这个Noble专利是通过使用锆砂粉衬铸型,使铸件外形更接近零件的形状。 离心机设计为六筒和二筒的。用来生产大型的内燃机缸套。 该工艺的特点为能生产范围较宽的各种离心铸件。金属型的锆砂粉层是由一个专门的挂砂槽分布与成型。在挂衬槽口上设有特殊形状的刮片,它可满足各种直径及形状的要求。 其工艺过程大致如下:将锆砂粉从储存系统上部加入到挂衬槽中,然后向型内挂砂 This Noble patent uses a zirconium sand powder liner to bring the shape of the casting closer to the shape of the part. Centrifuge design for the six and two cylinder. Used to produce large-scale internal combustion engine cylinder liner. The process is characterized by the ability to produce a wide range of centrifugal castings. Metal-type zircon sand powder layer is a special hanging sand tank distribution and molding. In the liner with a notch on the special shape of the blade, it can meet a variety of diameter and shape requirements. The process is as follows: the zirconium sand powder from the top of the storage system to join the lining tank, and then to the type of hanging sand
