The application of cast steel material in bridge support has many advantages and benefits:

High strength and carrying capacity: It can provide enough strength to support the huge weight and traffic load of the bridge, ensuring the stability and safety of the bridge.
Durability: It has good corrosion resistance and wear resistance, and can maintain its performance for a long time under various environmental conditions, reducing maintenance needs.
Good toughness: it can withstand a certain degree of shock and vibration, and adapt to the dynamic load that the bridge may encounter during use.
Strong designability: It is convenient to customize the production according to the specific design requirements and stress characteristics of the bridge to achieve the best support effect.
Reliable connection performance: It is conducive to solid connection with other bridge components to ensure the integrity of the overall structure.
Adapt to complex stress conditions: can better cope with the complex stress distribution and stress state on the bridge.

For example, in some large cable-stayed Bridges or suspension Bridges, cast steel tower support components play a key bearing role; In some Bridges with special structures, such as arch Bridges, cast steel joints can effectively transfer and disperse forces to ensure the stability of the bridge. These properties of cast steel make it a reliable and important choice for bridge support, providing a solid foundation for the safe operation of Bridges.

In the bridge support, the following are some commonly used parts of cast steel materials:

Node position: such as the connection node of the beam and column, the connection node of the diagonal brace and the main beam. The cast steel joint can better adapt to the complex stress situation to ensure the effective transfer of force and the stability of the structure.
Support: Used to support the upper structure of the bridge and transfer the load to the lower structure, cast steel supports have high strength and durability.
Support members at the top of the pier: these parts are subjected to high pressures and shear forces, and cast steel materials ensure reliable support.
csome irregular shape but the key force of the connector, cast steel can be precision casting to meet the requirements.
Cable anchorage area: In Bridges with cable, cast steel can be used to manufacture cable anchorage devices to ensure the effective transmission of cable forces.
Key support structures of large Bridges: important positions such as the connection between the main tower and the main beam.

The processing of cast steel parts for Bridges usually includes the following steps:

1. Mold making:
According to the design requirements of cast steel parts, make accurate sand mold or metal mold.
2. Material preparation:
The appropriate cast steel material is selected, smelted and refined to ensure that the chemical composition and quality meet the standards.
3. Pouring:
Molten steel is injected into the mold and allowed to cool and solidify.
4. Stripping and cleaning:
After the cast steel parts solidified, it was removed from the mold, and the surface of the sand and other impurities were cleaned.
5. Heat treatment:
According to the need for appropriate heat treatment, such as annealing, normalizing, etc., to improve the mechanical properties and structure of cast steel accessories.
6. Mechanical processing:
Using a variety of machine tools and tools, casting steel accessories are turned, milling, drilling, grinding and other processing, so that it can reach the exact size and shape requirements.
7. Surface treatment:
Rust removal, sand blasting, painting and other surface treatment to improve the corrosion resistance and beauty of cast steel accessories.
8. Quality inspection:
Strict quality inspection of the finished cast steel fittings, including dimensional inspection, flaw detection, mechanical property testing, etc., to ensure their quality.
