The application of magnesium forgings in construction machinery in environmental protection is of great significance, but it also faces some challenges. The following is an introduction to the applications and challenges in this area:
Applications:
- Lightweight design: Magnesium forgings have the characteristics of low density and high specific strength, which can replace traditional materials, such as steel and aluminum alloy, to achieve lightweight design of construction machinery. Reducing the weight of equipment can reduce fuel consumption and carbon emissions, thus reducing the negative impact on the environment.
- Energy saving and emission reduction: The excellent thermal conductivity of magnesium forgings can improve the heat dissipation effect of the engine and transmission system, reduce energy loss and heat accumulation. In addition, magnesium forgings have good renewability, which can reduce resource waste in the recycling process of waste equipment.
- Corrosion resistance: After reasonable surface treatment and coating technology treatment, magnesium forgings can improve their corrosion resistance and durability. This allows magnesium forgings to be used in harsh working environments, extending the service life of equipment and reducing the emission of waste equipment.
Challenge:
- Corrosion problem: Magnesium has high activity and is easy to react with oxygen, water and other substances in the environment to produce corrosion. This requires the strengthening of corrosion protection measures in the manufacturing and use of magnesium forgings, such as surface treatment, anti-corrosion coating and so on.
- Processing difficulty: the processing performance of magnesium forgings is relatively poor, and problems such as cracks and deformation are easy to occur. Therefore, it is necessary to select appropriate process parameters and strengthen process control in the manufacturing process of magnesium forgings to ensure product quality and processing efficiency.
- Material cost: The high cost of raw materials for magnesium forgings also limits its wide application. Although magnesium is one of the most abundant metal elements on Earth, it is expensive to refine and process. With the improvement of technology and the expansion of scale, the cost of magnesium forgings is expected to gradually decrease.
Environmental protection is crucial to the construction machinery industry. Although magnesium forgings of construction machinery have potential and advantages in environmental protection, it is still necessary to strengthen technology research and development and innovation, overcome challenges, promote its wide use in practical applications, and minimize the negative impact on the environment.
