Abstract
PURPOSE: To extremely easily perform surface defect removing pretreatment of billets by performing burr through automatically forming a scarfing groove at the end part of hot billet.
CONSTITUTION: Hot billet 5 from the cutter is sent to the fixed location of table roller 11. The scarfing groove 9 is formed on shear drop surface 6 of billet 5 with torch 12 of the scarfing machine 4, and the marginal parts of both sides of this scarfing groove 9 become the burrs 10. This work is extremely easy and the working efficiency is improved considerably.
