The significant difference between sponge iron and pig iron shows that we can create sponge iron by immediate deduction of iron ore via deduction mechanisms, while the creation of pig iron is by dissolving iron ore with limestone and charcoal at a significantly increased force. Sponge iron and pig iron are various methods of iron that we can create from iron ores that place inherently under the exteriors of the earth. Pig iron and sponge iron possess different usages due to their distinctions in properties. Though there are resemblances, there are also some distinctions between pig iron and sponge iron which we will explain in this article.
What is Sponge Iron?
Sponge iron is a method of iron that we can create immediately from iron ore via a deduction process. This is why we also describe it as “immediately reduced iron”. There, the ore is uncovered to different deduction metabolism, which includes natural gas or a gas that radiates from coal. Also, we can create sponge iron from several furnaces, including oxygen furnaces, blast furnaces, and charcoal ovens. Sponge iron possesses several benefits over several other similarly smelted iron structures. Sponge iron is outstanding to pig iron since it is prosperous in iron content. Due to this property, it possesses several uses in electric furnaces. In its powdered structure, we can combine sponge iron with several other metals to produce a combination of iron-containing derivatives. For example, we can create wrought iron using sponge iron. It is one kind of iron we employ in making cosmetic products, including patio and grill furniture. Wrought iron furniture is in increased demand and stays for years if we care for it properly. Present patterns of producing iron sponges have done away with using deduction gases. Therefore, there is no point in dissolving the ore even.
What is Pig Iron?
Pig iron is a method of iron that we can make by dissolving iron ore with charcoal and limestone under an immensely increased force. When it cools down, the outcome of the product, which we describe as pig iron, is an iron structure with high iron content. Therefore, it turns out to be breakable and dangerous that we can not use it directly in this structure. Although, this iron structure can be refined using further dissolving and blending to make cast iron, wrought iron, and steel, which are used as construction materials. Pig iron is regarded to have been found by the Chinese smiths far back in the 11th-century. The actual structure of pig iron is not beneficial, but outlying processing and refining results in wrought iron and steel, the most popularly used materials on earth.
Difference Between Sponge Iron and Pig Iron
- Sponge iron is described as a structure of iron which we can create directly from iron ore via a deduction process. On the other hand, pig iron is a structure of iron that we can create by dissolving iron ore with limestone and charcoal using an increased force.
- Sponge iron has a high content of iron and reduced content of carbon. Pig iron has a reduced iron content and is very high in carbon.
- Sponge iron is more porous than pig iron, while pig iron is comparatively thick.
- Sponge iron uses a liquid state technique, while pig iron uses a solid state.
