八○年为引进产品,我曾去法国MG公司有色铸造厂实习考察。同期,又对里昂等三市的三个有色铸造厂进行了短期的参观访问。上述四厂规模不大,但是管理井然有序,生产效率高,工艺、技术和设施较先进,成品质量良好。 资本主义社会物竞天存。为了竞争,法国各厂有以下特点: 1.重视采用新技术,且行之有效。如近年来,铝硅系合金长效变质剂的普遍应用;铝合金熔炼用的各种覆盖剂、脱氧剂、精炼剂的应用;冷硬树脂砂造型;浇冒系统中过滤网、保温冒口、气体保护等措施;金属型用各种涂料等,都切实有效地用于
80 years to introduce products, I went to France MG non-ferrous foundry intern inspection. In the same period, short-term visits were also made to the three non-ferrous foundries in the three cities of Lyon. The above four plants are small in scale, but they are managed in an orderly manner, with high production efficiency, advanced technology, technology and facilities and good finished products. Capitalist society competes with nature. In order to compete, the French factories have the following characteristics: 1. Emphasis on the use of new technologies, and effective. In recent years, Al-Si alloy long-term deterioration agent universal application; aluminum alloy melting with a variety of coating agent, deoxidizer, refining agent application; chilled resin sand molding; , Gas protection and other measures; metal with a variety of coatings, etc., are effectively used
