ISO标准下提高立窑熟料强度的研究与生产试验

Research on Improving the Strength of Clinker Made by Vertical Kiln

针对采用ＩＳＯ标准后，立窑熟料强度大幅下降的现状，通过采用高硅高铝配料，并在 φ ３ｍ×１１ｍ机立窑上采取相应措施强化煅烧，使立窑熟料２８天ＩＳＯ抗压强度由 ４３．３ ＭＰａ提高到 ５４．６ＭＰａ，达到ＩＳＯ贯标的要求。

With the implementation of ISO strength standard, the strength of clinker made by vertical kiln has great descendant. To resolve it, raw mixes with high SM and high IM are adopted and experiment is carried out on φ 3m × 11m vertical kiln. It is proved by experiment that the 28d compressive strength of clinker can be improved from 43.3 MPa to 54.6 MPa on ISO strength standard.
