我厂脊瓦坯的生产,原来是采取“众”形碼架形式(見图)室內碼架,干燥4—5天后,脫板上埂干燥。这种碼法占用地面大,設备利用率低,干燥不均匀,并由于瓦坯是斜立着,重力下压,瓦坯小头的弓頂裂縫达90%左右,需要进行修整,費工又影响脊瓦坯的质量。我們改用平瓦架生产脊瓦坯,采取露天晾架干燥后,瓦坯从出机到进窑焙燒的整个干燥过程,在正常气候情况下,仅用十天时間,損耗率2%左右,并完全消除了小头弓頂的裂縫,从而提高了瓦坯的质量。其具体操作如下: 一、碼架:(1)将出机的脊瓦坏一块块的平放,每块之間保持20—22厘米間隙。第二
The production of ridge blanks in our factory was originally taken in the form of a “public” code rack (see figure). The code rack was dry for 4-5 days and then removed from the board. This code method occupies a large surface area, low equipment utilization, and uneven drying, and due to the fact that the billet is obliquely erected, the pressure is lowered by gravity, and the crack at the bow top of the billet is about 90%, and it needs to be repaired. It also affects the quality of the ridge blanks. We used the flat-tile to produce the ridge blanks. After drying in the open air drying rack, the entire drying process of the blanks from the machine to the roasting in the kiln was under normal weather conditions. In only ten days, the loss rate was about 2%. And completely eliminate the cracks in the bow of the small head, thereby improving the quality of the billet. The specific operation is as follows: 1. Code rack: (1) Place the ridges of the machine that are out of the machine to be placed flat, with a gap of 20-22 cm between each block. second
