Improvement Measures of Air Hole and Shrinkage Defect in Front Axle of Forklift Truck Produced by V-Casting Method
Aiming at the hole defects arising from the development of forklift front axle by V-casting process instead of resin sand process,the air hole and shrinkage defects were greatly reduced and the scrap rate was reduced by controlling melting temperature,pou-ring temperature,carbon equivalent,residual magnesium amount,sand core baking time,as well as adding hot metal pretreatment,chiller and sand core exhaust volume.
