MetalWorks is a company that produces and distributes steel file cabinets and lockable steel storage boxes, known in the Industry

As the decades went on the blacksmiths began to do more tool and vehicle repair and spent less of their time making items. Their tools can be divided into three categories, the flames, the anvil and sledge/hammer, and the some other equipment. Under the first group was the bellows, the shovels, the rake and pretty much anything else used to move the coals, and the water trough. Under the second group was the tongs, cutters and chisels, as well as hammers and anvils. In the third group was the shoeing box (which contains knives, rasps, and files) to make horses ' feet and horse shoes. They made items by first softening the metal over a flame. They then used a bellows to get the flame as hot as necessary. There are three levels of heat, snowball heat, full-welding heat, and light-welding heat. The hottest is snowball heat, which refers to white heat; is used to weld. Then there is full-welding heat, not quite as hot as snowball, employed to weld mild steel. The last is low or light-welding heat, rarely used because of how difficult it is. Then when it is hot enough the blacksmith hits it with a hammer to shape it. A blacksmith is trained as an apprentice by a more experienced blacksmith because there was no trade school. Some things that blacksmith’s construct are ploughshares, sickles, scythes, metal parts for wagons and carriages, wheel rims, tools, axe heads, hammers, shovels, hoes, pitchforks, nails, screws, bolts,

These three materials can be found almost anywhere in the world, but sometimes they can be difficult to extract from the land. Specifically, coal. Entrepreneurs trying to produce the steam engine had an excess of iron and lumber, but the coal was being burnt too quickly. This demand lead to the invention of coal coke, which burned at a slower rate than regular coal. Also, the extraction of materials like coal, iron, and lumber create more job opportunities by themselves, giving countries that have these materials stronger

Bessemer Steel Process- an improved way of making the mass production of steel (page 506)

The metal surfaces are first ground and packed which locks the metal together. Metal spacers and cladders are used to maintain a curtain space between the metals. Then a frame is used to hold the explosion powder.

The art of Blacksmithing, crafting master swords out of fire and iron, was no easy task. Blacksmiths often bought iron ore in which they melt down and add carbon, turning iron into steel. Blacksmithing has been used for thousands of years, and in the that time, blacksmiths had learned the process in which to combine the steels together to make a flexible yet strong blade. Blacksmiths had no set process for crafting steel or the weapons in which they made according to the customer’s stipulations.

Once the iron ore was obtained something had to be done with it. The iron ore was heated or roasted in a pit around 1500°C and was cover in charcoal. The process of melting iron ore was a very tricky one at that. The iron then eventually melted out of the ore. The bottom corner

The purpose of the furnace ignitor is to automatically light the pilot or burners. Your ignitor may work by spark ignition or by hot surface ignition. Hot surface ignition is the most common method when it comes to newer gas furnaces. Hot surface ignition uses a ceramic ignitor. Power supplied to your furnace than

Steel is a light element and is a lot easier to carry than wood. This being, it is easier to work with steel and to make sure you get the best use of it. When you cut a piece of wood it is very different from when you cut steel. The scrap that falls off of steel can be melted down and used to make a new steel post. when you cut off wood you can reuse it but it will not be exactly the same as the material you cut it off of, it would be plywood.

(The night an blast furnace pg 11, 12, 14) Wootz steel would be imported by Europe and also called Damascus steel.(History of Metallurgy pg

One way that this is thought to have been achieved is alternating hard bands of iron with softer more flexible bands of iron giving you the best of both worlds. Another thought is that they where made with a small amount of vanadium. This might have been what gave Damascus steel its amazing strength. now how it got the name is still a matter of opinion. Most people would think that the reason that they are called Damascus is that that is where they are made. There is a though that they might be named after that man that first made them. It is thought that the man that first made the Damascus steel is in faced named Damashqu, and that is where they got there legendary name. This steel was originally made using ore from a mine. This ore had a certain chemical composition, and well for lack of a better word this mine was mind tell it was empty, so they just ran out of the material used to make the steel. To attempt to artificially create this chemical composition would be very

Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.

Basic Oxygen Steelmaking is a primary steelmaking method, in which convert carbon-rich molten pig iron into steel due to oxidizing action. Oxygen was blown into the melt under a basic slag. It is the most powerful and effective steel making method. The converter used for steel making is called as Basic Oxygen Furnace. There is about 67% of steel in the world is produced using Basic Oxygen Steelmaking. The process of Basic Oxygen Steelmaking was developed in 1948 by Robert Durrer and commercialized in 1952-1953 by Austrian VOEST and ÖAMG. The modern furnace takes a charge of up to 350 tons iron and converts it into steel within 40 minutes.

The achieved coal is mainly composed of carbon, hydrogen and oxygen (nitrogen and sulphur being minor elements) which are combustible in nature, and it also consists of impurities (10 to 40%) existing in the form of clay, shale, quartz, feldspar and limestone. As the coal enters the furnace, the combustible elements of the coal are scalded at the elevated temperatures, whereas the mineral impurities of the coal chemically recombine to produce crystal clear parts of the molten ash. Later, the molten ash enters the flue gas and by lowering the temperature rapidly the ash turns into spherical, glassy particles. Furthermost these particles fly out along with the flue gas stream and hence the names fly ash. Finally, electrostatic precipitator collects all the fly ash
