为了解决目前焦炭供应不足的问题,我厂铸工车间 的化铁炉已用全煤(采用红基无烟煤)代替焦炭正式投入生产三个多月了。从试用到投入生产也经过了多次失败,但是经过一次又一次的改进,终于克服了煤的弱点,使它成为我们驯服的燃料。现在把我们几个月来的实践过程,失败及其原因、技术上的重要改进以及简单的科学分析谈一谈,供兄弟厂参考。 In order to solve the current problem of insufficient supply of coke, iron casting furnace in our factory has been put into production for more than three months instead of coke using whole coal (using red base anthracite). After many unsuccessful attempts from trial to production, over and over again improvements have finally overcome the coal weakness, making it a tamed fuel for us. Now let us talk about the practice process, the failures and their causes, the important technological improvements and the simple scientific analysis we have come to for the reference of Brother Factory.
