HENRY FORD TRADE SCHOOL. PART 2. [METALLURGY] Produced: 1927

Description The original catalog description provided by the Ford Motor Company reads as follows: “Chemistry laboratory -- beginners learning to identify metals.” Boys working in chemistry laboratory. “Advanced students determining the percentage composition of steels and non-ferrous alloys for school foundry.” Boys in chemistry laboratory, instructor moving among them. “Pouring a test bar of cast iron for analysis in the school laboratory.” Hands holding small ladle with tongs pouring molten metal into mold - tongs removing hot bar from mold. “Drilling samples of cast iron from school foundry for testing percentage of carbon content. These drillings are accurately weighed.” Boy drilling metal bar, placing drillings on piece of paper, weighing them, brushing them into small tray, pouring something over them, placing tray into tubular oven. “When heated in the presence of oxygen, carbon leaves the cast iron, forming carbon dioxide (CO2). This is collected, weighed, and the carbon content computed.” Removing tray from oven. “Weighing.” Using microbalance. “Metallography -- studying the theory of steel heat treatment.” Classroom, teacher in front of blackboard lecturing to students. “Studying structural changes taking place during the heating and cooling of a metal.” Boys working with laboratory equipment. “Testing hardness of steel sample.” Using testing equipment. “Polishing steel samples for examination under the microscope.” Boys in classroom polishing steel by hand. “Sample must have mirror like surface.” Boy etching steel. “Etching with acid to bring out the structure of the metal.” Instructor and student in laboratory - close-up of piece of metal. “High magnification shows the effect of hammering and heat treatment. The student feels himself a discoverer viewing a new world.” Boys examining metal through microscope - views of metal through microscope. “To avoid vibration while photographing the sample under high magnification the microscope is mounted on cushion of air.” Students using apparatus - student discussing photograph of magnified metal. “Time for hot lunch and good fellowship.” Boys setting tables in dining room - boys eating - boys clearing and dishes. “Class work is supplemented by supervised observation and study of actual work in the Ford Industry.” Group of boys in plant yard. “Coke used in the reduction of iron ore.” Group watching discharging coke oven. “A class in metallurgy at the blast furnace.” Group watching molten metal flowing from furnace through ditch into ladle cars. “Ford Trade School boys need no Aladdin’s lamp.” Group watching huge tongs of overhead crane removing ingot from soaking pit, dropping it into conveyor. “White hot ingots go hurtling to the rolls where they are squeezed to blooms of standard size.” Ingot on conveyor into bloom mill. “Back and forth through smaller rolls the glowing blooms writhe and struggle into standard stock.” Group watching. “Working a steel ingot.” Boys watching crane removing ingot from furnace - ingot being shaped in press. “Part Three will follow immediately.” [1927]
