652厂鑄工車間(以下簡称“本車間’)是苏联給我們設計的。全部是現代化設备,地下、地面、及空中都用机械化运輸設备相联結,使大部分惡劣条件下的繁重体力劳动,均被机械所代替。由于这一工厂的建立,使我們設計工作者得一实地观摩的場地,对今后机械化鑄工車間之設計,有其極宝貴的参考价值。本車間开工生产已有年余,我于本年初得一实習机会,在此停留数月,在与各方接触中,曾就設計中若干問題,进行商討,为了更好地了解本車間,特选擇一些較重要問題,提出研討并以管見所及略加申述,希各同行指正。一制型材料的准备及砂处理部分 1.新砂的烘干与过篩問題 本車間的原設計中,新砂需經干燥(也设有不必烘
The 652 Factory Casting Workshop (hereinafter referred to as “the workshop”) was designed by us in the USSR, and all of them are modern equipments. Underground, ground, and air are all connected by mechanized transportation equipment, making most of the harsh conditions The heavy physical labor was replaced by machinery, and because of the establishment of this factory, the design workers were given a site to observe on the ground, which has extremely valuable reference value for the design of the mechanized foundry workshop in the future. For more than a year, I had an internship opportunity at the beginning of this year. I stayed here for several months. During my contact with all parties, I had discussions on certain issues in the design. In order to better understand the workshop, I selected some Important issues, presented the discussion, and made a few comments on what they saw, with the help of the company’s counterparts.1 Preparation and sand treatment of a molding material 1. Drying and sieving of new sand In the original design of the workshop, the new sand should be dried. (There is also no need to bake
