1958年是工农業生产大躍进的一年。在以鋼力綱全面躍进的带动下,各个工業部門都向前大大發展了。鑄造生产也和其他生产部门一样,出現了史无前例的大躍进局面。各厂的鑄造車間在党委的正确领导下,大搞群众性技术革新运动,并貫徹了土洋结合的方针和兩参一改三結合的工業宪法,使产量成倍地以至几倍地增長。这对满足机械工業和其他工業部門的需要,起了很大作用。随着各厂鑄工車間产量的增加,車間單位面积指标也有很大提高,鑄件成本也随之降低。工厂設計是基本建設的关鍵。由于工業的飞躍發展,給設計工作者提出了更高的要求。在设計中所采 1958 was a year of great leap forward in industrial and agricultural production. Thanks to the full-scale leap forward with the steel industry, various industrial sectors have been greatly advanced. Casting production, like other production sectors, has seen an unprecedented leap forward. Under the correct leadership of the party committee, the foundry workshops of each factory vigorously engaged in mass technical innovation campaigns, and implemented a policy of combining civil and foreign resources and an industrial constitution in which the two-incorporated and the three-incorporated one were combined. This allowed the output to grow exponentially to several times. This has played a big role in meeting the needs of the machinery industry and other industrial sectors. With the increase of the output of the cast shop of each factory, the unit area index of the workshop has also been greatly improved, and the casting cost has also been reduced. Factory design is the key to basic construction. Due to the rapid development of industry, higher demands are placed on design workers. In the design
