    • Since oxidation loss can be reduced even if collected printing plates are directly melted together with fresh ingots, a high melting yield approximately equal to a melting yield in the case of melting recycled ingots can be obtained. The present invention is a melting method for melting collected printing plates 35 and fresh ingots 37 by a burner 19 in a melting furnace 13, the collected printing plates 35 being collected used lithographic printing plates 36 and/or scraps 33 including offcuts of lithographic printing plates, the method including a first injection step of firstly injecting the collected printing plates 35 in the melting furnace 13 such that a pile of the collected printing plates 35 is formed on a hearth 13B of the melting furnace 13, and a second injection step of injecting the fresh ingots 37 on the pile of the collected printing plates 35 so as not to substantially expose the pile, wherein the fresh ingots are melted in flames of the burner.
    • 由于即使收集的印版与新鲜锭直接熔融一起,也可以降低氧化损失,所以可获得大约等于在再循环锭熔化的情况下的熔融产量的高熔融产率。 本发明是一种通过熔化炉13中的燃烧器19对收集的印版35和新鲜锭37进行熔化的熔化方法,所收集的印版35被收集使用的平版印刷版36和/或废片33,包括平版印刷版的切口 该方法包括:第一注入步骤,首先将收集的印版35注入熔化炉13中,使得在熔炉13的炉膛13B上形成一堆收集的印版35,以及第二注射步骤 在收集的印版35的绒头上的新鲜锭37,以便基本不暴露绒头,其中新鲜锭在燃烧器的火焰中熔化。
