Customized cast steel parts: In recent years, complex space pipe truss steel structures have been widely used in large-scale landmark buildings such as super tall buildings, sports centers, airports, and high-speed railway stations due to their unique and beautiful shapes and short construction periods. Cast steel nodes have been widely used as important nodes in complex space pipe truss steel structure engineering in China due to their ability to avoid significant residual stresses during multi bar welding, design flexibility, and aesthetic appearance. The application of cast steel joints in critical areas with high loads and complex hands directly affects the safety of the entire structure and is of great importance
As a professional large-scale steel casting manufacturer, Yingfeng Cast Steel has been focusing on the research and development, design, casting, and processing of large-scale steel castings since its establishment. Currently, it has the comprehensive ability to provide customers with a range of services from rough casting to finished product processing, as well as a complete set of solutions for key component processing. Next, we will analyze how to produce high-quality cast steel nodes:
Condensation timing
The structure, grain size, direction, and morphology of liquid metals are closely related to the solidification structure of castings, and they have a significant impact on the physical and mechanical properties of castings. The purpose of casting is to obtain the desired structure and control the solidification structure. Therefore, effective methods for controlling the organization include deterioration, incubation, dynamics, crystallization, sequential solidification, rapid solidification, etc.
Control accuracy
The dimensional accuracy and surface roughness of castings are difficult to control due to the influence and constraints of many factors. Castings are also too molded, and achieving net shaping has unique advantages. In terms of structure, the inner cavity and outer shape of castings are molded in one go using casting methods, making them close to the final shape of the parts and minimizing processing and assembly processes. In terms of dimensional accuracy and surface quality, the castings should be able to approach the final requirements of the product, achieving a minimum margin or small margin; On the other hand, preserving the original casting surface is beneficial for maintaining superior properties such as corrosion resistance and fatigue resistance of the casting, thereby improving the product's lifespan.
