2.4m宽一次码烧隧道窑工艺质量控制的认识

Process quality control of 2.4m wide once-setting-firing tunnel kiln

详细分析了窑宽2.4m一次码烧隧道窑在生产中存在的问题,并从原料性能、预均化、混合料参配、陈化、挤压成型、干燥、焙烧等方面提出了有效的改进措施。

At present,in some areas,there is a“once-setting-firing”process with a width of 2.4 m.Due to the differences in raw material properties,extensive batching,product specification changes,drying chamber structure,fan selection and production scale,fired products are prone to cracks,broken bricks and increased scrap rate.At the same time,due to the early completion of the enterprise,the imperfect process links make the quality control and mea?sures in the existing production process particularly important.
