  • Patent number: 11959147
    Abstract: A top-blowing lance nozzle is configured to freely switch an adequate expansion condition so as to control an oxygen-blowing amount and a jetting velocity independently of each other without requiring a plurality of lance nozzles or a mechanically movable part. A lance nozzle is configured to blow refining oxygen to molten iron charged in a reaction vessel while a gas is blown from a top-blowing lance to the molten iron. One or more blowing holes for blowing a working gas are on an inner wall side surface of the nozzle, at a site where the lance nozzle has a minimum cross-sectional area in a nozzle axis direction or at a neighboring site of the site.

  • Publication number: 20240116125
    Abstract: A bolt feeder is for supplying a bolt to a resistance welding machine that performs resistance-welding of a workpiece and the bolt using a lower electrode. The bolt feeder comprises a holding unit configured to receive the bolt fed by a bolt feeding unit with a head located above a shaft, a moving unit configured to move the holding unit, and a pusher member configured to protrude from and retract into a tip end of the upper electrode. The bolt includes a projection on a top surface of the head which is opposite to a surface provided with the shaft. The lower electrode includes an insertion hole into which the shaft is inserted. The shaft is inserted into the insertion hole by the pusher member protruding from the tip end of the upper electrode and pushes an area of the top surface where the projection is absent.
