In the vast world of railway engineering, anticorrosive sleepers are like silent rail guards, carrying the weight and speed of countless trains. However, the manufacturing process of these seemingly ordinary sleepers contains exquisite science and art. Today, we will explore the subtle relationship between the scoring treatment and the oil immersion depth of the anti-corrosion sleepers, and reveal the wisdom and ingenuity behind this process.

Nick: tattoo of sleeper

Nicks, as the name suggests, are grooves carved on the surface of sleepers. These grooves are not random, but carefully designed and strictly controlled. The depth, length, spacing, and even the continuity of the knife marks directly affect the anti-corrosion performance and service life of sleepers.

In the process of scoring, the selection and adjustment of saw head is very important. The wool head and inclined head of the plain sleeper must be sawed off to ensure the flatness and stability of the sleeper. The depth of the notch is strictly required. The notch depth of ordinary sleepers shall not be less than 13mm, while that of high-quality pine wood shall be more than 10mm. The setting of this depth is not out of thin air, but based on the comprehensive consideration of multiple factors such as the density of wood, the penetration capacity of preservatives and the bearing demand of sleepers.

The quality requirements for notches are also stringent. The length of knife marks shall not be less than 10mm, the rate of missing knife marks in the track laying surface shall not exceed 5%, and the number of continuous missing knife marks shall not exceed 3. These detailed regulations ensure that each sleeper can absorb preservative evenly, so as to achieve the best anti-corrosion effect.

Oil immersion: the "source of life" of sleepers

Oil immersion is a key link in the production process of anti-corrosion sleepers. Anticorrosive oil, like the "source of life" of sleepers, penetrates into every cell of wood through notched grooves, giving sleepers the ability to resist decay and moth attack. The standard of immersion depth is usually set at more than 13mm, which complements the depth of scoring, and together constitutes the dual protection of sleeper anti-corrosion.

Perfect fit between scoring and oil immersion

The two seemingly independent processes of scoring and oil immersion are actually closely connected and complementary. The depth and quality of the notch directly determine the effect of oil immersion and the anti-corrosion performance of the sleeper. The depth and uniformity of oil immersion, in turn, verified the accuracy and reliability of the scoring process.

In actual operation, if the defect of plain pillow is found to exceed the technical specification during the scoring process, it must be selected immediately. This strict quality control ensures that each sleeper can achieve the best anti-corrosion effect. At the same time, the timely adjustment of the tool holder ensures the stability of the scoring depth and lays a solid foundation for the smooth progress of the oil immersion process.

epilogue

The scratch treatment and oil immersion depth of anti-corrosion sleepers are indispensable and important links in railway engineering. The relationship between them is not only reflected in the matching of technical parameters, but also in the deep understanding and accurate grasp of wood properties, preservative properties, and sleeper use environment. It is this understanding and grasp that endows the anti-corrosion sleepers with strong anti-corrosion performance and long service life, and ensures the safety and stability of railway transportation.

In the future railway engineering construction, we expect more innovations and breakthroughs, and we expect the manufacturing process of anti-corrosion sleepers to continue to improve, providing a more solid guarantee for the safety and stability of railway transportation.
