Iron ore - Wikipedia

White cast iron is more brittle, but also harder. It is generally avoided, because it is difficult to work, except in China where high sulfur cast iron, some as high as 0.57%, made with coal and coke, was used to make bells and chimes (Rostoker, Bronson Dvorak 1984, p. 760).

Is cast iron cookware from China safe? - Seasoned Advice

Cast iron density is around 6800 - 7800 kg/m3. At the higher figure this works out to a volume for my skillet of 2.1/7800 m^3 = 2.7 x 10^-4 m^3= 270cc. Ignoring the handle and sides, let us consider only the flat cooking surface diameter 20cm, and assume a depth of say 1mm available to leach the lead. Volume of a cylinder = pi r^2 x h = 3.14 x 10cm^2 x 0.1 = 31.4cc. Thus 31.4/270 x 100 ...

Cast Grinding Steel Balls - 911Metallurgist

In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive. Meulendyke, Moroz, and Smith (1987) reported that it is in the low abrasive environments where the corrosive component of wear can become quite significant. In ...

Ferrous metallurgy - Wikipedia

One of the fragments was made of bloomery iron rather than meteoritic iron. The earliest iron artifacts made from bloomeries in China date to end of the 9th century BC. Cast iron was used in ancient China for warfare, agriculture and architecture. Around 500 BC, metalworkers in the southern state of Wu achieved a temperature of 1130 °C. At this temperature, iron combines with 4.3% carbon and melts.
