摘要： PURPOSE: To surely discharge a molten metal zone easily solidified through a flowing passage at the tapping time by enlarging the flowing cross section of the flowing passage from a flowing inlet of the molten metal to a flowing outlet. CONSTITUTION: In a closing device for metallurgical molten metal vessel, in which a refractory outer tube 4 and a refractory inner tube 5 supported in this outer tube are provided, and the outer tube and the inner tube are provided respectively with at least one of closing hole 9, 11. Either one of the tubes is shiftable from the closing position to the flowing position in relation to the other tube, and these closing holes exist in the flowing passage 7 extended from the flowing inlet to the flowing outlet 12 at the rear part of the closing holes in the inner tube in view of the flowing direction. The flowing cross section of the flowing passage has such feature as to gradually enlarge from the flowing inlet to the flowing outlet.

摘要： PURPOSE: To increase the quantity of heat supplied to a material to be heated by reducing the direct reflection of radiant heat by forming the wall surfaces of a depression, in such a way that the radiant heat from one wall surface comes into collision with the other wall surface and, in addition, is absorbed into a lining brick. CONSTITUTION: Each lining brick 1 has a plurality of notches 2 open onto the internal space 4 of a furnace. The bricks 1 are assembled in such a way that the adjacent two notches 3 of each adjacent bricks 1 form a depression 5 which opens onto the internal space 4 of the furnace in an opened cross section A. The depression 5 has side walls 7 continuously formed from a bottom 6 which is formed in such a way that the radiant heat which comes into collision with the bottom 6 from the internal space 4 is reflected to the side walls 7 and absorbed into the side walls 7. Since most of the heat is reflected by the lining bricks 1 in the depression 1 in such a way, the direct reflection of the radiant heat to the internal space 4 of the furnace is reduced. Therefore, the heat absorbed into the lining bricks 1 is discharged into the internal space 4 and effectively supplied to a material to be heated.

摘要： PURPOSE: To reduce a total energy demand by executing a heat treatment and preheating at a place of use by a heater at the time of producing a high-temp. shaped ceramic part. CONSTITUTION: At the time of producing the shaped ceramic part for a high- temp. range particularly with a continuous casting apparatus, the heat treatment is executed at least partly in the place of use of the shaped part by the heater and the preheating of the shaped part is executed in the place of use by this heater. As a result, there is no need for cooling the shaped part between the heat treatment belonging to production and the advantageous heating in operation in the place of use. The total energy demand is thus considerably decreased and the use of a material liable to be affected by a temp. change is made possible.

摘要： PURPOSE: To eliminate risk of molten breakthrough due to cracking of a inner pipe by determining the closing stroke of an outer pipe such that the lower end thereof is mounted on an annular plane extending around the inner pipe without causing any leakage. CONSTITUTION: Opening 5 of an inner pipe 2 is aligned with the opening 7 of an outer pipe 3 at open position. Molten flow from a vessel is changed by turning or moving the outer pipe 3. When emergency shutoff is required in order to prevent molten breakthrough, the outer pipe 3 is moved quickly in the direction of longitudinal axis until the edge 8 thereof abuts against an annular plane 10. The outer pipe 3 does not abut against the upper edge of the inner pipe 2. Since the edge 8 of the outer pipe is mounted on the annular plane, a hermetically sealed region is formed additionally. The outer pipe 3 covers the opening 5 of the inner pipe 2 and surrounds the entire length thereof projecting into a vessel. This structure prevents flow-out of molten even if the inner pipe 2 is damaged or cracked.
