High temperature and mechanical descaling process and installation

摘要

The present invention relates to a method for water-free descaling a metallurgical product continuously processed through a hot rolling mill installation, comprising successively a reheating furnace or tunnel furnace, a roughing mill and a finishing mill, by using a metal shot blasting device, characterised in that the shot blasting device is integrated inside the hot rolling mill and in that the metallurgical product is shot blasted at a temperature greater than 1000°C.
