华新水泥厂制造钢丝网水泥农船,目前基本上是采用手工操作。经过这两年的摸索,他们积累了一些经验,现简要介绍如下:(一)正模与反模施工反模施工比正模施工有较多的优点,可以提高质量,减轻劳动强度,提高工效。1.正模施工的优缺点:优点:A.船胎架制作比较简单。B.船壳体内表面没有二次修补的施工缝。C.壳体粉刷后不需翻身修补,可避免船体损伤。
Huaxin Cement Plant manufactures wire mesh cement ships, which are currently basically hand-operated. After two years of exploration, they have accumulated some experience and are briefly introduced as follows: (1) Positive and negative mold construction Counter-mold construction has more advantages than positive-mold construction, which can improve quality, reduce labor intensity, and improve work efficiency. . 1. The advantages and disadvantages of the construction of the positive die: Advantages: A. The production of the tire frame is relatively simple. B. There is no secondary repair of the inner surface of the ship shell. C. After the shell is painted, it is not necessary to turn over and repair, so as to avoid damage to the hull.
