Refractories for Converters
(Multi Hole Plug (MHP) and Tap Hole Sleeve (THS))

Our gas blowing nozzles (MHPs and CB nozzles) and tap hole sleeves (THSs) dominate the market both in Japan and overseas.
Gas blowing nozzles are used for mixing molten steel in a converter or an electric furnace.
Tap hole sleeves are refractory of cylindrical form and used for tapping molten steel into a ladle, after the steel was processed.
They are both made of MgO-C material and shaped with a high-pressure rubber- press machine.
