在十年级化学课中研究生铁与钢的生产原理。在这节课程的教学中,教师可能向学生介绍黑色冶金工业的物理化学过程的本质,阐明典型设备的构造原理,主要技术操作的内容,技术发展的主要方向。对冶金工业是国民经济的重要部门这一点,给予学生以一般概念。在这儿也可能使学生对化学工业方面的既得知识,进一步获得巩固与具体化。这样,黑色冶金工业基本知识的讲授,是化学教学过程中向学生进行综合技术教育的主要阶段。本文对生铁与钢的冶炼这一课程,不作细节研究,仅对这节教材的内容与教学方法方面,讨论几个最主要的问题。生铁的冶炼在进行鼓风炉冶炼过程的讲述前,学生应对鼓风炉原料与熔融产物,尤其是铁矿与铁合金的组成与性质,具备一定的知识。关于铁合金,学生应知道:铁有与碳、硅、锰及其他元素形成合金的性能;生铁与钢的组成,晶体结构,熔点,机械性能;各种最主要的生铁与钢。向学生讲述生铁的生产须从最主要的过程——鼓
In the tenth grade chemistry class graduate iron and steel production principle. In the teaching of this course, teachers may introduce students to the essence of the physical and chemical processes of the black metallurgical industry, clarify the construction principles of typical equipment, the contents of major technical operations, and the main directions of technological development. Metallurgical industry is an important part of the national economy, giving students a general idea. It is also possible for students to further consolidate and substantiate the acquired knowledge of the chemical industry here. In this way, the teaching of the basic knowledge of the black metallurgical industry is the main stage of comprehensive technical education for students in the process of chemistry teaching. This article on pig iron and steel smelting this course, without going into the details of the study, only the contents of this section teaching materials and teaching methods, to discuss a few of the most important issues. Smelting of pig iron Prior to telling the blast furnace smelting process, students should have some knowledge of the composition and properties of blast furnace raw materials and molten products, especially iron and iron alloys. For ferroalloys, students should know that iron has the properties of alloying with carbon, silicon, manganese and other elements; the composition, crystal structure, melting point, mechanical properties of pig iron and steel; and the most important types of pig iron and steel. Tell students about the production of pig iron from the most important process - drums
