are metals which contain iron. They may have small amounts of other metals or other elements added‚ to give the required properties. All ferrous metals are magnetic and give little resistance to corrosion. Example: Wild steel‚ Carbon steel‚ Cast iron‚ Wrought iron‚ Stainless steel [pic] [pic] [pic] Stainless steel carbon steel cast iron • NON-FERROUS METAL

Chemistry Report – How does Galvanizing prevent Rusting? Galvanization is the process of applying a protective zinc layer of coating to steel or iron to prevent rusting. The most common form of galvanization is hot-dip galvanization. Hot-dip galvanization is the process of coating iron or steel‚ which are less reactive‚ by passing the metal via a molten bath of zinc at high temperatures. Hence‚ when the solution gets exposed to the atmosphere‚ pure zinc reacts with oxygen to form zinc oxide

has. Large proportion and large size steel balls should be added to grind high hardness and dense structure mines. To effectively grind the small mines‚ large amount of small balls are needed to increase the ball hit number in unit time. Steel iron ball is the grinding medium of ball mill and functions by collision between ball mill and steel ball‚ steel ball and materials. According to the different ball casting technology‚ different materials can be chosen. In domestic and abroad production

inventions. One of the good things about the industrial revolution was‚ that they figured out how to melt more iron more quickly and more efficient than before‚ which led to the creation of a mass of machinery created in the years following. Those machines made it possible to produce more Iron‚ from which they could construct iron bridges‚ and soon to be followed train-tracks made out of pure iron. Because of this discovery‚ both the poor and the rich could travel throughout the country for a rather small

pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that compose them. We also calculated the percent errors between the actual densities and the expected densities. The actual density of aluminum was 2.76g/cc with the percent error being 2.67%. The actual density of iron was 7.88g/cc with the percent

Dolomite mining is vital for business. Dolomite is type of carbonate mineral which incorporates iron dolomite and manganese dolomite. Dolomite may be the major mineral part made up of dolomite and dolomite limestone. The dolomite may be used in building elements‚ porcelain‚ glass and refractory after dolomite crushing. In chemical field small crusher‚ agriculture‚ environmental security‚ energy conservation‚ and so on. Therefore‚ the dolomite crusher is broadly used. The dolomite is especially utilizable

The Iron Heel- Jack London The book I read titled The Iron Heel by Jack London was written as a dystopian novel. A dystopian has the opposite of what one would expect in a Utopian society. This as I see it means that what could have been a society of happiness and leisure was turned into a horrible and oppressive government. The middle class were used and bankrupted. People such as farmers were turned in serfs. This was a portrait of what might be to come from an oligarchy type of government

Mass of Zinc Determination on Galvanized Nails Introduction. In this experiment the mass of zinc on galvanized iron nails was calculated to determine the appropriate price that should be charged to coat a nail with zinc (galvanize) it. The effectiveness of gasometric and gravimetric analysis were assessed by carrying out both methods mathematically using values determined by this experiment‚ and then comparing these values using their percent differences. The mass of zinc found on each nail can
