As a crucial basic raw material in the iron and steel industry, information regarding the size and weight of pig iron is of great significance for production, processing, transportation, and application. In China, the size and weight of pig iron vary due to differences in production processes, uses, and industry standards.Tiegu is a pig iron supplier in China. Our main products include cast pig iron, ductile pig iron, high-purity pig iron, blast furnace pig iron, and steelmaking pig iron.
Based on our experience, today we will share knowledge about the size and weight of pig iron together.
I. General Overview of Common Pig Iron Product Types and Sizes
Steelmaking pig iron is mainly used for converter steelmaking. During the casting process, it is usually cast into lumps. The common size of steelmaking pig iron lumps is generally 200 - 300 mm in length, 100 - 150 mm in width, and 50 - 80 mm in thickness. This size specification facilitates the charging operation in the steelmaking process, enabling it to melt relatively quickly in the converter and participate in the steelmaking reaction.
(II) Foundry Pig Iron
Foundry pig iron is mostly used for casting various mechanical parts, automotive components, pipe fittings, etc. Its shape and size are more diverse to meet the requirements of different casting processes. It commonly comes in sheet and lump forms. Sheet - shaped foundry pig iron usually has a thickness of 10 - 30 mm, a width of 100 - 300 mm, and the length can be customized according to actual needs, generally 500 - 1000 mm. The size of lump - shaped foundry pig iron is similar to that of steelmaking pig iron lumps. However, in some special casting scenarios, there are also larger - sized specifications, such as cube - shaped pig iron lumps with side lengths of 300 - 500 mm, to meet the production requirements of large - scale castings.
Pig iron for ductile iron is a key raw material for producing ductile iron. It is generally processed into relatively uniform granular or small - lump forms. The particle size of granular pig iron is mostly between 5 - 20 mm, and the size of small - lump pig iron is similar to that of small - sized steelmaking pig iron lumps, with a length, width, and height generally around 50 - 100 mm. This size design is beneficial for better controlling the chemical composition uniformity and spheroidizing treatment effect during the production process of ductile iron.
II. Influencing Factors of Pig Iron Weight
(I) Size Factor
The weight of pig iron is directly related to its size. Taking common steelmaking pig iron lumps as an example, based on the above - mentioned size range, the weight of a single lump is approximately 10 - 30 kg. Due to the large size differences in foundry pig iron, the weight variation range is wider. For sheet - shaped foundry pig iron, depending on its thickness, width, and length, the weight of a single sheet may range from 5 - 50 kg. For large - scale lump - shaped foundry pig iron, the weight of a single lump can reach 50 - 200 kg. Due to the granular or small - lump characteristics of pig iron for ductile iron, the weight of a single particle (lump) is relatively light, generally 0.1 - 2 kg.
(II) Density Factor
The density of pig iron is approximately 7.0 - 7.4 g/cm³. The density of different types of pig iron varies slightly, which also affects its weight. For pig iron with the same size, the one with a higher density has a relatively greater weight. For example, certain pig iron containing special alloying elements may have a density closer to 7.4 g/cm³, and its weight will be heavier than that of ordinary pig iron under the same volume.
III. Significance of Size and Weight in Practical Applications
In the production process, appropriate size and weight contribute to improving the production efficiency of the iron and steel industry. For example, during steelmaking, moderately sized pig iron lumps can melt quickly, and during casting, well - matched foundry pig iron can reduce machining allowances.
In the transportation process, small - sized and light - weight pig iron, such as pig iron for ductile iron, is easy to handle and suitable for various transportation methods. Large - scale lump - shaped foundry pig iron requires large - scale loading and unloading equipment and is mostly transported by railway or waterway to reduce costs.
In the storage process, reasonably planning the stacking positions according to the size and weight of pig iron can improve the storage efficiency and safety of the warehouse.
Based on the above explanation, you should have a better understanding of the size and weight of pig iron. As a pig iron supplier, we would like to receive your letter or inquiry. If you have any requests, please feel free to leave a message. Let us serve you.
