Delve into the intricacies of our steel casting process, where each specification is meticulously tailored to align with the unique requirements of the steel type-be it carbon or alloy, the dimensions, and the specific production demands. Below, we outline the essential technical parameters that define our steel casting excellence:

1. Chemical Composition:
   • Carbon (C): The carbon content in carbon steel castings typically ranges from 0.1% to 0.6%. This element is a key determinant of the casting's strength, hardness, and toughness. Higher carbon levels enhance strength and hardness but may compromise toughness.
   • Manganese (Mn): Present around 0.5% to 1.5%, manganese plays a pivotal role in boosting the steel's strength and hardenability. It synergizes with sulfur to mitigate its adverse effects, enhancing the overall quality.
   • Silicon (Si): Typically between 0.15% to 0.6%, silicon enriches the steel with greater strength and hardness, while also refining its deoxidation capabilities for superior metal quality.
   • Alloying Elements: In alloy steel castings, elements like chromium (Cr), nickel (Ni), molybdenum (Mo), and vanadium (V) are infused, tailored to the steel grade. These elements significantly elevate properties such as strength, hardness, wear, corrosion, and heat resistance.
2. Melting Temperature:
   • With a melting range of 1500°C to 1600°C, our steel castings guarantee that alloy elements are fully dissolved for a homogenous composition. This high temperature is integral to expelling gases and impurities, thus elevating the purity and quality of molten steel.
3. Deoxidation Method and Deoxidizer Dosage:
   • Deoxidizers like ferromanganese, ferrosilicon, and aluminum are pivotal. The method and dosage hinge on the steel grade and desired molten steel quality. Aluminum, known for its potent deoxidation, is frequently employed in killed steel deoxidation, with dosages ranging from 0.02% to 0.05%.
4. Pouring Temperature:
   • Typically, pouring temperatures between 1400°C and 1500°C are selected based on the casting's size, shape, and complexity. Higher temperatures are vital for thin and intricate shapes to ensure mold filling, while lower temperatures can curb issues like shrinkage in thicker castings.
5. Performance Parameters of Molding Sand:
   • Permeability: Molding sand must offer optimal permeability to allow smooth gas escape during pouring, which prevents gas hole defects. The permeability is tailored to the casting's size and steel type, generally falling between 50 and 200.
   • Strength: Molding sand must possess ample strength to resist the molten steel's pressure and impact, thus preventing mold damage and sand inclusion defects. 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 exceptionally high, capable of withstanding the intense erosion of high-temperature molten steel. This is generally required to exceed a temperature of 1500°C, ensuring durability and performance.
6. Pouring Speed:
   • The velocity at which metal is poured plays a pivotal role in the final quality of the casting. Should the pouring speed be overly rapid, it may result in undesirable defects, such as sand washing and gas entrainment. Conversely, a pouring speed that is too languid can lead to issues like insufficient filling and cold shuts. For smaller castings, the pouring duration might extend from mere seconds to a few minutes, while for larger castings, this period could span several hours. Thus, it's imperative that the pouring speed is meticulously calibrated to suit the specific circumstances at hand.
7. Heat Treatment Process Parameters:
   • To enhance the structural integrity and properties of steel castings, heat treatment processes are generally employed, involving techniques such as normalizing, annealing, quenching, and tempering. The normalizing process typically ranges from 850°C to 950°C, with the holding time adjusted based on the casting's thickness. Meanwhile, the quenching temperature is standardly set between 800°C and 900°C, and tempering occurs within the 500°C to 700°C range. These temperatures and hold durations must be precisely determined in alignment with the steel grade and the specific performance criteria of the casting.
