一向被认为还元性不强,只能化铁的冲天炉,也能以矿厂炼出灰口铸铁。这不但能解决铸铁车间生铁原料的供应不足,而且也给炼铁开劈了一条新的这路。冲天炉的构造简单轻便,只要有鼓风设备,其他设备完全可以因陋就简就地取材,建造上很容易。用它来生产对于炼铁的遍地开花,提供出有利的条件,对于生铁产量的增加,也是一个新的力量。 以下是根倨我们已经作过的四次试验的结果,按照进行的原始情况,作出初步的归纳。
Has always been considered the yuan is not strong, only the iron cupola, but also to mill out of gray cast iron. This will not only solve the shortage of pig iron raw material supply in the cast iron workshop, but also open up a new road to ironmaking. Cupola simple and lightweight structure, as long as there is a blast equipment, other equipment simply because of the simple local materials, construction is easy. Use it to produce flowers for iron everywhere, to provide favorable conditions for the increase of pig iron production, but also a new force. The following is a summary of the four tests we have made, based on the original situation.
