我們車间的产品全是精密的机器鑄件,因此80％的砂型都要經过烘干,随着生产任务的增加,现有的烘窑設备已經不能滿足生产的需要,經过車間同志們研究并学習了兄弟厂的經驗,設計了一座地坑式烘干窑。地坑式烘干窑構造如圖1,窑頂是用鉄板焊成如圖2共兩塊,爐門兩边安有导軌,爐門可以按导軌用吊車吊起或者放下。这座烘干窑从設計到建成一共只有十天,投入生产后效果很好,每天平均增产10～12吨,裝窑系数最大量为烘窑的80％左右。地坑式烘干窑的特点: The products of our workshop are all precision machine castings, so 80% of the sand molds must be dried. With the increase of production tasks, the existing drying kiln equipment can no longer meet the needs of production, after the workshop comrades Researched and studied the experience of the brother factory and designed a pit-type drying kiln. Ground pit kiln structure shown in Figure 1, the top of the kiln is welded with a sampan plate as shown in Figure 2, a total of two, furnace doors on both sides of a rail, the furnace door can be lifted or lowered by crane. The drying kiln has only a total of ten days from design to completion. After putting into production, the drying kiln works well. The average daily output increases by 10 to 12 tons, and the maximum amount of kiln loading factor is about 80% of the drying kiln. Pit kiln drying features:
