Steelwork site Initiatives

The KONOIKE Group plays a multi-functional role in undertaking a wide variety of operations in manufacturing processes at steelworks.
We have improved the quality of work and reduced operational loads in various processes within steelworks, by applying drones and carrying out work improvements through the development of various types of equipment.

Work improvements made by applying drones

  • 1. A new surveying method for measuring the stock pile of raw materials, which replaces the conventional ground surveying method with drones that use on-board cameras, has been applied to decrease work time, improve accuracy, and reduce workloads.
  • 2. Conventionally, inspection work on conveyor belts for raw material transport requires considerable manpower and time due to the large areas of steelworks sites.
    By changing the inspection method to use drones equipped with infrared cameras, it has become possible to immediately recognize if there are any components generating abnormal heat or if there is any damage to carrier rollers by inspections carried out in short time periods.
    The successful application of methods for early detection before abnormalities become detrimental can prevent incidents such as fires in conveyor equipment.

Work improvements made through development of ore spillage recovery devices (JP6902251 (B1))

Raw materials that fall and accumulate during conveyor belt transport from ships to yards or from yards to plants is known as “spillage”, and work performed by heavy machinery and workers using human power to collect this spillage and make it possible to be reused is “ore spillage recovery.”
Since the space Under the conveyor’s return belts is small, workers previously had to assume uncomfortable positions during recovery work, which was a significant burden for them. There was also a risk of workers becoming caught in machinery.
By changing work performed in tight spaces that cannot be accessed by general heavy machinery and people to instead use equipment developed by our company, we have succeeded in improving safety while reducing workloads.
Since the production of the first unit of this equipment in February 2020, repeated improvements have been made which include enhanced processing capacity achieved by augmenting its power, and functions to allow operation by remote control as well as semi-automatic operation.

Sales of spillage recovery devices have also begun.
