Schoolcraft Blast Furnace
Pictured Rocks National Lakeshore Schoolcraft National Park Service U.S. Department of the Interior Blast Furnace Schoolcraft furnace With surveyor William Burt’s discovery of iron ore near Teal Lake in Marquette County in 1844, Michigan’s Upper Peninsula suddenly became a hub of activity. The discovery led to construction of a vast mining and manufacturing industry using forges and blast furnaces. When the Civil War ended, many of the South’s furnaces had been destroyed by the war. Westward expansion was occurring across the plains and demand for iron boomed. It was during this era that many of the Upper Peninsula’s furnaces were constructed. There were advantages to smelting iron ore from charcoal fires. Iron produced in this manner was low in carbon content, making it highly fusable, strong, malleable and able to withstand shocks without cracking. The iron made fine wagon rims, horseshoes, and railroad wheels. Before the boom times were over, 29 separate furnaces were located on the Old Munising, ca. 1870 peninsula, though not all operated simultaneously. The business of iron making required more capital than was readily available in the area and financing and management of the operations was often complex. The first group of investors were from Philadelphia. They wished to develop a resort village on Munising Bay’s east shoreline in 1850. Some 87,000 acres of timber were purchased for $.85 an acre. A village was platted on the east shore of Munising Bay, lots were sold, and a dock was built. Henry Mather and Peter White acted as agents for the group of investors who created the Schoolcraft Iron Company in 1866.

5. Sirhowy Ironworks
Great Archaeological Sites in Blaenau Gwent 5. SIRHOWY IRONWORKS There were a number of ironworks in the area now covered by Blaenau Gwent County Borough, which provided all the raw materials they needed – iron ore, limestone and fuel, charcoal at first but later coal to make coke. The Sirhowy ironworks (SO14301010) are the only one where there is still something to see. The works were opened in 1778 with one blast furnace. Although it was originally blown by water power, in 1799 the owners invested in a Boulton and Watt steam engine. This gave them enough power to blow a second furnace, which started production in 1802. In the early years of the 19th century, the pig iron produced at Sirhowy was sent to the Tredegar works a little further down the valley where it was refined, until 1818 when the Sirhowy works were sold and started to send its pig iron to Ebbw Vale. A third furnace was added in 1826 and a fourth in 1839. But by the 1870s iron smelting at Sirhowy was no longer profitable, and the works finally closed in 1882. Like all ironworks in South Wales, the furnaces were built against a steep bank which enabled the ironworkers to load the charge of iron ore, limestone and coke or charcoal fuel more easily at the top of the furnace. All that is now left now are the remains of a bank of blast furnaces with the arches that would originally have linked them to the casting houses in front, and the building that originally housed the waterwheel.

Blast Furnace
RECOMMENDED GUIDELINE FOR IRON & STEEL SECTOR MINISTRY OF STEEL, Doc. No: RG / 04 GOVT. OF INDIA BLAST Rev no.: 00 FURNACE Effective Date: -- 1. OBJECTIVE Blast furnace produces Hot metal (Liquid Iron) using Iron ore, Coke, Sinter, Pellets and fluxes such as Lime-stone, Pyroxenite, Quartzite reacting with oxygen from pre heated air. This entire process of production of hot metal is associated with various safety hazards like hit / entanglement with mobile equipment, burns, fire, slip & fall, exposure to dust, smoke, noise, heat & gas etc. 2. SCOPE This code of safety is applicable to Blast furnace Dept. of an Integrated Steel Plant. 3. PROCESS In the Blast Furnaces (BF) liquid iron (popularly termed as ‘Hot Metal’) is produced by the process of reduction at high temperature from raw materials like iron ore, base mix, sinter, coke, fluxes (limestone / quartzite), etc. &also air blast / O2. In blast furnace the process is also known as “Counter current process” as solid raw material is being charged from the top and hot air is being blown from bottom. During the process the impurities are removed in the form of slag and hot metal is produced. Coal is being injected to reduce consumption of main fuel coke which is a cost reduction measure. Liquid metal and slag are being separated in the area known as cast house. The liquid Hot Metal is transported in Hot Metal Ladles / Torpedoes to the Steel Melting Shops (SMS) for the production of steel by the process of oxidation of the Hot Metal in specially designed Convertors. Sometimes the Hot Metal is poured in the Pig Casting Machine (PCM) to produce Pig Iron.

The Stainless Steel Family
The Stainless Steel Family A short description of the various grades of stainless steel and how they fit into distinct metallurgical families. It has been written primarily from a European perspective and may not fully reflect the practice in other regions. Stainless steel is the term used to describe an extremely versatile family of engineering materials, which are selected primarily for their corrosion and heat resistant properties. All stainless steels contain principally iron and a minimum of 10.5% chromium. At this level, chromium reacts with oxygen and moisture in the environment to form a protective, adherent and coherent, oxide film that envelops the entire surface of the material. This oxide film (known as the passive or boundary layer) is very thin (2-3 namometres). [1nanometre = 10-9 m]. The passive layer on stainless steels exhibits a truly remarkable property: when damaged (e.g. abraded), it self-repairs as chromium in the steel reacts rapidly with oxygen and moisture in the environment to reform the oxide layer. Increasing the chromium content beyond the minimum of 10.5% confers still greater corrosion resistance. Corrosion resistance may be further improved, and a wide range of properties provided, by the addition of 8% or more nickel. The addition of molybdenum further increases corrosion resistance (in particular, resistance to pitting corrosion), while nitrogen increases mechanical strength and enhances resistance to pitting. Categories of Stainless Steels The stainless steel family tree has several branches, which may be differentiated in a variety of ways e.g. in terms of their areas of application, by the alloying elements used in their production, or, perhaps the most accurate way, by the metallurgical phases present in their microscopic structures: .
