隧道窑是粘土砖烧成窑中最完善的一种类型。隧道窑是一种机械化和生产率高的设备,它能满足近代生产的基本要求。因此,还在战前,在设计新的粘土砖工厂时,就已采用它来代替轮窑了。在旧的车间内,由于面积和设计的限制,不可能放下一条长达113到150公尺的一般的隧道窑,在任何一座轮窑所占的地基上,只能放下一条很短的隧道窑。耐火材料厂中现有隧道窑的长度均是根据粘土砖在窑内烧成周期(包括预热,烧成和冷却)的长短而确定的;一个周期约为100小时。以斯大林命名的马格尼托哥尔斯克钢铁公司耐火材料车间的倒焰窑的操作实例证明:有可能缩短烧成 Tunnel kiln is the most complete type of clay brick firing kiln. Tunnel kilns are a mechanized and productive equipment that meets the basic requirements of modern production. Therefore, before the war, when designing a new clay brick factory, it had been used instead of a wheelhouse. In the old workshop, it is impossible to lay down a general tunnel kiln of 113-150 meters due to area and design restrictions. Only a short tunnel kiln can be laid down on the foundations of any one kiln . The length of existing tunnel kilns in a refractories plant is based on the length of the firing cycle (including preheating, firing and cooling) of the clay bricks in the kiln; one cycle is about 100 hours. An example of the operation of the inverted kiln in the refractory shop of the Magnitogorsk Steel named after Stalin proved that it is possible to shorten the firing
