Efficiency and reliability are at the heart of any power plant’s successful operation. One of the critical components of this is an ash handling system. It ensures that the processes stay environment-friendly without wasting materials. However, power plant operations are quite harsh. These extremities often lead to the breakdown of equipment like ash track drive shafts, leading to significant challenges for maintenance personnel.
We understand these challenges and provide innovative and durable solutions to extend the life of crucial components. One such solution is our LoTherme 470M electrode. It is a high-quality welding electrode made especially for the toughest repair jobs.
Challenges Faced by Ash Track Drive Shafts
Ash track drive shafts are typically made of EN 24 steel and are constantly stressed by high temperatures and compressive forces. Over time, this can lead to metal fatigue and cause the component to break, disrupting operations and requiring costly repair or replacement solutions.
Problem Identification
We encountered a complete fracture in the power plant’s ash track shaft. The shaft was exposed to prolonged stress, which caused this damage. The problem was severe enough to halt operations, highlighting the urgent need for a robust and efficient repair.
Our Solution & Implementation
Our team stepped in with a solution to extend the shaft’s life and restore it to full functionality. Here, our LoTherme 470M electrode was used as it can withstand compressive forces efficiently. We employed proper fixtures and precautions to mitigate distortions and bending during the welding process to ensure this repair was durable. We also used HT rods inside and outside the welding area as additional reinforcement. Intermittent welding and stringer beads were applied to ensure the structural integrity of our repairs.
Result
The drive shaft was restored to full capacity, preventing the need for immediate replacement. This saved the power plant significant costs and minimised downtime, allowing it to continue operating without further disruptions. Check out our case study to know more
The Role of LoTherme 470M
LoTherme 470M is a testament to our innovation and quality. This welding consumable offers several advantages:
- High-Temperature Resistance: LoTherme 470M is engineered to withstand high temperatures, making it ideal for projects in environments like mining and power production.
- Structural Integrity: It is a durable electrode which can withstand friction, impact, heat, and corrosion, reducing the risk of fractures.
- Versatility of Use: It can be used with similar and dissimilar materials, such as carbon steels, low-alloy steels, and manganese steels. Its chemistry is also suitable for welding SS 310 grade without cracking.
At D&H Sécheron, we are dedicated to providing proactive solutions that minimise cost, downtime, and replacement needs. This enables you to have optimal resource allocation and sustainably expand your project/operations to their full potential.
With our LoTherme 470M electrode, a power plant was able to address its challenging need swiftly and efficiently. For more detailed insights into the application of welding consumables, explore our case studies and pick the right one for your welding needs.
