This commitment to innovation enables our company to tackle complex challenges and deliver optimal results to our clients. In this article, we take a closer look at what robotic demolition of refractories entails, its benefits, and some of Alfran’s notable success stories in this field.
WHAT IS ROBOTIC DEMOLITION?
Robotic demolition is an advanced method that uses remotely controlled robots to dismantle structures and materials. These robots are equipped with specialized tools such as hydraulic hammers, enabling them to carry out demolition tasks with unmatched precision and efficiency.
Unlike traditional demolition methods, which can be dangerous and less accurate, robotic demolition offers a range of significant advantages. Robots can operate in confined and hard-to-reach areas within industrial furnaces, where it would be risky for human workers. Moreover, their ability to handle heavy tools and perform repetitive tasks without fatigue leads to increased productivity and enhanced workplace safety when removing refractory materials.
BENEFITS OF ROBOTIC DEMOLITION
SAFETY AND EFFICIENCY
Safety is a key aspect. Robotic demolition significantly reduces the risk of injury by eliminating the need for workers to be in hazardous zones, particularly close to refractory linings. Robots are operated remotely from a safe location, allowing operators to supervise the process without exposure to danger—especially during hot refractory demolitions.
One of the greatest advantages of robotic demolition is efficiency. Robots can work continuously without breaks, significantly accelerating the demolition process. Their high precision also minimizes the risk of collateral damage to surrounding structures, which is critical in densely packed industrial environments.
ENVIRONMENTAL IMPACT
Robotic demolition also offers environmental benefits. These systems generate far less dust than traditional methods, contributing to a cleaner and safer work environment. Additionally, the precision of robotic demolition facilitates better recovery and recycling of refractory materials, supporting more sustainable practices.
ALFRAN’S SUCCESS STORIES IN ROBOTIC DEMOLITION
At Alfran, we have completed numerous successful projects using robotic demolition. These include work in preheater towers, furnaces, coolers, and other equipment in cement plants, as well as reverberatory furnace demolitions in the aluminum industry—all marked by a significant reduction in safety incidents and accidents.
In the steel sector, rolling mill furnace demolitions are common. Our robots accessed confined spaces and performed demolitions with a level of accuracy impossible to achieve using traditional methods. This not only led to faster completion times but also increased safety and reduced costs for our clients.

The new global crisis originated by the Covid-19 has changed the world as we knew it. Now, the priority is to reduce the number of people involved in the installation process, to have enough distance between them, and to reduce the working time, to avoid risks of spreading the disease.
In this sense, Alfran recommends the best solution to install dense refractory castables: Alfranjet Shotcrete Technology. Alfran is #1 with Shotcrete Technology through its patented Alfranjet®, with more than 25 years of experience and worldwide references in Cement, Steel and Energy industries among others.

To combat the risks of accidents and damage to health, the application of technical and organizational measures is a priority. These measures are designed to eliminate risks at source or to protect workers through collective protection provisions.
When these measures are not enough, the use of personal protective equipment (PPE) is imposed. The PPE act fundamentally reducing the consequences derived from the materialization of the risk. The protective efficacy will depend on the adequacy of the individual protection equipment at the pre-existing levels of risk.
The correct selection and use of the appropriate PPE will minimize the consequences and damages should the risk materialize. Therefore, the mandatory use of them is of vital importance.
Awareness campaigns in Alfran
With the aim of raising awareness among all employees towards active behavior in the prevention of occupational hazards and advancing their integration at all levels, different Awareness Campaigns will be carried out during 2019.
For this, maximum involvement and collaboration is necessary, highlighting the members of the Health and Safety Committee, Delegates and Prevention Technicians, Intermediate Managers and Project Managers.
