成都市第一机制砖瓦厂,为了提高瓦坯质量,在貫彻执行质量管理制度和操作规程的同时,相应地采取了一些技术措施,使瓦坯合格率由61.21%提高到94.2%。弯翘率由20～30%下降到2%以內,具体措施是: 1.改进外場的瓦坯码法摮Ы鈭鐾吲鞔a法由竖码斜放改为平码。竪碼斜放的缺点是当坯体失水收縮后,坯体之間发生松动,形成弯翘。平碼方法可以克服这个缺点,其具体做法是:当內場瓦架上的坯体水分达到11～13%时(用大姆指按不出印时)卽行下架,然后运至外場坯埂上平码鞴∩掀酱a的瓦坯每落碼17块高,坯落底下垫以托板。这样使每块瓦坯都
In order to improve the quality of slabs, Chengdu’s first mechanism brick and tile factory, while implementing the quality management system and operating procedures, has taken some technical measures accordingly, so that the qualified rate of slabs has increased from 61.21% to 94.2%. The bending rate is reduced from 20 to 30% to less than 2%. The specific measures are: 1. Improve the field blanking method. The 摮Ы鈭鐾吲鞔a method is changed from the vertical code to the flat code. The disadvantage of tilting the vertical code is that when the blank is dehydrated and shrunk, looseness occurs between the blanks, forming a bow. The flat-code method can overcome this shortcoming. Its specific approach is: when the moisture of the blank on the infield tile reaches 11 to 13% (when the thumb is not pressed for printing), it is removed and then transported to the field. The blanks on top of the stack were lifted with a height of 17 blocks per stack, and the bottoms of the blanks were placed on pallets. This way every billet is
