我厂铸造车间原有的熔化设备为仿苏三排风口冲天炉,现将其改造成为倒置两排大间距冲天炉,经过半年多实践,证明其熔炼效果良好,在保证高温,优质铁水的前提下,降低了焦铁比,保证了铸件质量,大大减少了因铁水而产生的废品。现将炉子主要结构介绍如下。 The original melting equipment of our foundry was imitation su-three vents. Now it is transformed into two rows of inverted cupolas. After more than six months of practice, it proves that the smelting effect is good. Under the premise of ensuring high temperature and high quality hot metal, Under, reducing the iron-iron ratio, to ensure the quality of castings, greatly reducing the waste generated due to hot metal. Now the main structure of the stove are as follows.
