The centrifugal casting process of the rare earth wear-resistant pipe is the technique and method of pouring the liquid metal into the high-speed rotating casting type, so that the liquid metal can fill the casting type and form the casting under the action of the centrifugal force. The centrifugal force enables the liquid metal to fill the casting and form the free surface of the casting, to obtain the cylindrical inner hole, facilitates the exclusion of gases and inclusions from the liquid metal, affects the crystallization process of the metal, thus improving the mechanical and physical properties of rare earth wear tube castings.
According to the spatial position of the rotating axis of the casting, centrifugal casting manufacturers can be divided into two kinds, one is centrifugal casting, the other is vertical centrifugal casting, casting is to inject liquid metal into the high-speed rotating casting inside, can make centrifugal movement when casting, which can be very good the liquid metal can be filled on the surface of the casting, can also be very good from the inside of the metal doping debris.
In the rotation of the rotating Angle to identify which is horizontal which is vertical, horizontal state or Angle in 4 can be called horizontal, perpendicular to the rotating axis is called vertical, can effectively produce effective casting, this way is very fast and convenient to casting casting, can provide production demand for manufacturers to use.
So if we need to consider when filling liquid metal to pour temperature, when we make centrifugal casting most of the shape of tubular, ring, etc., liquid metal in the flush will encounter less resistance, and centrifugal pressure to strengthen its filling ability, pouring temperature can be lower than gravity 5-10 degrees Celsius. There are still many points to consider in the production process.
