摘要： A novel filament composed of at least one thermoplastic synthetic polymer, said filament being characterized by having (1) an irregular variation in the size of its cross section along its longitudinal direction, and (2) a coefficient of intrafilament cross-sectional area variation [CV(F)] of 0.05 to 1.0; and a novel bundle of said filament. The bundle of filament-like fibers can be produced by extruding a melt of a thermoplastic synthetic polymer through a spinneret having numerous small openings, which comprises extruding said melt from said spinneret, said spinneret having such a structure that discontinuous elevations are provided between adjacent small openings on the extruding side of the spinneret, and the melt extruded from one opening can move to and from the melt extruded from another opening adjacent thereto or vice versa through a depression existing between said elevation; and taking up the extrudates from the small openings while cooling them by supplying a cooling fluid to the extrusion surface of said spinneret or its neighborhood, whereby said extrudates are converted into numerous separated fine fibrous streams and solidified.

摘要： A refining furnace used for vacuum refining has a sealing cover mounted on the refining furnace so as to cover the furnace throat of the refining furnace and to be in close contact with a sealing flange (10) formed on the refining furnace. The adhesion of metal and slag to the sealing flange is prevented without using any flange cover. A sealing flange (10) is formed on the outer surface of the refining furnace (1) at a position on a conical part (8) extending between the furnace throat (9) and a straight body part or on the straight body part. A slag-stopping dummy flange (11) is formed on the outer surface of the refining furnace (1) at a position between a furnace throat (9) and the sealing flange (10). The slag-stopping dummy flange (11) has an outer circumference lying on the inner side of the inner circumference of a sealing cover (4) and on the outer side of the inner circumference of a lower end part of a dust collecting hood for atmospheric refining.
