MULTISERIATE PULVERIZED BODY COMPRESSION FILLING METHOD CAPABLE OF PREVENTING CRACKS ON CRUCIBLES IN A COMBINING PROCESS OF SCREW FEEDERS AND CRUCIBLES

摘要

PURPOSE: A multiseriate pulverized body compression filling method is provided to increase filling velocity and filling rate in a filling process for a plurality of crucibles by developing an automatic filling device using 3x3 multiple screw feeders.;CONSTITUTION: A multiseriate pulverized body compression filling method comprises the following steps: storing pulverized body stored in a hopper to be dispersed into a screw feeder; opening a crucible cover after moving the crucible to the filling position and adhering a discharge unit of the screw feeder to an input part of the crucible; operating the screw feeder by operating a T/Q motor and progressing the filling process on the crucible; compressing the pulverized body by operating the screw feeder if the pulverized body is injected into the crucible with a certain amount; and the screw feeder is increased when the filling is completed as much as the target amount and placing the crucible into a furnace after covering the crucible cover. The screw feeders are arranged in a 3x3 form and fill the crucible bodies into 9 crucibles at once.;COPYRIGHT KIPO 2013;[Reference numerals] (1) Descend a feeder; (2) Fill with powder using the feeder; (3) Continuously fill with powder under pressure by continuously injecting while the position of the feeder is maintained; (4) Ascend the feeder after completion; (AA) Filling flow
