Analysis and Countermeasures for Deformation of Flat-Bottom Steel Silo

In the grain storage industry, flat-bottom steel silo are critical infrastructures whose structural stability is directly related to the safe storage and long-term management of grain.

In the grain storage industry, flat-bottom steel silo are critical infrastructures whose structural stability is directly related to the safe storage and long-term management of grain. However, silo body deformation is a common issue that not only affects storage efficiency but also poses potential threats to grain quality. Therefore, it is essential to analyze the causes of silo deformation and implement effective measures for repair and prevention to ensure the safe operation of storage facilities.

Causes of Flat-Bottom Steel Silo Deformation

Uneven Height of Support Channel Steel

During the construction of flat-bottom steel silo, the height consistency of support channel steel, which bears the load of the silo body, is crucial. Uneven height of these supports leads to uneven load distribution, resulting in localized overloading and causing the silo body to deform. This deformation often appears as localized dents or bulges, significantly affecting the overall stability and lifespan of the silo.

Insufficient Precision in Steel Plate Processing

The processing precision of the silo body steel plates directly impacts the quality of the joints between silo sections. If the steel plates are not precisely squared or if there are significant size deviations, the uneven spacing between sections during assembly can introduce internal stress, leading to localized deformation. Additionally, imprecise operations during processing can result in uneven plate edges, increasing the difficulty and risk of deformation during welding.

Improper Welding Techniques

Welding is a critical step in constructing flat-bottom steel silo. The choice and execution of welding techniques directly affect the quality of weld seams and the stability of the silo body. Improper welding practices, such as incorrect welding sequence or parameters, can lead to concentrated welding stress, causing localized deformation. Failure to eliminate residual welding stress promptly during the welding process can exacerbate the deformation.

Ensure Consistent Height of Support Channel Steel

To prevent deformation caused by uneven support channel steel height, precise leveling of the supports is required before installation. Adjust the height of the support channel steel to ensure uniform height across all platforms, ensuring even load distribution on the silo body plates. Additionally, the design of internal lifting lugs should be close to vertical or circumferential stiffeners, or add square plates at the base of the lugs to increase contact area, reducing localized deformation due to uneven stress.

Enhance Precision in Steel Plate Processing

During the processing of silo body steel plates, ensure a flat working surface and even plate layout, and improve the accuracy grade of processing. Key steps like layout cutting should be handled by professionals to ensure precision. Strictly control every step of the processing to ensure uniform spacing between upper and lower silo body sections. This will reduce localized deformation from forced assembly.

Optimize Welding Techniques

Rational welding techniques are crucial for controlling silo body deformation. When determining the welding sequence, consider the distribution and elimination of welding stress. For vertical and circumferential welds, use segmented back welding or skip welding to minimize stress concentration. Additionally, promptly hammer the welds during the process to eliminate residual welding stress. In cases where gaps between plates or variations in welder skill prevent single-pass welding, employ multi-pass welding. Ensure stress elimination after each pass.

Conclusion

Silo body deformation is a significant factor affecting the safe operation of storage facilities, with complex and varied causes. By thoroughly analyzing these causes and implementing effective repair and prevention measures, the risk of deformation can be significantly reduced, enhancing the overall stability of storage facilities. Continuous research and innovation in the construction and maintenance techniques of flat-bottom steel silo are essential. These efforts provide robust support for the healthy development of the grain storage industry.
