DESCALING APPARATUS

摘要

The present invention relates to a descaling apparatus for effectively removing scales formed on surfaces of hot-rolled steel strips (steel sheets). An embodiment of the descaling apparatus of the present invention comprises: a housing arranged on a hot-rolled steel strip transfer path; high pressure fluid supply means arranged in the housing to supply by injecting a high pressure fluid into the housing; abrasive material injection means arranged in the housing to inject an abrasive material into the housing; and abrasive slurry spray means arranged in the housing to spray, onto the hot-rolled steel strips, abrasive slurry of the high pressure fluid and the abrasive material mixed in the housing. According to the present invention, physical (mechanical) descaling is implemented, scale treatment processes are simplified, and surface roughness of the hot-rolled steel strips can be maintained at an appropriate level, thus enabling eco-friendly and high efficiency descaling. Particularly, the apparatus of the present invention can be applied to hot-rolled steel strip treatment process being performed at high speed.
