PREHEATING BURNER FOR A CYLINDER HEAD CASTING DEVICE CAPABLE OF HANDLING INITIAL CASTING PRODUCTS ACCORDING TO STANDARD WORKING CONDITIONS BY PREHEATING A MOLD AND A MELT PATH BEFORE A CASTING OPERATION

摘要

PURPOSE: A preheating burner for a cylinder head casting device is provided to enhance the density of components by ensuring the good shape or temperature distribution of the flame of a gas nozzle.;CONSTITUTION: A preheating burner for a cylinder head casting device comprises a gas pipe(110), a first gas nozzle(120), and a second gas nozzle(130). The gas pipe is inserted into the inner spaces of a mold and a melt path. The gas pipe is a transfer path for fuel gas. The first gas nozzle is formed on a part of the pipe inserted into the mold. The first gas nozzle jets fuel gas to the mold. The second gas nozzle is formed on a part of the pipe inserted into the melt path. The second gas nozzle jets fuel gas to the melt path.;COPYRIGHT KIPO 2012
