Large belt pulley carbon steel casting is by sand casting and widely used in forging and press machine.In the manufacture of belt pulley large steel castings, the physical and mechanical properties of materials has a great influence on the selection of process parameters, pouring riser, the setting of cold iron, the heat treatment technology and the post processing technology of steel castings.
The heat treatment of carbon steel castings shall be normalized or annealed unless indicated in the drawings and relevant technical documents. The mechanical properties and functions after normalizing or annealing shall conform with rule.The mechanical properties of carbon steel castings, in which the shrinkage and impact toughness of cross-sections are tested without special requirements. In the actual production, general carbon steel casting, especially small carbon steel castings, all directions with the same yield, although this will make some errors, but the error is generally not so large and so ,it is more easy for the mold manufacturing.
To master the shrinkage and deformation while the carbon steel castings solidify and cool in the mold is the key technology to ensure the basic outline and dimensional accuracy of carbon steel castings. There are many factors that affect the shrinkage of carbon steel casting. The main are: the yielding of the carbon steel casting, the material of the carbon steel casting and the structure of carbon steel casting.If you are interested in our carbon steel cast belt pulley large sand casting for forging and press machine, please be free to buy the quality products made in China from our factory.
