The technical parameters of the steel casting process are intricately tailored to suit the demands of each type, such as carbon or alloy steel casting. Varying with the casting's shape, size, and specific production needs, these parameters ensure the highest quality. Discover below some of the most prevalent technical parameters in steel casting that help us achieve precision and excellence:

1. Chemical Composition:
   • Carbon (C): In carbon steel castings, the carbon content spans from 0.1% to 0.6%. This crucial element dictates the casting's strength, hardness, and toughness. As carbon content rises, strength and hardness enhance, although it may cause a reduction in toughness.
   • Manganese (Mn): With a typical presence of 0.5% to 1.5%, manganese elevates the strength and hardenability of steel. It also bonds with sulfur to mitigate its adverse effects, contributing to a superior product.
   • Silicon (Si): Present in amounts ranging from 0.15% to 0.6%, silicon plays a pivotal role in boosting the steel's strength and hardness. Moreover, it enhances the steel's deoxidation capability, ensuring a purer final product.
   • Alloying Elements: Alloy steel castings receive additional elements like chromium (Cr), nickel (Ni), molybdenum (Mo), and vanadium (V), tailored to the specific steel grade. These elements significantly enhance properties such as strength, hardness, wear resistance, and corrosion resistance, making them indispensable for high-performance applications.
2. Melting Temperature:
   • General steel castings require a melting temperature between 1500°C and 1600°C. This high-temperature range is crucial for fully dissolving alloying elements and ensuring a uniform composition. It also efficiently purges gases and impurities, culminating in superior molten steel quality.
3. Deoxidation Method and Deoxidizer Dosage:
   • Incorporating common deoxidizers like ferromanganese, ferrosilicon, and aluminum, the deoxidation process is tailored to the steel grade and molten steel quality demands. Aluminum, notable for its potent deoxidation potential, is frequently used in the deoxidation of killed steel. Typically, aluminum is added in amounts ranging from 0.02% to 0.05%.
4. Pouring Temperature:
   • The pouring temperature usually spans 1400°C to 1500°C, adjusted based on casting size, shape, and complexity. Higher temperatures for intricately shaped or thin-walled castings enhance mold filling, while reduced temperatures for thick-walled castings help prevent defects like shrinkage cavities and porosity.
5. Performance Parameters of Molding Sand:
   • Permeability: Key to preventing gas hole defects, molding sand must have adequate permeability to allow gases to escape during pouring. This value, influenced by casting size and type, generally ranges from 50 to 200.
   • Strength: Molding sand must possess substantial strength to withstand molten steel's pressure and impact, preventing mold damage and sand inclusion. Wet strength typically measures between 0.1 and 0.3 MPa, while dry strength ranges from 0.8 to 2.0 MPa.
   • Refractoriness: The refractoriness of the molding sand is crucial, demanding superior resistance to the ravages of high-temperature molten steel. This remarkable capability must exceed a fiery threshold of 1500°C to ensure optimal performance and durability in the casting process.
6. Pouring Speed:
   • The delicate art of pouring speed intricately shapes the destiny of casting quality. A rapid pace can lead to unwelcome blemishes like sand washing and gas retention. Conversely, a languid pace may result in imperfections such as insufficient filling and cold shuts. For petite castings, this crucial time span ranges from mere seconds to several minutes, while grander castings may demand hours of meticulous attention. Tailoring the pouring speed to the specific demands of each unique situation is of paramount importance for achieving perfection.
7. Heat Treatment Process Parameters:
   • An exquisite transformation awaits steel castings through precise heat treatment, refining their structure and fortifying their properties. This alchemy includes processes like normalizing, annealing, quenching, and tempering. Normalizing is conducted between a toasty 850°C and 950°C, with holding times dictated by casting thickness. Quenching occurs in a realm of 800°C to 900°C, while the soothing embrace of tempering unfolds between 500°C and 700°C. Exact temperatures and durations are meticulously aligned with the steel grade and the casting's performance aspirations.
