What are the three raw materials in iron and steel making? What are their functions?
1. The steel factory makes steel from iron ore and coal. Both iron and coal mines are near city A, while the demand for steel is in city B, which is 100 kilometers away. The factory makes 1 ton of steel from 1 ton of coal and 2 tonnes of iron to scale. Shipping 1 ton of goods (either raw materials or final products) incurs a terminal cost of $100 (the fixed cost incurred as long as one needs to...
1. The steel factory makes steel from iron ore and coal. Both iron and coal mines are near city A, while the demand for steel is in city B, which is 100 kilometers away. The factory makes 1 ton of steel from 1 ton of coal and 2 tonnes of iron ore. Shipping is costly and exhibits increasing returns to scale. Shipping 1 ton of goods (either raw materials or final products) incurs a terminal cost of $100 (the fixed...
The reduction of iron (III) oxide to iron during steel making can be summarized by this sequence of reaction: K1 2C(s) + O2(g) <--> 2CO(g) K2 Fe2O3(s) + 3CO(g) <--> 2Fe(l) + 3CO2(g) The net reaction is: K = 2Fe2O3(s) + 6C(s) + 3O2(g) <--> 4Fe(l) + 6CO2(g) Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K1 and K2 .
4. Determine the amount of pig iron, steel scrap, and ferrosilicon to produce a gray iron having the composition (wt. %) 3.2 C, 3.0 Si, using a coreless induction melting furnace (30 points). 0,032C0.03 S Typical losses for C and Si elements in an induction furnace are as follows: Element Si Loss, % The following raw materials are available (composition in wt. %) pig iron: 3.8 C, 0.8 Si steel scrap: 0.8 C, 0.5 Si -20% returns: 3.2 C, 3.0...
There are many departments in an integrated steel mill. Coke making, iron making, steel making, hot rolling, tempering, annealing, just to name a few. At the steel mill where I work, there are corporate procedures, documents, plans etc, and those all speak to direct each mill what procedures, plans, certifications, permits, etc. they must develop, possess and adhere to. Within the mill I work at in Middletown, each department has its own Emergency Action Plan (EAP). For this discussion, I’ll...

5. The Netherlands primarily exports agricultural products, while importing raw materials such as natural gas, metal ores, and grains. Analyze the impact of the following events on the Netherland's terms of trade: a. Farm pollution in China is worsening. b. Egypt is planning to import large quantities of liquefied natural gas. c. Germany has a sustainable development strategy for raw materials and energy productivity d. OPEC's agreement with Russia cut oil production and pushing oil prices higher, e. A rise...
High-carbon steel has 1.70% carbon dissolved in iron. What mass of carbon is present in a high-carbon steel knife blade that has a mass of 114 g? Give your answer to three significant figures. Answer in (g C)
Arlington Steel Company is a producer of raw steel and steel-related products. On January 3, 2022, Arlington enters into a firm commitment to purchase 10,000 tons of iron ore pellets from a supplier to satisfy spring production demands. The purchase is to be at a fixed price of $63 per ton on April 30, 2022. To protect against the risk of changes in the fair value of the commitment contract, Arlington enters into a futures contract to sell 10,000 tons...
Excelsior Corporation (Excelsior) is in the business of making specialty steel. It commonly orders its raw materials from a number of suppliers who are familiar with the Excelsior process of making steel and what their raw materials are used for. On January 3, 2010, Excelsior sent a purchase order to Jones Minerals Inc (Jones) to purchase 50 tons of “amalgamated coke in small sized lots” at $1,000 per ton. Coke is a type of processed coal needed in the manufacture...
