Slags (爐碴種類)

CNS 15310
鋼爐碴(steel slag)為非金屬產品, 係與鋼同時在轉爐或電弧爐之煉鋼爐中所產生, 主要為氧化鐵、氧化鋁、氧化錳、氧化鈣、氧化鎂及氧化矽等氧化物熔融組合而成之矽酸鹽及鐵
氧化物, 包含轉爐石(碴)、電弧爐氧化碴、電弧爐還原碴。

高爐石: blast furnace (BF) slag, blast furnace (BF) iron slag
轉爐石: converter steel slag, basic oxygen furnace (BOF) slag, basic oxygen furnace (BOF) the steel slag 
電弧爐煉鋼之電爐石(碴), 氧化碴: oxidizing slag, electric arc furnace (EAF) slag, the electric arc furnace (EAF) steel slag 
脫硫渣: desulfurization slag, DS
還原碴: ladle furnace (LF) slag, ladle furnace (LF) basic slag, basic slag, the reducing slag, the white slag, and the secondary refining slag 

Steel-Making Methods:
(1) basic oxygen steelmaking (BOS)
(2) electric arc furnace (EAF) - including carbon steel EAF and high alloy EAF
(3) argon oxidisation decarburisation (AOD)

European Waste Catalogue (EWC) codes for steel slag are:
10.02.01 wastes from the iron and steel industry from slag processing
10.02.02 unprocessed slag waste from the iron and steel industry
