PLATE FOR SLIDING NOZZLE DEVICE, AND MANUFACTURING METHOD AND MANUFACTURING DEVICE FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2024/009837
Kind Code:
A1
Abstract:
The present invention provides: a plate for a sliding nozzle device with which it is possible to inhibit fracturing or destruction of a plate body, and apply a greater restraining force on the plate body than in a conventional multiple hoop method; and a manufacturing method and a manufacturing device for manufacturing the same. In this plate for a sliding nozzle device, in which a hoop obtained by winding a strip-shaped thin iron sheet B in a plurality of layers is installed on the outer peripheral side surface of a plate body A1 made of a refractory, the maximum compressive strain of the inner peripheral surface of an inner hole in the plate body A1, obtained by a method for using a strain gauge to measure the strain released when the hoop is cut, is 200-1500 με inclusive. This plate can be obtained using a manufacturing device provided with a tightening mechanism 3 that includes a pressing jig 31 for holding the strip-shaped thin iron sheet B while being displaced along the outer peripheral side surface of the plate body A1, so that the strip-shaped thin iron sheet B follows the outer peripheral side surface of the plate body A1 at the portion at which the strip-shaped thin iron sheet B comes into contact with the outer peripheral side surface of the plate body A1.
