METHOD AND APPARATUS FOR MELTING COLLECTED PRINTING PLATE AND METHOD FOR RECYCLING COLLECTED PRINTING PLATE
Document Type and Number:
Japanese Patent JP2011256454
Kind Code:
A
Abstract:

To obtain melting yield as high as the melting yield obtained when collected printing plates are melted with reproduced bare metal because an oxidizing loss can be reduced even when the collected printing plates are directly melted together with new bare metal.

New bare metal 37 is melted in a first melting furnace 12 so as to form molten metal 37A, and the molten metal 37A is sent to a second melting furnace 13. In addition, a vortex 39 that sinks down into the molten metal 37A of the second melting furnace 13 is formed, and collected printing plates 35 are fed into the vortex 39.
