Abstract

Elektrik arkli firin tozu gibi demir açisindan zengin malzemelerin atik ürünleri, briketler ve/veya diger kati kaliplar gibi ayrik kaliplarla olusturulmaktadir.Kaliplar demir ve çelik üretim proseslerinde ve agir metallerin atik ürünlerinin geri kazanilmis olarak degerlendirilmesinde kullanilabilir.Waste products of iron-rich materials such as electric arc furnace powder are formed with separate molds such as briquettes and / or other solid molds. Molds can be used in iron and steel production processes and recycled waste products of heavy metals.
