莱钢265m^2烧结机厚料层烧结技术

Deep-bed Sintering Process of 265m^2 Sintering Machine in Laiwu Steel

莱钢265m2烧结机采用预热混合料、强化制粒、配加0.5%蛇纹石、控制焦粉配比4.50%等措施,解决了料层透气性差、垂直烧结速度慢等问题,实现了厚度为750mm的厚料层烧结工艺,并保证了烧结矿的产量和质量,降低固体燃耗1kg/t。

By preheating mixed material, intensifying granulation, adding serpentine of 0.5% and controlling coke powder proportion of 4.5%, the 265 m2 sintering machine in Laiwu Steel realized deep-bed sintering process with the thickness of 750 mm. The poor bed permeability, slow vertical sintering speed and other problems were solved, ensuring the yield and quality of the sinter and reducing solid fuel consumption by 1 kg/t.
