The invention discloses a
casting iron pan and a
casting process thereof.The
casting process includes the steps of smashing
pig iron, adding
samarium and
neodymium pure
metal into a
smelting furnace to be smelted at a high temperature, lowering the temperature of molten iron to be 1250-1350 DEG C, casting the molten iron in a sand mold, preparing a
nucleation seed crystal agent, instantly putting in the
nucleation seed crystal agent, conducting stirring to evenly disperse the
nucleation seed crystal agent in molten iron till small micro-crystals appear, cooling the molten iron containing small micro-crystals till the molten iron is solidified, conducting demolding to obtain a rough product, conducting
tempering on the rough product, taking out the product,
grinding a tempered casting iron pan till the surface is smooth and presents
metal luster to obtain the casting iron pan finished product, putting the finished product in a closed
package bag, and storing the casting iron pan in a dry, ventilated and cool place.The casting iron pan is high in strength,
plasticity and durability, the problems that the casting iron pan is long in forming time and not stable in performance are solved, and the additional value of the casting iron pan is improved.
