Abstract:　Research test is carried out on producing unsteaming and unfiring sintering briquette, the main material of which comes from lignits lag drained by No.2 Wollen Mill in Chifeng City, inner Mongolia. More than 50 gr oups are made. Over 450 test samples are formed. Several tests on sintering briquette’s compressivity,bendity and frost resistance are carried out. Physical and chemical element tests are conducted on the utilized material, particularly the multi-group mix proportion of brick’s compressive strength under different compressive strength circumstance is studied the function of admixture and optimum mix quantity are obtained. Through orthognal experiment, unsteaming and unfiring sintering briquette’s mix proportion and producing technology are worked out ,which has proptrties of reasonable economic btnifit, energy saving and waste material reuse. The physical and mechanic property can macth with that of common clay brick.
