在“鞍钢宪法”的指引下,我厂铸铁冲水爆经过多次反复实验,解决了铸件水爆裂纹的关键问题,于1968年正式投产。采用水爆清砂,消除了危害工人健康的粉尘,减少了铸造行业工人职业病的发生,大大地减轻了工人的体力劳动,工作效率提高30多倍,促进了生产。 一、总结经验,摸索规律 水爆 Under the guidance of the “Anshan Iron and Steel Constitution”, the repeated blasting of the cast iron blasting water in our factory solved the key problems of casting water burst cracks and was formally put into operation in 1968. The use of water blasting sand removes the dust that is harmful to the health of workers, reduces the occurrence of occupational diseases in the foundry industry, greatly reduces the worker’s physical labor, increases work efficiency by more than 30 times, and promotes production. First, sum up experience, explore the law
