a.随着烧结料层的提高,点火时间和高温保持时间延长,表层供热充足,冷却强度降低,烧结表面强度差的烧结矿比例相应下降,成品烧结矿产量提高。b.厚料层烧结时,烧结高温带增宽矿物结晶充分,主要液相体系以铁酸钙为主,烧结矿强度和成矿率提高。c.烧结过程中,料层自动蓄热能力随料层的
a. With the increase of sintering material layer, the ignition time and the holding time of high temperature are prolonged, the heating of the surface layer is sufficient, the cooling intensity is reduced, the proportion of sinter with poor sintering surface strength is correspondingly decreased, and the output of finished sinter is increased. b. When the thick material layer is sintered, the broadening and broadening mineral crystallization in the high temperature sintering zone is sufficient. The main liquid phase system mainly consists of calcium ferrite, and the sinter strength and mineralization rate increase. c. sintering process, the material layer automatically with the ability to heat storage
