The technical parameters of the steel casting process are tailored to the unique requirements of each casting type, whether it be carbon or alloy steel. These parameters depend on factors such as the casting's shape, size, and production specifications. Here, we present an overview of some prevalent technical parameters inherent in the steel casting process that ensure optimal performance and quality.

1. Chemical Composition:
   • Carbon (C): Carbon content in carbon steel castings typically ranges from 0.1% to 0.6%. This component is pivotal, as it fundamentally influences the steel casting's strength, hardness, and toughness. An increase in carbon content enhances strength and hardness, although it could potentially compromise toughness.
   • Manganese (Mn): Typically, manganese content lies between 0.5% and 1.5%. Manganese is instrumental in bolstering the steel's strength and hardenability. It further plays a critical role in binding with sulfur to mitigate sulfur's adverse effects.
   • Silicon (Si): Silicon is generally found in concentrations of 0.15% to 0.6% and is essential for enhancing the steel's strength and hardness. Moreover, it significantly improves the steel's deoxidation capabilities.
   • Alloying Elements: Alloy steel castings are enriched with elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and vanadium (V), with content tailored to the steel grade. These elements play a transformative role by boosting the steel casting's strength, hardness, wear, corrosion, and heat resistance.
2. Melting Temperature:
   • The melting temperature for typical steel castings spans from 1500°C to 1600°C. This elevated temperature ensures complete dissolution of alloying elements, leading to a uniform molten steel composition. It also facilitates the removal of gases and impurities, thereby enhancing the overall quality of the molten steel.
3. Deoxidation Method and Deoxidizer Dosage:
   • Commonly used deoxidizers include ferromanganese, ferrosilicon, and aluminum. The choice of deoxidation method and the dosage of deoxidizers depend on the steel grade and the desired quality of the molten steel. Aluminum, renowned for its potent deoxidation ability, is frequently used in the deoxidation of killed steel, typically added in the range of 0.02% to 0.05%.
4. Pouring Temperature:
   • Pouring temperatures usually range between 1400°C and 1500°C, determined by the casting's size, shape, and complexity. Higher temperatures are preferred for thin-walled and complex shapes to ensure complete mold filling, whereas thicker castings benefit from slightly lower temperatures to minimize defects like shrinkage cavities and porosity.
5. Performance Parameters of Molding Sand:
   • Permeability: Adequate permeability in molding sand is crucial to allow gases generated during pouring to escape smoothly, preventing gas hole defects in the casting. Permeability values, contingent on the casting size and steel type, generally fall between 50 and 200.
   • Strength: The molding sand must possess sufficient strength to withstand molten steel's pressure and impact, safeguarding the mold from damage and preventing sand inclusion defects. The wet strength typically ranges from 0.1 to 0.3 MPa, while dry strength varies from 0.8 to 2.0 MPa.
   • Refractoriness: The refractoriness of the molding sand must be robust, enduring the onslaught of high-temperature molten steel. This resilience is crucial and should typically exceed 1500°C, safeguarding against erosion and ensuring superior casting quality.
6. Pouring Speed:
   • Pouring speed plays a pivotal role in casting excellence. A swift pouring speed may lead to undesirable defects such as sand erosion and gas capture, while a sluggish pace risks insufficient filling and cold shuts. For smaller castings, pouring might last mere seconds to a few minutes, whereas larger pieces could demand a meticulous process extending over several hours. Thus, adjusting the pouring speed to accommodate specific casting conditions is essential for optimal results.
7. Heat Treatment Process Parameters:
   • Steel castings undergo vital heat treatment processes like normalizing, annealing, quenching, and tempering to enhance their strength and structural integrity. Normalizing typically occurs between 850°C and 950°C, with holding times tailored to the casting's thickness. Quenching, performed between 800°C and 900°C, and tempering, between 500°C and 700°C, are calibrated according to the steel's grade and the specific performance criteria required by each casting.
