一、概况某混凝土构件厂双向预应力楼板养护窑是在1979年初设计,于同年投产使用的。工艺提供的图纸见图1,工艺要求:两窑连续生产,制品在钢模车上成型后,送入窑内经升温、恒温与降温区养护后出窑,具体数据见表1。 I. INTRODUCTION The maintenance of a two-way prestressed floor maintenance kiln of a concrete component plant was designed in early 1979 and put into production in the same year. The drawings provided by the process are shown in Figure 1. Process requirements: Two kilns are continuously produced.
