为了实现农业机械化的宏伟目标,作好农机具的修配,保证随到随修、不误农时,我站建造了一座铸铁炉胆的小型热风三节炉。这样,既加快了修配工作步伐,又提高了产品质量,降低了生产成本。铸件成品率由原86～90％,上升到98％以上。生产实践表明,这种熔炉具有投资少、上马快、操作简便、对炉料要求不严以及技术经 In order to achieve the grand goal of agricultural mechanization, make repairs on farm machinery and ensure that whenever it is repaired and not misbranded, I built a small, hot blast three-stage furnace for cast iron furnace. In this way, not only speed up the pace of repair work, but also improve product quality and reduce production costs. Casting yield from the original 86 ~ 90%, up to 98% or more. Production practice shows that this furnace has the advantages of low investment, quick start-up, easy operation, strict requirements on charge, and technical
