The important role of Silicon in cast

In cast iron, Silicon is an alloy of graphite into the strongest element, its ability to promote graphite, copper-nickel 3 times, 5 times. And in either liquid or solid cast iron, silicon and iron-binding is stronger than carbon.

Containing Silicon in liquid iron, would decrease the solubility of carbon. Higher content of Silicon in molten iron, corresponding to the lower carbon content, more carbon will be squeezed out.

We from iron carbon phase figure in the not difficult understanding: iron liquid for had total crystal components Shi, Silicon content high, solidification process in the, on has more of carbon to primary graphite of form precipitation, until remaining of iron liquid reached total crystal components Hou occurred total Crystal change; iron liquid for Asia total crystal components Shi, solidification process in the, Silicon rich set Yu primary Austrian's body in the. Total Crystal change Shi, Silicon rich set Yu early crystal of total Crystal Austrian's body in the, inhibit carbon and iron of synthesis carburizing body, enhanced carbon in Austrian's body in the of diffusion speed, prompted carbon to total Crystal graphite of form precipitation; total analysis change Shi, solid dissolved Yu Austrian's body in the of silicon, still inhibit carbon and iron formed carburizing body, enhanced carbon in Austrian's body in the of diffusion speed, prompted carbon to total analysis graphite of form precipitation.
