Bulb flat steel specifications

The models and specifications of bulb flat steel mainly include parameters such as length, width, and thickness. For example, the theoretical weights of bulb flat steels with specifications of 10, 3, 4, 5, 6, 7, and 8 are 0.24, 0.31, 0.39, 0.47, 0.55, 0.63, and 0.75 kg per meter, respectively. In addition, the standards of bulb flat steels are mostly European or revised versions of European standards, and their appearance is mostly L-shaped, but the head of L is relatively smooth. 12 The main application areas of bulb flat steels are shipbuilding and bridge building, among which marine bulb flat steels are auxiliary medium-sized materials for shipbuilding. In recent years, with the rapid development of the shipbuilding industry, the demand for marine bulb flat steels has also increased.

Specifications and weight calculation methods of bulb flat steels

Ball flat steels are a widely used steel material, usually used to manufacture high-strength moving parts such as turbine impellers, compressor pistons, shafts, gears, racks, worms, etc. This article organizes the relevant specifications and weight calculation methods of bulb flat steels for readers' reference.

1. Specifications of ball flat steel

The specifications of ball flat steel are as follows:

|Specifications|Overall dimensions (mm)|Ball diameter (mm)|Ball pitch (mm)|

----------------------|----------- |-----------1

|Q235B|2.5x32x15|2.5|32|

|Q345B | 2.5x32x15|2.5| 32|

|SS400 | 2.5x32x15|2.5|32|

|A36|2.5x32x15|2.5|32|

|20# | 2.5x32x15| 2.5 | 32|

Note: The data in the table are for reference only. The actual specifications are subject to the specific products.

2. Calculation method of bulb flat steel weight

The calculation method of bulb flat steel weight is relatively simple. The weight can be calculated according to the specifications and length of the bulb flat steel. The formula is as follows: Weight (kg) = length (m) x cross-sectional area (m) x density (kg/m)

Among them, the density can be queried in relevant information. The density of bulb flat steel is about 7850kg/m.

For example, if the specification of a bulb flat steel is Q235B, the outer dimensions are 2.5x32x15, and the length is 3m, then the weight calculation method of the bulb flat steel is as follows: First, calculate the cross-sectional area:

Cross-sectional area (m) = side thickness of outer dimensions (2.5mm) x side width of outer dimensions (32mm) = 0.8x10^-3㎡ Then, substitute it into the formula for calculation:

Weight (kg) = 3m*0.8x10^-3㎡x7850 kg/m≈18.84 kg

The weight of bulb flat steel can be easily calculated by the above formula for readers' reference. Detailed explanation of ball flat steel specifications, application scope and precautions

1. Ball flat steel specifications

Ball flat steel, also known as spherical flat steel, is a kind of steel that has been hot-rolled, has a spherical head structure and is flat. It is mainly made of carbon steel, alloy steel and other materials. Its specifications are generally the ratio of the ball diameter to the width of the flat part. Common specifications are 12*2, 16*3, 20*4, etc. The diameter of the ball flat steel is generally between 10mm and 100mm, and its length also has different options. The length can be customized according to user needs.

2. Application scope

Because of its spherical head and flat characteristics, the ball flat steel has a stronger structure, so it is widely used in machinery manufacturing, building structure, railway turnout, automobile manufacturing and other fields. Ball flat steel plays an important role in various fields. For example, in the construction field, ball flat steel is often used to make stair guardrails, window guardrails, science and technology park fences, etc.; in the field of machinery manufacturing, ball flat steel is widely used in the manufacture of forging machines, injection molding machines, pressure machines, etc.

3. Precautions

1. When using the bulb flat steel, you need to pay attention to whether its quality is qualified. Unqualified bulb flat steel will cause great risks in later use, so it needs to be carefully checked.

2. When cutting and processing the bulb flat steel, professional tools need to be used. The cut should be smooth and no scratches or cracks should be produced.

3. When storing the bulb flat steel, it should be placed in a dry and ventilated place to avoid long-term exposure to a humid environment, which will affect the service life of the bulb flat steel.
