我厂金屬結构車間工人楊桂盛、崔洪根、咸連生、洪国荣等,为了解决电石缺乏影响生产的关键,同时考虑到桥式超重机軌道用氧炔焰切割生产效率低而且质量不好,不能滿足生产大跃进的要求,經过多次試驗研究,結果创造了电弧摩擦鋸。试验証明,电弧摩擦锯的生产效率比一般摩擦鋸高2倍,比气割炔4～5倍(見表1)。与机械切割方法比較,无論在电能或金屬的消耗上,电
In order to solve the key problem that calcium carbide lacks impact on production, Yang Guisheng, Cui Honggen, Xianlian Sheng and Hong Guorong, the workers of metal structure workshop in our factory, can not meet the needs of production due to the low production efficiency and poor quality of oxyacetylene flame cutting for bridge over- Great Leap Forward requirements, after many pilot studies, the results created arc friction saw. Experiments show that the arc friction saw production efficiency than the general high 2 times the friction saw, gas-cut alkyne 4 to 5 times (see Table 1). Compared with the mechanical cutting method, both in electricity or metal consumption, electricity
