The technical parameters involved in the steel casting process are tailored to the specific type of steel casting, such as carbon or alloy steel, as well as the unique shape, size, and production requirements of the casting. Below we highlight a selection of key technical parameters that define the steel casting process:

1. Chemical Composition:
   • Carbon (C): The carbon content in carbon steel castings typically ranges from 0.1% to 0.6%. This critical component significantly influences the casting's mechanical properties like strength, hardness, and toughness. While higher carbon content enhances strength and hardness, it may inversely affect toughness, making it a balancing act in steel casting applications.
   • Manganese (Mn): Present in quantities ranging from approximately 0.5% to 1.5%, manganese is crucial for enhancing both strength and the ability of the steel to harden. It also mitigates the adverse effects of sulfur by forming manganese sulfides, thus playing a vital role in the overall casting quality.
   • Silicon (Si): Found in concentrations between 0.15% and 0.6%, silicon contributes to the overall strength and hardness of the steel. Moreover, it boosts the deoxidation capability, ensuring cleaner, higher-quality steel castings.
   • Alloying Elements: Alloy steel castings benefit from the addition of elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and vanadium (V), tailored to the specific steel grade. These elements enhance desirable properties like strength, hardness, wear resistance, corrosion resistance, and heat resistance, setting alloy steel castings apart in demanding applications.
2. Melting Temperature:
   • The melting temperature for standard steel castings falls within the range of 1500°C to 1600°C. This high temperature ensures thorough dissolution of alloying elements, uniform composition of the molten steel, and efficient removal of impurities and gases, thereby enhancing the overall quality of the final product.
3. Deoxidation Method and Deoxidizer Dosage:
   • Common deoxidizers include ferromanganese, ferrosilicon, and aluminum, selected based on the steel grade and desired molten steel quality. Aluminum, known for its potent deoxidation properties, is predominantly used in deoxidizing killed steel, typically added in amounts ranging from 0.02% to 0.05%.
4. Pouring Temperature:
   • The pouring temperature generally ranges from 1400°C to 1500°C, contingent on the casting's size, shape, and complexity. For thin-walled or intricately shaped castings, higher temperatures are necessary to ensure complete mold filling, while thicker castings may allow for slightly lower temperatures to minimize defects like shrinkage and porosity.
5. Performance Parameters of Molding Sand:
   • Permeability: Molding sand must maintain a specific permeability to allow gases generated during pouring to escape efficiently, thus avoiding gas-related defects in the casting. This permeability is usually calibrated between values of 50 and 200, dependent on the casting size and steel type.
   • Strength: The molding sand requires robust strength to endure the molten steel's pressure and impact forces, preventing mold damage and sand inclusion defects. Typically, wet strength ranges from 0.1 to 0.3 MPa, while dry strength spans from 0.8 to 2.0 MPa, ensuring structural integrity throughout the casting process.
   • Refractoriness: The refractoriness of the molding sand is crucial as it must withstand the intense heat of molten steel without faltering, typically needing to exceed an impressive 1500°C.
6. Pouring Speed:
   • The pouring speed plays a pivotal role in determining casting quality. A rapid pouring speed may lead to undesirable outcomes like sand erosion and air entrapment, while an overly slow speed may result in incomplete filling or cold shut defects. In the realm of small castings, pouring duration spans from mere seconds to a few minutes. Conversely, for larger castings, this process can extend over several hours. Fine-tuning the pouring speed is essential and should be meticulously adjusted to suit the specific conditions at hand.
7. Heat Treatment Process Parameters:
   • Steel castings typically undergo heat treatment to enhance their structural integrity and performance. This includes processes such as normalizing, annealing, quenching, and tempering. Normalizing occurs between 850°C and 950°C, with the holding time varying based on the casting's thickness. Quenching temperatures range from 800°C to 900°C, followed by tempering at 500°C to 700°C. These parameters are tailored to the grade of steel and specific performance criteria required for the casting.

Packaging & Shipping

Packaging

Rust Prevention Treatment:
To protect cast steel parts from rust during transit and storage, robust rust prevention treatments are essential. Options like spraying anti-rust paint or applying anti-rust oil are commonly adopted. In environments where corrosion is a significant risk, such as in the chemical or petroleum industries, specialized anti-corrosion coatings may be necessary to ensure long-lasting protection.

Cushioning Packaging:
To safeguard cast steel parts from damage during transport, cushioning materials are indispensable. Utilizing materials like foam plastics, sponges, and air cushion films can effectively prevent collisions and external impacts. For precision cast steel parts, particularly those with stringent precision requirements, multi-layer cushioning packaging is often employed to ensure absolute stability and protection throughout their journey.
