Plymouth Foundry: Mastering Traditional Principles of Iron Casting Processes

Plymouth Foundry: Mastering Traditional Principles of Iron Casting Processes

Iron castings, the cornerstone of industrial manufacturing, form the essence of expertise. This chapter delves into the fundamentals of iron castings, elucidating their production process and casting techniques.

What are Iron Castings?

Iron castings are robust products born from the fusion of iron and carbon, boasting a higher carbon content than steel. Ranging from 2 to 4.3 percent, this carbon composition lends iron castings their distinctive properties. Additionally, cast iron comprises silicon, manganese, and trace impurities like sulfur and phosphorus. Originating from iron ore reduction in blast furnaces, liquid iron is cast into crude ingots known as pigs. These pigs undergo remelting alongside scrap and alloying elements in cupola furnaces before being recast into molds, yielding a diverse array of products.

Iron Castings Production

Derived from pig iron, cast iron undergoes a transformation from molten state to finished product through meticulous processes. Whether obtained directly from molten pig iron or via remelting, cast iron production involves careful adjustment of carbon and silicon levels to suit specific applications. Additional elements are incorporated into the melt to achieve desired properties. The casting process entails delivering liquid metal into molds, typically via crucibles, and subsequent cooling to form the desired shape. Casting facilitates the creation of intricate shapes otherwise challenging to produce through alternative methods.

Expertise extends to traditional casting techniques such as sand casting and lost wax casting. These methods, including centrifugal casting and vacuum assist direct pour casting, enable the production of high-quality iron castings, meeting diverse industrial demands.
