    • PURPOSE: An evaluation method is provided which accurately and promptly judges a degradation index of coal used in a melting furnace in the rapid temperature increasing process by introducing new factors different from a conventional degradation index. CONSTITUTION: The method for evaluating quality of coal used in a melting furnace comprises the processes of charging samples(21) of block coal or briquette into a reaction pipe(22) the inside of which is maintained to the temperature range of 600 to 1000 deg.C under an inert atmosphere; calculating LDI(linder degradation index) values through weights of samples classified by classifying samples in the reaction pipe after rotating the reaction pipe; and judging relative qualities of the block coal or briquette by comparing differences of the LDI values, wherein the LDI values are calculated by the following mathematical expression:£Mathematical Expression|LDI(%)=100s{(weight of samples of 200 mm or more/weight of total samples after reaction)+1/2xs100sx(weight of samples between 10 mm and 20 mm/weight of total samples after reaction)}.
