Why we need to adjust the iron liquid of Corten A weathering steel plate steel plate

If the pouring temperature is too low, and the iron liquid in the mold cavity does not have enough heat to cause impurities, slag and so on in the molten iron. The garbage and gas can not rise to the top in time to discharge. Then the formation of inclusions, slag, gas inclusions and other defects will happen to Corten A weathering steel plate.

Although the heat capacity of different kinds of dry sand is different, the cooling rate of the mold is slower than that of sand mold casting, and the whitening tendency of gray cast iron is smaller; for nodular cast iron, the surface of the castings is lower than that of metal mold or sand-coated metal mold when the rigidity of dry sand mold is lower than that of metal mold casting. The casting shell formed by the injection is wear-resistant, so we must adjust the iron liquid of Corten A weathering steel plate or take corresponding measures.
