Raw Iron and Iron ore is also known as crude Iron, have many buyers in the world because they are the first point in manufacturing and producing all kinds of steel products. The price of crude iron is very low and it costs less than other primary products like billets and ingots. Pig iron, also known as pig iron, is an intermediate product in the steel industry, obtained by smelting iron ore in blast furnaces. Pig iron contains a large amount of carbon (3.8% to 4.7%) as well as silicon, manganese, phosphorus and some other substances. The presence of high percentages of carbon makes cast iron brittle and non-ductile. This fragile structure prevents its direct use. On the other hand, as the carbon content increases, the melting temperature of pig iron also decreases. High-carbon coke is used to heat iron ore. As a result, the iron produced has a high percentage of carbon. Cold pig iron is known as commercial pig iron and is sold in the form of ingots or blocks. This type of pig iron is sold as feed to steel production sites. Commercial pig iron can be divided into three categories according to its carbon content and impurity content:
- Alkaline pig iron: used in arc furnaces and steelmaking.
- Cast iron: This pig iron, also known as hematite pig iron, is used to cast gray iron in Koper furnaces.
- And high purity pig iron: similar to ductile iron used to make ductile iron.
Uses of pig iron Traditionally pig iron is turned into wrought iron, but more recently it has been used to make steel. During this process, the pig iron is melted and a powerful air current is directed toward it. This action results in the complete oxidation of impurities such as silicon. In this way, the intermediate product is produced in the form of refined pig iron. 
cost of iron
Raw or crude iron is one of the products that may cost less than other products in the market to produce. Iron works in many different industries. Pig iron is the raw material from which all steel products are made. It is achieved by smelting and separating iron ore, scrap iron, and sponge iron. Pig iron is the raw material from which all steel products are made. It is achieved by smelting and separating iron ore, scrap iron, and sponge iron. Methods of making iron and cast iron 1) Blast furnace (indirect regeneration) 2) Electric arc furnace (direct regeneration) Blast furnace (indirect recovery): Most of the world's crude steel is produced this way. First, iron ore is burned from the top of the furnace with lime and coke to obtain pig iron. The iron is then converted into steel and green steel is produced after the separation of impurities. This method is used in iron making. 
Electric Arc Furnace: For steel production, this method is better than indirect regeneration. In this method, scrap iron or sponge iron is used. In this method, the production rate is increased due to the use of scrap compared to blast furnaces and the cost associated with blast furnace construction is also reduced. The electric arc furnace has less pollution to the environment. To burn the blast furnace, it is necessary to generate heat and heat and regenerate it. Blast furnace fuels are divided into two categories: natural fuels and synthetic fuels. Natural fuels such as bituminous, anthracite, and lignite. In synthetic fuels, coke is more important than charcoal. The advantages of coke include hardness, abundance, more combustibility, cheapness, and porosity. To make coke, several coals with different volatile substances must be mixed together and converted into coke in a special oven, which is called "charring". The chemical composition of coke consists of 94-85% carbon, while the rest includes volatiles, ash, sulfur, and moisture. 
cost of iron per ounce The smallest scale to calculate the weight of iron is per ounce. Sometimes to forge products that don’t need much iron, the cost of the product may go lower but based on the alloys changes. cast iron Cast iron is obtained when heated pig iron is poured into a mold of sand or metal and allowed to cool. In the transformation of pig iron into cast iron, there is no precise and special treatment. malleable cast iron Malleable cast iron is obtained when magnesium and iron silicate are added to cast iron, carbon crystallizes, and turns into graphite balls. It is softer than cast iron, has higher tensile strength, and is used more. 
wrought iron When we melt pig iron and make it spongy, if we clean its impurities like silicon, manganese, and carbon, we get wrought iron. white cast iron The carbon in this cast iron is in the form of iron carbide cementite crystals (Fe3C), which are obtained by cooling the melt. By softening this material, its brittleness can be reduced. cast iron It is an alloy of iron (white cast iron) and carbon and other elements, refined from pig iron and scrap iron. blast furnace slag Slag is molten material formed by the interaction of molten material, iron ore, fuel, and oxide impurities in the metal, and due to these interactions, impurities that should not be present in cast iron are separated from pig iron. The main components of the slag are MgO, Al2O3, SiO2, CaO: together they make up 90% of the slag. The remaining 10% is CaS, MnS, MnO, FeO, etc. After iron ore and fuel, the most important ingredient in the blast furnace charge is the flux. Flux does two things: it melts impurities in iron ore whose melting point is higher than the normal temperature of the furnace. 
Iron price chart
The price of iron should not change from one company to another, but this happens. The reason behind this is that they have different charts for the products. The alloys and the raw material are very different from the last product. In general, a metal can be defined as a hard and strong material that can be polished and polished, that conducts electricity and heat, and is malleable. In the metal industry, they are divided into 2 categories: ferrous metals and non-ferrous (non-ferrous) metals. Non-ferrous metals include copper, zinc, aluminum, brass, phosphor bronze, etc. and ferrous metals include iron, cast iron, and steel. 95% of the metals produced in the world are ferrous metals, which are widely used in various industries such as automobile manufacturing, machine manufacturing, construction, various structures, and ship hulls. 
An important factor contributing to the differences and different properties of iron, steel, and cast iron is their carbon content. Pig iron is high in carbon, and its high carbon content makes it brittle, meaning it will not be able to be rolled and hammered. Carbon also lowers the metal's melting temperature. Iron is obtained by carbonizing pig iron with some scrap iron. Common iron has a carbon content of 2% and its melting point is around 113 degrees Celsius. We say that cast iron, steel, and iron are obtained from pig iron. Pig iron is generally available in white, gray, and semi-grey: - White pig iron; is achieved by rapid cooling of pig iron. This rapid cooling prevents the conversion of carbon to graphite, and white pig iron is hard and brittle with the low silicon content. - Gray pig iron; as a result of gradual slow cooling, pig iron is obtained. This slow rate of cooling of the pig iron causes the carbon to turn to graphite and produce a gray color. It is softer than white pig iron, not brittle, and has a higher silicon content. - Semi-gray pig iron is also between gray and white and is used in the production of cast iron and hard steel. 
Iron ore price
The price of iron ore is very different from one company to another because they use many different kinds of alloys in them. Alloys are metals that consist of two or more metals combined. For example, brass is an alloy and metal composed of "copper" and "zinc". The two metals are melted and mixed together in this way, resulting in another metal called brass. Sometimes alloys are obtained by combining metals with non-metals. Like steel, it is a combination of "iron" and "carbon". If you want the literal meaning of the word "alloy", I must tell you that the word is taken from a French word that means to combine. When making alloys, different atoms are always connected to each other. Sometimes this combination of compounds is complete, like brass alloys; sometimes partially, like steel alloys. Alloys are generally harder and more durable than the metals they are made from. For example, when we combine "iron" with "carbon", we get steel, which is harder and stronger than iron. So by adding another metal called "chromium" our steel becomes stainless steel. Now we list some well-known alloys for you: Gold and decorative coins are alloys of gold and copper. 
Because pure gold is too soft to use too much. British silver coins are made of 92.5% silver and 7.5% copper. Alloys are solid mixtures or solutions of metals that consist of a larger metal called a base metal and one or more metallic or non-metallic elements. Alloys often have properties that differ from their constituents. Depending on how uniformly the elements are mixed, the alloy can be single-phase or multi-phase. The purpose of alloying is to change and improve the toughness, strength, hardness, and other properties of materials. The physical properties of the alloys are described by phase diagrams. Alloys are usually reported as percentages by the weight of their elements. Depending on the number of elements, alloys are called binary, ternary, etc. 
cost of iron per gram
Manufacturing iron and iron products have many hidden costs as well as difficult calculations they have that sometimes happen per gram. Similar to any other product, one of the most important factors in raising or lowering the price of a product is supply and demand in the region. In such a way, when the supply is high and the demand is low; commodity prices fall and when supply is low and demand is high, commodity prices go through a process of rising. The prices of steel products are no exception. E.g; when the inventory of a particular product is low, the price of that product will rise in accordance with supply and demand, while if the inventory of a particular product is high, the price of that product will be affected by factors such as exchange rates and the world market. Continued progress in the base metals markets has caused many investors to move capital and liquidity into the metals markets. With versatile support from investors, the export of steel products is also more prosperous, so today's base metals are very popular on commodity exchanges; valuation experts see positive prospects for this market. 
Among other factors that affect the price of iron, we can mention the price of raw materials. Sudden changes in the steel market and other markets mean that the price of raw materials such as iron ore is not a fixed trend, but constantly changing. If the stocks of these materials are low and on the other hand the demand is high, the price of the raw materials will increase and as a result, the final price of steel will also increase. One of the constant factors that change the price of iron is the change of seasons. Weather changes, holidays, and day lengths in different seasons affect the production, supply, and demand of iron products. For example, in winter due to the cold weather, the construction volume falls more seriously, which is due to the stagnant demand in the housing sector, the demand is reduced, and then the price of iron and others. Steel products are also affected by it.
