Hexin precision casting on the casting temperature control is very good, because only to master the temperature of the castings produced castings to achieve the desired effect so as to not be so many defective products, and effectively improve the quality of the casting, if you want to know the secret, just follow me to see the tips below together!1, improve the precision casting temperature, often can make the liquid core length increases, produce the organization of the columnar crystal orientation increases, the crack scrap increases, and increases the ingot surface segregation to the degree of content.In fact, each precision casting temperature 30 ℃, the average temperature of the liquid cavity only 1 ~ 2 ℃.Liquid core melt temperature, although only improve within 2 ℃, but the defects of ingot casting and its influence is very big.In the production of 10 mm diameter aluminum rod, due to the casting speed, when the casting temperature is too high, on the surface of aluminum rod prone to heavy leather phenomenon, is designed, even without the leakage liquid aluminum solidification.
