我下决心把炼铁的原理课上成探究型的课,把高炉炼铁的生产挪到与炼钢一起作讲解。讨论设计在实验室进行炼铁的小样试验,同学们的积极性可高了。从一氧化碳还原铁矿石向两面展开,前面是一氧化碳气体的产生,后面是尾气中二氧化碳的验证和有毒的一氧化碳的处理。从反应原理到发生装置的选择,从操作顺序到可能产生现象的探讨,他们时而争论得面红耳赤,时而又高兴得哄堂大笑。经过分析讨论,不断完善,终于把实 I made up my mind to classify the principles of ironmaking into introductory classes and moved the production of blast furnace ironmaking to explain with steelmaking. Discussing the design of a sample test of iron making in the laboratory, the enthusiasm of the students can be high. The reduction of iron ore from carbon monoxide on both sides is preceded by the production of carbon monoxide gas followed by the verification of carbon dioxide in the exhaust gas and the treatment of toxic carbon monoxide. From the principle of reaction to the choice of devices, from the order of operations to the discussion of possible phenomena, they are sometimes arguing with red faces, and sometimes they are happy to laugh. After analysis and discussion, continuous improvement and finally real
