在全民大搞土法煉鋼中,鼓风問題为重要的一部份,不但关系到能否煉出銅,也影响到产品質量。一般手拉风箱,操作起來劳动较强,需要劳动力多,佔一个爐子劳动力的70％以上,往往造成劳动力的紧张。各地在党的正确领导下,充分发动羣众,开动腦筋,人人发揮了鑽勁干勁,使用水力、风力、畜力以解决鼓风問題,获得了不少成績。我們使用馬拉风箱,代替人拉送风試驗煉铜。虽試驗次数不多,但一样煉出了銅,減少了大量的劳动力。我們所用馬拉风箱基本上是按冶金局设計图紙制造的,除傳动及变速輪軸下部支点用铁质和尚头外,全部用木材制造。傳动轮直徑2公尺,变速輪直徑0.5公 In all the people making great efforts in indigenous steelmaking, the issue of blasting is an important part of not only the ability to refine copper but also the quality of products. The general hand bellows, operating more labor, labor and more labor, accounting for more than 70% of a stove labor, often resulting in labor tensions. Under the correct leadership of the party, all localities have mobilized the masses and made use of their brains. All of them have achieved great success by using their energy, wind power and animal power to solve the problem of blasting. We use the horse wind bellows, instead of people pull the wind test copper smelting. Although the number of tests is small, the same copper is refined and a large amount of labor is reduced. Our used windlass is basically manufactured according to the design drawings of the Metallurgical Bureau. All iron is made of wood except the lower part of the transmission and transmission hub with iron monk head. Drive wheel diameter of 2 meters, the speed wheel diameter of 0.5 kilometers
