Yüksek fırın granüle cürufunun sert kaplama uygulanmış ve uygulanmamış çeliklere karşı erozif aşındırma davranışının incelenmesi

Abstract

Three type of materails are compared in terms of slurry erosion behaviour  W2C-NiCrBSi based coating showed best resistance  Concentration of erodent particle was found dominant on the other parameters One of the biggest problems in industrial plants is wear that directly affects equipment life. In integrated plants such as blast furnaces, many types of wear are encountered, one of which is erosive wear. This type of wear is often encountered during the transport of materials with certain particle sizes. Slurry erosion is one of the most effective types of erosive wear. Granulated blast furnace slag, is essentially a waste but as a secondary product, be used in different branches of the industry. During the transfer of the slag into the liquid medium, the transport equipment is exposed to slurry erosion. The high amount of erosion seriously shortens the life of the equipment where the transportation is carried out and increases the maintenance-repair costs. In this study, blast furnace slag was used in the slurry erosive wear test system and the abrasivity of the St 37-2 reference standard pipe material, Hardox 400 and W2C-NiCrBSi coating materials was investigated.
