PLATINUM COATING REFRACTORY, TUBE GLASS MANUFACTURING DEVICE AND MANUFACTURING METHOD OF PLATINUM COATING REFRACTORY
To provide a platinum coating refractory capable of improving adhesion strength between a refractory base material and a platinum coating, a tube glass manufacturing device and a manufacturing method of the platinum coating refractory.SOLUTION: An upper wall 43 of a muffle furnace 40 comprises an upper wall body 431 as a refractory base material having ceramic particles as an aggregate and a platinum coating 432 which is a sprayed film covering the upper wall body 431. In lower surfaces 43a and 43b of the upper wall body 431 covered by the platinum covering, a ratio occupied by the aggregate having a particle size equal to or greater than 800 μm is equal to or less than 10% in a particle size distribution of reference area per unit area.SELECTED DRAWING: Figure 2
【課題】耐火物基材と白金被膜との密着強度を高めることができる白金被覆耐火物及び管ガラス製造装置及び白金被覆耐火物の製造方法を提供する。【解決手段】マッフル炉４０の上壁４３は、セラミック粒子を骨材とする耐火物基材としての上壁本体４３１と、上壁本体４３１を被覆する溶射膜である白金被膜４３２と、を備える。白金被膜に被覆される上壁本体４３１の下面４３ａ，４３ｂは、単位面積あたりの面積基準の粒子径分布において、粒子径が８００μｍ以上の骨材が占める割合が１０％以下である。【選択図】図２
