APPARATUS FOR REMOVING SCALE FROM ROLLED PRODUCT Russian patent published in 1995 - IPC

Abstract RU 2030939 C1

FIELD: metallurgy. SUBSTANCE: apparatus has auger and housing filled with abrasive powder. When rolled product is passed through openings in auger and housing, it is cleaned from scale. Apparatus is characterized in that helical spring is used as auger for providing required compaction of powder in chamber. It allows compaction chamber dimensions to be reduced by using open spring coil spacing so that abrasive powder interacts with rolled product along the whole length of housing. Moreover, feeding of abrasive powder from receiving window into housing and entrainment of powder by auger are facilitated. EFFECT: increased efficiency in removing scale from rolled product by improved usage of spring coil spacing of compaction chamber and housing and high quality of cleaned surface. 1 dwg
