Online condition monitoring of Leaf Spring Stack for torpedo Ladle Car

In the steel manufacturing industry, torpedo vehicles transport ladles containing molten metal (temperature of 1400-1500 Deg C) along a rail track. Each Torpedo vehicle is equipped with a pair of leaf spring stacks to support the ladles during transit. 

  INR 500000/-

 
Reward money is paid in exchange of legally acquiring the solution, implementing it to solve the problem and meeting the success criteria. Milestones for paying the reward money would depend upon the complexity of challenge and maturity of the proposed solution, which would be discussed with the solver as soon as the proposed solution is selected by us.

Challenge details:

In the steel manufacturing industry, torpedo vehicles transport ladles containing molten metal (temperature of 1400-1500 Deg C) along a rail track. Each Torpedo vehicle is equipped with a pair of leaf spring stacks to support the ladles during transit. A leaf spring stack comprises 24 leaf springs and bears a load of approximately 200 tons.
The leaf spring stacks are crucial for the safe transportation of molten metal. However, the industry has experienced recurring failures in the leaf spring stacks. These failures pose a significant safety risk as they can lead to the spillage of molten metal and result in unplanned outages, adversely affecting productivity. Detecting leaf spring failures online ( while the car is in service) is challenging, especially during the operational phase of the Torpedo vehicle. Over the past four financial years, there have been many leaf spring failures, causing unplanned outages in the hot metal logistics process. Addressing this issue is imperative to enhance safety, prevent productivity disruptions, and optimize the reliability of the Torpedo vehicle system.

We are seeking solutions that enable real-time monitoring and early indication of the Torpedo"s leaf spring stack failure while in operation, thus indicating the health of spring stack. This approach aims to mitigate safety hazards and minimize unplanned outages in crucial hot metal logistic lines.
Successful submissions should consider the feasibility of implementing the solution within the existing infrastructure. Additionally, providing information on existing, readily available systems or identifying potential startups or companies capable of developing such solutions will enhance your chances.

Slag Pot Crack Detection
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
Slag pots used in blast furnace operations are prone to crack formation due to extreme temperatures, thermal cycling, and mechanical stresses. Current manual inspection methods are subjective and may miss critical defects. The challenge is to develop an automated, non-contact solution to accurately detect, classify, and report cracks on slag pots in a high-temperature steel plant environment, enabling safer and more reliable operations.

Automated Scotching System for Torpedo Ladles
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
Torpedo ladles used for hot metal transportation are currently secured using manually placed wooden scotch blocks, exposing operators to significant safety risks from moving equipment, high temperatures, and pinch points. The plant operates 51 torpedo ladles of varying sizes, with scotching requirements differing based on wheel position and track gradient.The challenge is to develop an automated, remotely operated scotching system integrated onto the torpedo ladle itself, capable of deploying and retracting scotch blocks without manual intervention. The solution must be self-powered, operate reliably in harsh steel plant conditions (up to ~250°C), withstand heat, dust, and sparks, be fail-safe during emergencies, and either use existing wooden scotch blocks or a suitable alternative material with equal or better performance. Modifications to existing equipment or infrastructure may be considered.
