Abstract: This paper presents a method for preparing metallurgical formed coke from low rank coal in high proportion. Low rank coal，semi-coke from low rank coal，bituminous coal with some binding capacity and coal asphalt are uniformly mixed and pressed into coal briquette by high-pressure pelletizing machine with linear pressure ≥200 kN/cm. The high-pressure coal briquette becomes metallurgical formed coke after dry distillation at about 1 050 ℃. The test result shows that the compressive strength of the metallurgical formed coke is more than 5 000 N，with CRI 54% and CSR 65%，which can be used as metallurgical coke.

Key words: Formed coke, Low rank coal, Coke reactivity（CRI）, Coke strength after reaction（CSR）
