烧结料在烧结初期的收缩与料层中的料粒在负压和烧结机振动作用下的压密有关,以及与料粒在点火器热辐射影响下变形和破裂有关。根据H.B.奥尔纳茨基的《土壤力学》一书所述,因料粒压密而收缩的程度取决于
The shrinkage of the sintering material in the initial stage of sintering is related to the compacting of the material particles in the material layer under negative pressure and vibration of the sintering machine, and the deformation and cracking of the material under the influence of the heat radiation from the igniter. According to H.B. Ornatski’s book Soil Mechanics, the degree of shrinkage due to particle compaction depends on
