摘要： An apparatus for treating a molten metal comprises a vertical post, a treating container disposed at one side of the post and having an opening at its upper end for containing the molten metal, a horizontal suspending arm mounted at its base end on the post upwardly and downwardly movably and rotatable in a horizontal plane, a vertical rotary shaft suspended from the arm and having a treating gas channel internally extending therethrough longitudinally, a bubble releasing-dispersing rotor provided at the lower end of the rotary shaft and having in its bottom surface a treating gas outlet in communication with the gas channel, the rotor being movable into and out of the container through the opening, and at least one baffle suspended from the arm and movable into and out of the container through the opening for preventing eddying and waving. When there arises a need to repair or relace the rotary shaft, the rotor and/or the baffle, or when the dross is to be removed from the surface of molten metal after the treatment, the rotor, the shaft and the baffle are brought out of the container by raising the suspending arm and are thereafter brought to a position away from immediately above the container by horizontally moving the arm. The above work is then performed.

摘要： A metal having a high purity is prepared by immersing a hollow rotary cooling member in a molten metal containing eutectic impurities and rotating the cooling member while supplying a cooling fluid to the interior of the cooling member, whereby the high-purity metal is caused to crystallize out on a metal deposition area of the peripheral surface portion of the cooling member present under the surface of the molten metal, the metal deposition area being the peripheral surface of at least a part of the entire portion, present under the melt surface, of the member. When the purified metal is caused to crystallize out by rotating the cooling member, a flow of molten metal having a downward velocity component is produced in the vicinity of an upper part of the entire portion, present under the melt surface, of the cooling member.

摘要： A device comprising a rotary shaft to be disposed in a liquid substantially vertically and rotatable about its own axis, the rotary shaft having a gas channel extending therethrough axially of the shaft, and a rotor fixed to the lower end of the rotary shaft and having at its bottom surface a gas discharge outlet communicating with the gas channel. The rotor is formed in its bottom surface with radial grooves extending from the gas outlet to the peripheral surface of the rotor and each having an open end at the peripheral surface. A recess is formed in the peripheral surface between the open ends of immediately adjacent grooves and has an open lower end at the bottom surface. When the rotary shaft is rotated in a liquid while supplying a gas to the gas channel of the shaft, the gas flows out from the discharge outlet into the radial grooves and is released from the open ends of the grooves at the peripheral surface into the liquid in the form of finely divided bubbles. The bubbles are diffused through the entire body of the liquid by the liquid flowing in the centrifugal direction while revolving in the same direction as the rotor owing to the agitating action of the recesses in the rotor peripheral surface.
