Beschreibung
Zusammenfassung:	[Problem] To make it easier to prvent adhesion of foreign matter to the surface of a steel sheet transportation roll. [Solution] A steel sheet transportation roll according to the present invention has a thermal spray coating located on the surface of the transportation roll substrate, and an abradable coating located on the surface of the thermal spray coating, the abradable coating containing polysiloxane as well as zirconia particles, boron nitride particles, and colloidal particles dispersed in the polysiloxane. L'invention vise à éviter l'adhérence de matière étrangère à la surface d'un rouleau de transport de tôle d'acier. À cet effet, un rouleau de transport de tôle d'acier selon la présente invention comporte un revêtement de pulvérisation thermique situé sur la surface du substrat de rouleau de transport, et un revêtement abradable situé sur la surface du revêtement de pulvérisation thermique, le revêtement abradable contenant du polysiloxane ainsi que des particules de zircone, des particules de nitrure de bore et des particules colloïdales dispersées dans le polysiloxane. 【課題】鋼板の搬送用ロール表面への異物の付着をより容易に防止すること。【解決手段】本発明に係る鋼板の搬送用ロールは、搬送用ロール基材の表面に位置する溶射皮膜と、溶射皮膜の表面に位置するアブレイダブル皮膜と、を有しており、アブレイダブル皮膜は、ポリシロキサンと、当該ポリシロキサン中に分散しているジルコニア粒子、窒化ホウ素粒子及びコロイダル粒子と、を含有する。
