本刊1957年6月份57页刊载郭卓羣同志所写的“高中化学‘铁和它的化合物’一节中有关基本生产技术教育的教材与教学的研讨”一文,对于在中学进行这方面的教学提出了不少的宝贵的意见,由于钢铁的冶炼照例是中学教师非常重视的一个问题,因此我觉得有必要将其中某些个人认为不够妥当的地方提出来与郭同志商讨一下。1.在炼铁原料中指出“黄铁矿不能用为冶铁原料,因含硫太多”。我认为这句话讲的太绝对了些,教科书也只是说“很少应用在冶金工业方面”,固然目前黄铁矿在整个炼铁原料中所占的数量是不大的,但是也必须指出,由于近代技术的进步(将矿粉进行烧结时,可以去掉矿石中的含硫量的80%以上,操作恰当时可达到99%)和考虑到国家资源的综合利用,黄铁矿不但可以用来炼铁,而且还具有相当大的经济意义,例如我国某硫酸厂从机械焚矿炉出来的炉渣含硫3%以下,从沸腾炉出来的炉渣含硫量低至1%以下,将此矿渣烧结后,含硫量即非常微小,因此实际上,该厂的矿渣已成为炼铁的原料。
The Journal published in June 1957 57 pages published by Comrade Guo Zhuotun wrote “high school chemistry iron and its compounds’ section on basic production technology education teaching materials and teaching,” a text for high school teaching in this area A lot of valuable opinions. Since the routine smelting of steel is a problem that high school teachers attach great importance to, I think it is necessary to discuss with Comrade Guo some areas where some of them are considered inadequate. 1. In the ironmaking raw materials that “pyrite can not be used as raw materials for smelting, because too much sulfur.” I think this sentence is too absolute, and textbooks only say “rarely used in the metallurgical industry.” Although the present amount of pyrite in the whole ironmaking raw material is not large, it must also be pointed out , Due to the progress of modern technology (when the ore powder is sintered, the sulfur content in the ore can be removed by more than 80%, and the operation can reach 99% when appropriate) and considering the comprehensive utilization of national resources, the pyrite can not only be used For example, a sulfuric acid plant in our country has a sulfur content of less than 3% from the residue of a mechanical incinerator and a sulfur content of less than 1% of the slag from a boiling furnace, and the slag is sintered After the sulfur content is very small, so in fact, the plant’s slag has become the raw material for ironmaking.
