Development of Mechanical Repairing Technology for Refractories (Rotary Shot Method)

Among conventional repairing technology for refractories, such as spraying or shot casting has been developed for labor saving and skill free of operators. However, the durability of repaired body by such methods was not enough because they usually need much amount of water. On the other hand, we developed a new repairing technology that is rotary shot method, which has a very simple mechanical structure and needs much less amount of water than that of conventional repairing technology. Consequently, it has been enable to achieve a much longer life and labor saving for repairing of steel ladle.
