Square tubes are shaped like square tubes and are typically rolled from strip steel after being processed. It comes in a range of materials, such as stainless steel, aluminum alloy, steel pipe, etc., and has equal side lengths. Square tubes find extensive application in a variety of constructions, including architectural, decorative, and structural square tubes. ASTM A500 is the most widely used material.
The following steps are typically involved in the production of square tubes:
1. Unpacking the strip: Take the strip out of the reel and pull it together into a single unit.
2. Smoothing: Using chemicals or mechanical means to even out the strip's surface.
3. Curling: A specific shaped round tube is formed by rolling the flattened steel strip.
4. Welding: Create a square tube by welding the round tube.
5. Rolling: Using high pressure and temperature, the square tube is rolled to the desired size.
Cut the square tube to the desired length in step six.
Performance index analysis of square tubes:
The term "plasticity" describes a metal material's capacity to undergo permanent, plastic deformation under load without breaking down.
The hardness of a metal material is its degree of hardness or softness. The most widely used technique for determining hardness in manufacturing is the indentation hardness method, which measures the degree of indentation on the surface of the metal material being tested by pressing an indenter of a specific geometric shape into it while it is subjected to a given load.
Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC), and Vickers hardness (HV) are among the frequently employed techniques.
The mechanical characteristics of metal under static load are indicated by the strength, plasticity, and hardness that were previously discussed. In actuality, a lot of machine parts are subjected to cyclic loading during operation, which causes fatigue in the parts.
4. Effect resilience
Impact toughness is the metal's ability to withstand damage under impact load. Impact load is the load acting on the machine part at a very high speed.
The ability of a metal material to withstand damage—that is, excessive plastic deformation or fracture—under static load is referred to as strength. The strength is further separated into tensile strength, compressive strength, flexural strength, shear strength, etc. because the load acts in the forms of tension, compression, bending, shearing, etc. Different strengths frequently have a certain relationship with one another. Tensile strength is typically employed as the most fundamental strength indicator.
Square tubes' areas of application:
Square tubes are used in many different contexts, including the construction of buildings, bridges, automobiles, machinery, furnishings, etc. It can be altered to meet particular requirements by altering the material, size, surface treatment, etc. To choose the best material and specifications for square tubes, you must carefully analyze the requirements and real application scenarios.
