In this article, we will explore in detail what robotic refractory demolitions are, their benefits and some of alfran’s outstanding success stories in this field.
What are robotic demolitions?
Robotic demolition is an advanced method of demolition that uses remotely controlled robots to dismantle structures and materials. These robots are equipped with specialised tools, such as hydraulic breakers, which enable them to perform demolition tasks with unmatched precision and efficiency.
Unlike traditional demolition methods, which can be dangerous and less accurate, robotic demolition offers a number of significant advantages. Robots can operate in confined and hard-to-reach spaces in industrial furnaces, where it would be risky for workers. In addition, their ability to handle heavy tools and perform repetitive work without fatigue results in increased productivity and workplace safety when demolishing refractories.
Benefits of robotic demolition in refractories
Efficiency and safety
One of the major benefits of robotic demolition in refractory is efficiency. Robots can work continuously without the need for breaks, which significantly speeds up the demolition process. In addition, their ability to operate with high precision minimises the risk of collateral damage to surrounding structures, which is crucial in densely populated industrial environments.
Safety is another key aspect. Robotic demolitions significantly reduce the risk of injury to workers by eliminating the need for workers to be in hazardous areas, as they do not need to stand next to refractory linings. Robots can be remotely controlled from a safe location, allowing operators to stay out of harm’s way while supervising the work, particularly in hot demolition of refractory linings.
Environmental impact
Robotic demolitions also offer environmental benefits. When refractories are being demolished, these robots generate less of a dusty environment than traditional methods, helping to maintain a cleaner and safer working environment. In addition, the precision demolition allows for better recovery and recycling of refractory materials, contributing to more sustainable practices.
