Production Technology, Characteristics and Uses of Precision Cast Iron Parts

Production Process Steps of Precision Cast Iron Parts

Iron Melting: High-purity pig iron is used, and the oxidation reaction is accelerated through heating and the addition of lime or coke to separate the slag.

Alloy Addition: Elements such as carbon, silicon, manganese, molybdenum, and nickel are added according to the chemical composition and application requirements of the cast iron product to form the desired alloy.

Mold Preparation and Casting: The mold (typically made of sand or metal) is prepared, and once the mold is ready, the molten iron is poured into it to cool and solidify.

Cooling and Cleaning: After cooling, the cast iron parts are cleaned. The cooling time is influenced by factors such as the carbon content and the shape of the cast iron parts.

Technologically, precision cast iron parts pursue higher precision and more complex shapes. Their characteristics are as follows:

High Precision: The cast parts have high dimensional accuracy, reducing machining allowances and costs.

Complex Shape Casting: They can be cast into complex shapes that are difficult to process.

Diverse Alloy Materials: They are suitable for various alloy materials, such as carbon steel, stainless steel, alloy steel, copper alloys, aluminum alloys, as well as high-temperature alloys, titanium alloys, and precious metals. They are particularly suitable for alloys that are difficult to forge, weld, or cut.

Production Flexibility: They have strong adaptability and are suitable for different batch productions.

Regarding applications, precision cast iron parts are widely used in multiple fields due to their high precision and excellent physical properties:

Mechanical Field: Used in engine water tanks, cylinder blocks, gearboxes, flywheels, chassis, etc. Their good cutting and machining properties also make them suitable for manufacturing various machine tool beds, columns, beams, and other components.

Construction Field: Used for manufacturing street lights, well covers, bridge piers, drainage pipes, and various architectural hardware fittings such as door and window hardware, locks, etc.

Metallurgical Field: Used for rolling mill rolls, continuous casting machine structural parts, blast furnace cylinders, cooling walls, etc. Their good wear resistance and high-temperature resistance make them suitable for environments with high temperatures, high pressures, and impact loads.

In addition, precision cast iron parts may also be applied in fields such as aerospace, automobiles, and medical devices, which have extremely high requirements for casting dimensions, surface finish, and physical properties.

Notes:
The production process, characteristics, and applications may vary depending on the type of cast iron part, the application scenario, and the technical level of the manufacturer.
When selecting and using precision cast iron parts, assessments and selections should be made based on specific needs and scenarios.
