Graphite flake graphite flake graphite crystal scaly; it is under pressure metamorphism made of high-strength graphite milk, large scales and fine scales of the points. Features such graphite grade ore is not high, usually in 2 to 3 percent, or between 10 to 25%. Is the nature of one of the best Flotability carbon graphite ore, after more grinding multiple choice available high grade graphite concentrate. Such graphite floatability, lubricity, plasticity than other types of graphite superior; therefore it is the largest industrial value. Pure charge subcooling large, is not conducive to the nucleation of graphite precipitation, less float. The main measures should be controlled to prevent the carbon equivalent according to the casting wall thickness; when small pieces of the wall thickness of not more than 30mm, appear critical carbon graphite floating equivalent of 4.7% - 4.9%; when the wall thickness of 30 to 100mm, appear critical carbon graphite floating equivalent of 4.5% - 4.6%; float appeared critical graphite carbon equivalent of 4.4% ~ 4.5% when the large wall thickness greater than 100mm. In particular, to control the carbon is less than 4. O%; the appropriate use of scrap, pig iron and silicon lower back with the use of charge; controlling the residual amount of rare earth is not too high; pouring temperature control; large cross section castings may be appropriate to add molybdenum or partial placement also prevents cold iron graphite float (see carbon equivalent cast iron, ductile iron).
