Introduction
Yilong’s stopper rods are made from alumina-carbon in isostatic
presses with zirconia inserts and/or magnesia tips as necessary for
optimum performance. Argon channels are likewise available to suit a
particular operation. Stopper rods are all X-rayed before shipment to
eliminate flaws and cracks. Stopper rods can be supplied bare or with
mounting hardware as required.
