Casting description:

The axle alloy steel sand casting can bear the load,impact and vibration due to steel castings are high strength and good toughness. The variety of steel casting material from ordinary carbon steel, low alloy steel to high alloy steel.Due to the forming by casting method, the size, quality and structure complexity are unrestricted.

 

Steel casting is easy to be cracked into hot tearing and cold cracking.hot tearing is fracture oxidation, dark and curved shape.cold cracking fracture is neat, clean and silver-white.The condition of hot tearing is first the metal has a larger line contraction and is hindered.Second,the low melting point segregation exits in the liquid metal.Third, liquid metal flowability is poor. After the casting is completely solidified, the crack is called cold cracking when the elastic transition temperature is lower than 600-700 . The reason for cold cracking is the internal stress (thermal stress and shrinkage stress,etc) is higher than the strength of steel at this time.The influence factors of cold cracking is first the chemical composition,not easy to be cold cracking, high carbon steel plasticity is poor that is easy to be cold cracking; Second, the smelting process, the degree of deoxidation, if there are more inclusions,it will reduce the plasticity and strength of steel and result in cold cracking.steel casting structure and each casting’s wall thickness are different,and also there are different shrinkage time, so it is easy to make steel casting cracked;open box time and cool slow in the sand box,cool fast in the air and large internal stress.

 

Casting advantage:

1. Steel casting is weldability.It is not only good for the repairing of casting defects, but also adopt the casting weld structure method to meet the requirements of some special casting.

2. Cast steel casting is higher strength,toughness and good weldability.
