摘要： Relatively uniform spherical shaped solid pellets (prills) may be created by passing molten sulfur through a nested strainer to remove particles that would otherwise become trapped in the system, a drip tray with a heating channel attached on its underside, an injection conduit for delivery of a cooled zone of water to create solid prills, and thereafter moving the prills through a stationary curved screen to remove most of the excess water and a vibrating screen.

摘要： A one-piece refractory stopper rod has an axial bore formed therein for the introduction of inert gas into molten steel within a tundish. A metal bushing insert is compressed into the refractory stopper rod and has a threaded bore which is positioned coaxially with the bore of the stopper rod body. A metal attachment rod having an axial bore therethrough and a threaded lower shank portion is secured within the threaded bore of the metal bushing insert. The metal attachment rod has an upper threaded shank which is adapted to be secured to a stopper rod lifting mechanism associated with the tundish. The metal rod further includes a flanged portion intermediate the upper and lower shank portions which carries an annular chamfered surface. The annular chamfered surface faces a like annular chamfered surface formed in the bore of the stopper rod to define a gas-tight seal at a sealing interface therebetween. The upper shank includes an internally threaded portion adapted to receive a threaded fitting for the introduction of a pressurized inert gas to the stopper rod bore. The attachment between the metal rod and the refractory stopper rod provides increased strength, while minimizing gas leakage and air infiltration compared to prior stopper rod attachment configurations.
