesis cycle of the plant and in this case, the growth and fruiting of the plant is significantly reduced. On the other hand, with iron deficiency in plants and considering that animals also feed on plants, the amount of iron in the body of animals is reduced and as a result, the nutritional quality of humans is also impaired.
Soft powder of iron soil or iron chips is used in laboratories related to magnetic field. Other applications of iron soil are their use in devices such as slimes.
Iron soil, which is used in powder form, is widely used in the chemical industry to produce magnetic dyes. To produce chemical dyes, we first analyze the iron soil chemically and then, if approved, we produce the dyes from this material.
Also, this powder of iron soil is used to produce ferrous dyes. These colors made of iron soil have this property that can be used on wood and easily penetrate the wood and increase the resistance of wood to harsh weather.
