What is Realistic Fiction. Materials: Several fiction titles from realistic and fantasy genre. Vocabulary: Fiction, realistic, fantasy. Motivation: Engage studentsâ attention by asking the following questions:
Heat number. An example of a heat number on a plate. A heat number is an identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill. Industry quality standards require materials to be tested at the manufacturer and the results of these tests be submitted through a report, also called a Mill Sheet, Mill Certificate or Mill Test Certificate (MTC).
To calculate the wattage requirement to heat steel, use the following equation: Watts = 0.05 x Lbs of Steel x Î´T (in Â°F) / Heat-Up Time (in hrs) Example: To heat 50 lbs of steel by 250Â°F in 1 hour; .05 x 50 x 250 / 1 = 625 Watts. Using the same example, reaching temperature in 15 minutes (0.25 hrs); .05 x 50 x 250 / .25 = 2,500 Watts. This equation is suitable for mild and stainless steels.
