本发明公开了一种烧结用生石灰制粒效果的评价方法，该方法包括：取等量的三份生石灰；将一份生石灰通过量热仪测量所述生石灰在设定时间内的放热量Q；将一份生石灰采用毛细吸水法测量生石灰在所述设定时间内的吸水量W；将一份生石灰放入烧杯中 ，加入足量的水并搅拌，并在所述设定时间内反应后，并将反应后生成的生石灰乳烘干后的烘干物进行称量；再对筛分出的粒度小于0 .25mm的筛下物进行称量，计算所述筛下物质量与所述烘干物质量之比R；根据放热量Q、吸水量W和所述筛下物质量与所述烘干物质量之比R来计算生石灰制粒效果评价指数Lg。采用本发明的方法，对选择合适的烧结用生石灰有重要的指导意义。

The invention discloses a granulating effect of quicklime for sintering，The method includes: taking three equal parts of quicklime;A portion of quicklime is measured by a calorimeter Heat release Q within a given time; A portion of quicklime is capillary aspirated Measuring the water absorption w of quicklime within the set time by water method;Put a portion of quicklime into a beaker, add enough water and stir，After mixing and reacting within the set time, the reaction is regenerated.The dried product of the dried quicklime milk shall be weighed; Re screen. Weigh and calculate the sieved material with particle size less than 0.25mm.The ratio r of the mass of the under sieve material to the mass of the dried material; according to the heat release Q, the water absorption W and the mass under the sieve are the same as the drying. The evaluation index of quicklime granulation effect is calculated by the ratio of material mass R Lg. By adopting the method of the invention, it is important to select a suitable raw material for sintering.
