When heat is applied to an object, that object usually undergoes a structural change. This also applies to rock. Since Knife River Flint is a fine-grained stone the changes predictably would be minor, compared to a coarse-gained stone that would exhibit greater change when it came to thermal altering. Ahler purposed “that fine-grained cherts respond to heat alteration at lower temperatures than do coarse-grained cherts” (Ahler 1983: 2) which Knife River Flint is a fine-grained chert, so it…

ranks at the company until becoming the secretary for the superintendent. His many trips to England brought his eye to steel which would later become an essential product for cities to grow. He created his own steel company in 1872 in the U.S. which made steel using the Bessemer steelmaking process from England which made steel efficiently allowing his company to expand. Carnegie’s steel company…

Industrialization in America could not have been achieved with a few key factors. Among these are the rich environment in America, a sympathetic and supportive government that remains deferential to private ownership, talented business leaders, railroads, and technology. The mineral deposits in the land as well as the presence of business visionaries like Andrew Carnegie were equally important in the overarching success of the American Industrial Revolution. Andrew Carnegie’s ability to…

Abstract Thermo-mechanic treatment consists in utilization of two classic technological proceedings. This type of treatment was applied to the studied high-speed steel (HS2-9-1-8). The made tests wanted to establish the influence on the hardness and wear of the high-temperature thermo-mechanical treatment (HTTMT) applied to studied steel. The application of an additional plastic deformation (the deformation degree between 45 – 75%) influences positive the hardness and wear value. Being a HTTMT,…

1. Introduction Mining is the extraction of minerals from the earth surface that are of economic value, extraction is done by people and machines. While mechanisation is expensive and reliable it also has limitation. Employment of men only in the mining industry was seen as an inequality which led to women taking part in the mining industry. Although historical analysis had the perception that women are not fit enough to go underground and laws were passed on to support the exclusion of women…

1.0 Introduction A wire is defined as a single, flexible strand or rod of metal which is typically cylindrically-shaped. The core applications of wire, both single- or multi-stranded wire, are to withstand or carry mechanical loads in construction sector, whereas in electrical and electronic field are used to transmit electricity and telecommunications signals. For examples, from view of construction, wires are either braided or fixated together to form a bundle of strands, namely…

Performance Evaluation: NIPPON STEEL & SUMITOMO METAL CORPORATION (NSSMC) is a joint venture based in Tokyo (Japan) and as the name implies, it produces steel in high capacity. The company was originally known as Nippon Steel Corp but after the merger with Sumitomo Metal in October 1st of 2012, was later changed to “Nippon Steel & Sumitomo Metal Corporation”. In 2012, the company ranked the world second largest steel producer after the union. This report will analyze in deep the company…

3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…

Cast iron cookware is not a thing of the past; it is actually an item that is used by many cooks and homemakers on a daily basis. The cookware that is made of cast iron has many benefits. It conducts heat very well; it heats the food evenly and thoroughly and can even be resistant to foods sticking to it. It is only resistant to foods sticking if it has been seasoned well and not allowed to become unseasoned. If you have never used this type of cookware, you might be pleasantly surprised what…
