我厂是在一九六○年大跃进的凯歌声中建成的,是在土法上马的基础上不断发展、巩固、提高的。生产初期,制备混合料仅用拌合机,没有用轮碾机进行活化,成品抗压强度只达30～50Kg/cm~2。另一方面成型的砖坯靠自然干燥后再进入养护室蒸养,外观受影响,生产周期长,效率低。 Our factory was built in the great singing of the Great Leap Forward in 1960, and it is continuously developed, consolidated, and improved on the basis of the indigenous methods. In the early stage of production, the preparation mixture was only used in the mixing machine and was not activated by the roller mill. The compressive strength of the finished product reached only 30-50 Kg/cm-2. On the other hand, the formed brick slab is naturally dried and then steamed into the curing room, the appearance is affected, the production cycle is long, and the efficiency is low.
