Dalian anisotropic steel fan-shaped section is an important structural component widely used in industrial manufacturing and mechanical design, especially in metallurgy, chemical industry, energy and other fields, playing an irreplaceable role. It is usually made of high-strength steel and has a unique fan-shaped geometry, which can adapt to complex working environments and stress conditions.

1、 Definition and structural characteristics of anisotropic steel sector segments

Heterosexual steel sector refers to a sector shaped structural component made of high-strength steel, whose shape and size are customized according to specific application requirements. Compared with traditional circular or rectangular structures, sector segments have the following significant characteristics:

Unique geometric shape: The shape of the sector segment is fan-shaped, which can better adapt to the spatial layout requirements of specific equipment or devices. For example, in the continuous casting equipment of the metallurgical industry, sector segments are used to support and guide the solidification process of steel billets, and their shape matches the contour of the steel billets, ensuring the stability and efficiency of the production process.

Superior stress performance: Due to the use of high-strength steel, the fan-shaped section has excellent tensile, compressive, and torsional properties, and can maintain structural stability under special conditions such as high temperature, high pressure, and high load.

Light weight and high strength: Through optimized design and material selection, the anisotropic steel sector can reduce weight while ensuring strength, thereby reducing the overall load of the equipment and improving operational efficiency.

Strong customizability: According to different application scenarios, the size, curvature, thickness and other parameters of the sector can be flexibly adjusted to meet specific needs.

2、 Manufacturing process of anisotropic steel sector segments

The manufacturing process of anisotropic steel sector segments is complex and precise, mainly including the following steps:

Material selection: Choose suitable high-strength steel such as alloy steel, stainless steel, etc. based on the usage environment and performance requirements. The chemical composition, mechanical properties, and heat treatment process of the material are crucial for the quality of the fan-shaped segment.

Design and Modeling: Use computer-aided design (CAD) software to perform 3D modeling of sector segments, ensuring their geometric shape and dimensional accuracy. At the same time, finite element analysis (FEA) is used to simulate the stress situation of the sector segment under actual working conditions and optimize the structural design.

Cutting and Forming: Advanced technologies such as laser cutting, plasma cutting, or water cutting are used to cut steel into preliminary shapes of fan-shaped segments. Subsequently, the steel is processed into the desired fan-shaped structure through processes such as cold bending, hot bending, or stamping.

Welding and assembly: Welding the cut and formed components to ensure the integrity and strength of the structure. During the welding process, it is necessary to strictly control the temperature, speed, and solder quality to avoid cracking or deformation.

Heat treatment and surface treatment: Improve the hardness and wear resistance of the fan-shaped section through heat treatment processes such as quenching and tempering. In addition, surface treatments such as sandblasting, galvanizing, or painting can enhance its corrosion resistance.

Quality inspection: Ultrasonic testing, magnetic particle testing and other methods are used to perform non-destructive testing on the fan-shaped section to ensure that there are no defects inside and on the surface. At the same time, conduct tests on dimensional accuracy and mechanical properties to ensure that the product meets the design requirements.

3、 Application fields of anisotropic steel sector segments

Heterogeneous steel segments are widely used in multiple industrial fields, mainly including:

Metallurgical industry: In continuous casting equipment, sector segments are used to support and guide the solidification process of steel billets, ensuring uniform cooling and forming of the billets. Its high strength and high temperature resistance make it the core component of continuous casting equipment.

Chemical industry: In chemical equipment, sector segments are used to manufacture key components such as reactors and heat exchangers. Its corrosion resistance and high strength can adapt to the high temperature, high pressure, and corrosive environment of chemical media.

Energy industry: In energy equipment such as thermal power generation and nuclear power, sector segments are used to manufacture components such as boilers and steam turbines. Its excellent mechanical and heat resistance properties can meet the high load operation requirements of energy equipment.
