我厂在增产节约运动中,加强了轮窑烧瓦的技术管理,改进了烧瓦工艺,红瓦质量显著提高,外观光滑平整,基本消除了生泥块和孔隙等缺陷,成品率和一等品率分别达到98.61%和90.33%,混等率下降到8%左右。我厂提高轮窑烧瓦质量的主要措施是:一、改进装窑。改进前的装瓦形式是,从窑底开始为二顺坯,27个头,三行横带。炕上二顺坯28个头,再往上二行是一里一外斜码,以上开始装瓦,共装8层;不铺瓦条坯,瓦坯中不夹砖坯。瓦坯是按一直一斜的形式一层层码到窑顶。斜条方向是一里一外
In the process of increasing production and saving, our factory has strengthened the technical management of the kiln burning tile, improved the burning tile process, significantly improved the quality of the red tile, the appearance of a smooth surface, basically eliminates the defects such as the sludge block and void, the finished product rate and the first grade. The product rates reached 98.61% and 90.33% respectively, and the mixed rate dropped to about 8%. Our main measures to improve the quality of kiln firing tiles are: First, improve the kiln. The form of pre-improvement loading is to start from the bottom of the kiln for two blanks, 27 heads and three rows of cross belts. The first 28 heads of the second Shunshuang billet, and the second to the upper line are the one yard and one outer oblique code. The above starts the loading of tiles and a total of eight layers are installed; the billet is not tiled and the billet is not clipped in the billet. Tiles are layered to the top of the kiln in a diagonal form. The direction of the oblique bar is one outside and one outside
