Latest Patents
One of his latest patents is a method and apparatus for removing a nozzle insert from a steelmaking vessel. This invention features a nozzle extraction tool designed to remove a worn nozzle insert efficiently. The tool includes a support frame, a gripper assembly, and a drive piston that applies force to the gripper assembly. The gripper assembly is equipped with pivotal gripper arms and a rod assembly that allows for 360-degree pivoting and rotation around the worn nozzle insert. This design ensures that the gripper arms can securely seat against the uneven surfaces of the worn discharge bore.
Another significant patent by Idstein is a two-piece nozzle insert for use in a steelmaking ladle. This innovative design comprises a nozzle segment and a lock ring segment. The nozzle segment features a prefired refractory block that fits into the discharge bore of a ladle well block. The lock ring segment includes a fastening mechanism for removable attachment within the discharge bore of a ladle mounting plate. The cooperation between the tapered surfaces of the nozzle and lock ring segments creates a slip plane that compresses and extrudes bonding material from the mortar joints of the two-piece nozzle insert.
