Sometimes during the process of Bucket Teeth pouring, we will see the bucket teeth sticking sand. So we should take some measures to prevent the phenomenon of sticking sand.
At first, you must ensure there is nothing problem in the sand compaction. If it has been stuck sand on the bucket teeth, the sand is certainly not tight. You had better test each piece of sand. After the core damaged, you must repair it carefully. Certainly you can not allow the partial loose.
Compared to the iron casting, the casting temperature of steel is more higher. Sometimes the temperature could upon 1560℃. High casting temperature is mainly used to prevent the steel casting cold and shut. However the high temperature has long thermal effects on sand. You ought to pay attention to set the gating system and riser. And avoiding local overheating for the casting.
Decreasing casting temperature, speed and height properly. Although the wall of bucket teeth is not thick, the time of thermal effect has been extended. Large dynamic pressure and static pressure during the casting conditions for the mechanical penetration.
