smaller vertical centrifugal casting machine
The liquid metal is poured into the rotation of the casting, under the action of centrifugal force the filling and solidification of casting foundry method. Known as the centrifugal casting machine, centrifugal casting machine. According to the different direction of rotation axis casting, centrifugal casting machine is divided into horizontal and vertical and inclined type 3. Mainly used for casting various tubular cast of horizontal centrifugal casting machine, such as gray cast iron, ductile iron pipe and gas pipe, smallest diameter 75 mm, up to 3000 mm in addition to a large bore copper roller by pouring machine, various carbon steel, alloy steel and the outer and inner layer of different components of the bilayer material steel roller. It is mainly used for non circular casting production of various Ring Castings and smaller vertical centrifugal casting machine.Mold for centrifugal casting, the casting shape, size and production batch is different, the choice of non metal (such as sand and shell or plycast), metal or metal inner enough to mould coating layer or a resin sand. Casting speed is an important parameter in centrifugal casting, both must have the enough centrifugal force to increase the compactness of the casting metal, centrifugal force can not be too large, so as not to impede the metal contraction. Especially for lead bronze, centrifugal force is too large will produce the segregation between inside and outside of the casting. General speed to about 1500 revolutions per minute scores. Making
Making centrifugal casting is characteristic of liquid metal under the action of centrifugal force to the filling and solidification, casting metal good feeding effect, compact structure, good mechanical properties; casting hollow castings without riser, metal utilization rate can be improved greatly. The specific shape of the casting, centrifugal casting is a process of material saving, energy saving, high efficiency, but must pay special attention to take effective safety measures.
Centrifugal casting gifts crafts jewelry mainly vertical centrifuge. Commonly used materials for lead tin alloy and zinc alloy with low temperature, the use of rubber mould + by embryo + repair embryo + polishing + in electroplating and various in color, surface treatment of centrifugal casting, processing into finished products. /Iron-Pipe-Centrifugal-Casting-Machine/21.html
