Cast iron metallurgy for improved machinability

Cast iron metallurgy for improved machinability

Abstract. Many opportunities for machining cost savings are believed to exist for those who understand the metallurgy of cast iron and are willing to develop a business approach to ensure good machinability. User requirements for castings are increasing simultaneously with casting cost reduction pressures. Many productivity improvements and cost reduction opportunities begin with higher value castings.

Cast iron metallurgy Britannica

Cast iron metallurgy Britannica

Cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. It is made by reducing iron ore in a blast furnace. The liquid iron is cast, or poured and hardened, into crude ingots called pigs, and the pigs are subsequently remelted along with scrap and alloying elements in cupola furnaces and recast into

Cast iron for gears Metal and Metallurgy engineering

Cast iron for gears Metal and Metallurgy engineering

With a cast iron or cast steel gear, you really must plan to do final machining on it. An as-cast surface is not acceptable for accuracy and surface finish. If you could get a gear set to run as-cast, your clearances and backlash would have to be set too far open, it would be very noisy, and youd almost certainly have excess power loss due to ...
