The technical parameters of the steel casting process are meticulously crafted to suit various steel casting types—be it carbon steel, alloy steel, and more—tailoring to the unique shape, size, and production requirements. Below, discover the essential technical parameters integral to our sophisticated steel casting process:

1. Chemical Composition:
   • Carbon (C): Carbon content in carbon steel castings typically ranges between 0.1% and 0.6%, profoundly influencing the casting's strength, hardness, and toughness. Elevated carbon content enhances strength and hardness, though may slightly reduce toughness.
   • Manganese (Mn): Present usually from 0.5% to 1.5%, manganese boosts the steel's strength and hardenability. It also binds with sulfur, mitigating sulfur's detrimental impacts.
   • Silicon (Si): Typically comprising 0.15% to 0.6%, silicon augments the steel's strength and hardness, while refining its deoxidation capability.
   • Alloying Elements: In alloy steel castings, elements like chromium (Cr), nickel (Ni), molybdenum (Mo), and vanadium (V) are introduced, content depending on the specific steel grade. These elements enhance the casting's properties, fortifying strength, hardness, wear, corrosion, and heat resistance.
2. Melting Temperature:
   • General steel castings melt between 1500°C and 1600°C. This high temperature ensures full dissolution of alloying elements, homogenizing the molten steel's composition. It efficiently expels gases and impurities, elevating the molten steel's quality.
3. Deoxidation Method and Deoxidizer Dosage:
   • Common deoxidizers like ferromanganese, ferrosilicon, and aluminum are employed. The deoxidation approach and deoxidizer quantity are contingent on the steel grade and molten steel quality requirements. Aluminum, with its potent deoxidation capacity, is frequently used for killed steel, typically added in amounts of 0.02% to 0.05%.
4. Pouring Temperature:
   • Pouring temperatures generally range from 1400°C to 1500°C, varying with the casting's size, shape, and complexity. Higher temperatures are essential for thin-walled, intricate castings to ensure efficient mold-filling; conversely, thick-walled castings benefit from lower temperatures to minimize shrinkage cavities and porosity.
5. Performance Parameters of Molding Sand:
   • Permeability: Optimal permeability in molding sand is crucial to allow gases produced during pouring to escape seamlessly, thus averting gas hole defects in castings. Typically, permeability is tailored to the casting's size and type, ranging between 50 and 200.
   • Strength: Molding sand must possess adequate strength to endure the molten steel's pressure and impact, thus avoiding mold damage and sand inclusion defects. Wet strength generally spans 0.1 to 0.3 MPa, with dry strength between 0.8 and 2.0 MPa.
   • Refractoriness: To ensure the integrity and excellence of the casting, the molding sand must exhibit exceptional refractoriness. It should be robust enough to withstand the intense heat and erosive forces of molten steel, with a refractoriness rating of no less than 1500°C. This resilience is crucial for producing superior castings that meet stringent standards.
6. Pouring Speed:
   • The velocity of pouring molten metal significantly influences casting quality. A swift pour may lead to undesirable effects like sand erosion and gas bubbles, while a sluggish pour could result in insufficient filling and cold shuts. For smaller castings, the pouring duration varies from seconds to minutes, whereas larger castings may demand several hours. It's essential to tailor the pouring speed to the unique characteristics of each casting scenario.
7. Heat Treatment Process Parameters:
   • Enhancing the quality and characteristics of steel castings necessitates precise heat treatment processes like normalizing, annealing, quenching, and tempering. Typical normalizing temperatures range from 850°C to 950°C, with holding times adjusted for casting thickness. Quenching is conducted between 800°C and 900°C, while tempering occurs between 500°C and 700°C. These parameters are meticulously selected based on the steel grade and desired casting performance, ensuring optimal results.
