Abstract

PURPOSE:To prevent the deformation and breakage of a Pt film on the periphery of a metallic rod due to molten glass by dividing the metallic rod in a molten glass jig obtained by forming a Pt film on the periphery of the metallic rod into plural sections, placing a Pt sheet between the connecting parts, and welding the Pt sheet to the Pt film. CONSTITUTION:The molten glass agitating jig is formed with plural columns 10 made of Mo, each column 10 is coated with a film 11 of Pt of Pt alloy, on the periphery, a tapped hole 13 and a screw 14 are provided to the split surfaces 12 to join the columns 10, and the columns are fixed and joined by the tapped hole 13 and screw. In this case, a disk 16 made of Pt or Pt alloy and having the same diameter as the column is placed between the joining parts of the columns 10 to closely attach the disk to the column with the screw 14 and tapped hole 13, and the column are integrally bonded by the Pt film 11 and a weld zone 17. An impeller 18 of Pt or Pt alloy is fixed to the outside of the column 10 to agitate molten glass. Since the film 11 is welded to the disk 16, the film 11 is not deformed and broken by the columnar agitation of viscous molten glass.

A Pt disk 16.27 is sandwiched between the cylindrical portions 10.20 and 20, and is integrated with the cylindrical portion 10.20. Since the Pt coating 11.21 formed on the outer peripheral surface of 20 is welded and integrally reinforced, when the stirring rod for glass melting rotates and moves up and down in the molten glass to stir the molten glass, Resistance occurs between the Pt coating 11 and the molten glass,
Further, when the glass extrusion plunger moves up and down in the molten glass to extrude the molten glass, resistance is generated between the Pt coating 21 and the molten glass, and the coating IL 21 is pushed to the cylindrical part 1.
A force is generated that separates the film from 0.20, but the film 11.2

(Effects of the Invention) As can be seen from the above explanation, the glass manufacturing jig of the present invention has
A disk of Pt or Pt alloy is sandwiched between the divided cylindrical parts of a stirring rod for glass melting, a plunger for glass extrusion, etc., and is integrated with the cylindrical part. Since the Pt or Pt alloy coating on the outer circumferential surface of the columnar part is welded to the disc and is integrally reinforced,
As the stirring rod rotates and moves up and down in the molten glass, and the plunger moves up and down in the molten glass, resistance is created between the Pt or Pt alloy coating and the molten glass, and the coating is separated from the cylindrical part. Even if such a force is generated, the coating will not be twisted and damaged, nor will it be stretched or deformed. Therefore, there is no need to increase the film thickness to maintain the strength of the film as in the past, but rather the film can be made thinner because the film is reinforced, and the durability of the stirring rod and plunger is improved, resulting in a longer service life. increases.
