The process begins by preparing the puddling furnace This involves bringing the furnace to a low temperature and then fettling it Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite this acts as a protective coating keeping the melted metal from burning through the furnace Sometimes finely pounded cinder was used instead of hematite

Jan 28, 2012 Magnetite and hematite are important oxides of iron Though there are several differences between them, the key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state Magnetite is black in colour, but hematite has

Types of iron and steel Cast iron has already been mentioned above This section deals with the types of iron and steel which are produced as a result of the steel making process Wrought iron If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron Wrought iron is quite soft and easily worked and has

However, a practical process could not be developed because of lower porosity, higher cost of raw materials, and so on In this study, a new manufacturing principle of porous iron was proposed by applying carbothermic reduction using a composite of hematite and carbonaceous material
