Graphite products with good adsorption. Void structure enables carbon adsorption carbon graphite has good milk price, it is often used as the carbon adsorbent material for adsorbing moisture, odor, and other toxic substances. We did the experiment, a few days before the barbecue hotplate used graphite looks very clean, but put on the cooker heating graphite, oil and hazardous substances will see when the last barbecue absorbed slowly leaking, but do not worry with a clean paper to wipe clean food use. Pure charge subcooling large carbon graphite, graphite precipitation is not conducive to the nucleation of graphite milk float less. 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).
