Product Description

Precision Steel Parts of mechanical properties than cast iron high, but its cast iron than poor performance. Because of the higher melting point cast steel, molten steel easily oxidized, poor flowability of molten steel, shrinkage, its shrinkage rate is 10 to 14% linear shrinkage of 1.8 to 2.5%. To prevent the castings produced water shortage, cold shuts, shrinkage and shrinkage, cracks and other defects sticky sand, must take iron complex than process measures:
1, due to poor mobility of molten steel, steel castings produced in order to prevent cold shut and poured enough can not be less than the thickness of steel castings 8mm; structural strive gating system is simple, and cross-sectional dimensions than the big iron; dry mold or hot mold; appropriately increasing the pouring temperature, typically 1520 ° ~ 1600 ?, because the casting temperature is high, the superheat of molten steel, long time remain liquid, liquidity can be improved. But the pouring temperature is too high, it will cause coarse grains, thermal cracking, porosity and sticky sand and other defects. It is generally small, thin-walled castings and complex shapes, its pouring temperature of about steel melting temperature + 150 ?; large, thick-walled castings pouring temperature higher than the melting point of about 100 ?.
2, due to the contraction of steel much more than cast iron, cast appear to prevent shrinkage, shrinkage defects, mostly using riser and cold iron and subsidies and other measures in the casting process, in order to achieve solidification. In addition, to prevent steel castings produced shrinkage, shrinkage, porosity and crack defects, should make it uniform thickness, avoid sharp corners and right-angle structure plus sawdust in the mold with sand, add coke type core, and hollow core and oil sands cores or core sand to improve the yield and breathability.
Precision Steel Parts of high melting point and its corresponding pouring temperature is high. High temperature molten steel and mold material interaction, easy to produce sticky sand defects. Therefore, we should adopt a higher refractoriness of synthetic quartz sand mold made and brush from zircon sand quartz powder or powder coating was prepared in the mold surface. To reduce gas sources, improve mobility and strength of the mold molten steel, steel castings used mostly dry or drying type to cast, such as the use of sodium silicate sand hardened CO2.
