在电杆生产中,蒸养工序所占的时间最长,能源消耗也最大。因此,采用先进的养护工艺是大幅度节省能源、提高经济效益的有效途径。我厂先后两次改进了养护工艺:先是由内通式蒸养改为普通坑式养护,后是在学习重庆建工学院与重庆预制构件公司一厂对楼板进行“热介质定向循环养护工艺”试验的经验的基础上,又将普通坑式养护改为能进行简单自动控制的热介质定向循环养护。这两次改进分别取得了比内通式蒸养 In pole production, the steaming process takes the longest time and consumes the most energy. Therefore, adopting advanced conservation techniques is an effective way to greatly save energy and increase economic efficiency. I plant has improved the conservation process twice: first from the common formula steamed to ordinary pit type conservation, and later in the study of Chongqing Construction Engineering College and Chongqing Prefabricated Factory No. 1 plant on the floor of the “heat medium orientation cycle maintenance process” On the basis of the experience of the experiment, the ordinary pit conservation was changed to the maintenance of a simple, automatic control of the hot medium orientation cycle. These two improvements have respectively achieved the internal steam curing
