Research of yields of roofing tile

粘土瓦の生産技術の改善

Research overview:
Generation of defective clay roof tile is reducing regarding conventional tile, however, regarding flat roof tile which is a new product recently developed, due to the problem in production technique such that there are long distance for the transition of soil at pressing process and a big variety in the thickness, we can not say yield is in good condition. So, in order to search for the cause of occurrence of the defect, we investigate the yield in the forming process, drying process and firing process, and analyze the factor of the causes in each process for the improvement of the yield.
