就带式烧结机来说,从1906年世界上开始使用带式烧结机以来,到今天已有七十多年的历史了。但在五十年代以前烧结机的发展一直非常缓慢,进入六十年代以来,烧结机的发展较快,特别是进入七十年代以来,世界烧结生产和建设有了很大的发展。由于大型烧结机具有单位烧结面积基建投资少,经管费低和劳动生产率高等～系列优点。因此,进入七十年代以来,世界烧结技术发展的特点是烧结机向大型化和特大型化方向发
As far as belt sintering machines are concerned, it has been more than seventy years since the belt sintering machine started to be used in the world in 1906. However, the development of sintering machines until the 1950s has been very slow. Since the 1960s, the development of sintering machines has been developing rapidly. Especially since the 1970s, there has been a great development in world sintering production and construction. As a result of large-scale sinter sintering unit area less capital investment, low management costs and high labor productivity ~ series of advantages. Therefore, since the 1970s, the development of sintering technology in the world has been characterized by its large size and large size
