The results showed that the influence on the quality of the coke was little when amount of DBF was less than 0.25% and particle size was from 0.5 mm to 1 mm, but the quality of the coke decreased obviously when addition amount was more than 0.25% and the size was larger than 1 mm.
Proximate analysis, caking index and gelatin layer index were referring to the standard GB/T 212-2001, GB/T 5447-1997 and GB/T 479-2000, respectively.
The experimental results were given in Table.1 and Table.2,respectively.
Table 1 and Table 2 presented that the iron content (Fe2O3) was 71.2 wt% and there was enough carbon (FCad , 18.59) in the DBF.

DIC method is a kind of photometric test method which can quantitative analysis the full range displacement and strain of the specimen[1].
DIC system is mainly consists of CCD camera, constant light source, 1394 data acquisition card and computer that install image acquisition software (Fig.1), accessories is for fixed installation and data transmission device, such as tripod, beams, data transmission, etc.
