Presentation Materials and inquiries for REX-ROBO™
At steelmaking sites, maintenance work such as replacement of refractories is required by human hands in high-temperature environments, such as in front of molten steel. Moreover, steelmaking sites are not only hot but also have a lot of dust floating in the air, making it a harsh environment.
By automating the tasks performed by humans in such environments with robots, workers can be liberated from heavy labor to achieve more safe and secure operations.
REX-ROBO™ achieves stable operations by performing predetermined movements with robots. Utilizing the strength of robots to repeatedly perform the same movements, it can always carry out accurate work and recordkeeping.
With the rapid decline in the working population, securing workers at steelmaking sites is expected to become a major management challenge in the future.
By shifting heavy physical labor in high-temperature environments to robots and reducing manpower needs, the risk of not being able to secure workers is mitigated, enhancing the business sustainability of customers.
