Casting Process of Bucket Adapter

Forging casting: forging the bucket tooth generally adopt alloy steel, forging machinery for special metal blank pressure, extrusion under high temperature, refining crystal material of forgings, make its produce plastic deformation in order to obtain certain mechanical properties, metal after forging processing can improve the organizational structure, can guarantee the forging bucket tooth has a good mechanical performance, more wear-resisting, long service life. The casting is to melt the metal at high temperature, add auxiliary materials, inject the model, and obtain the casting after solidification. The casting produced by this process is easy to produce pores and form traches, and its mechanical properties, wear resistance and service life are lower than forgings.

Precision casting:

With fusible materials meltability model, on which the coated with several layers of tailor-made refractory coating, after drying and hardening type to form a whole shell, reoccupy steam or hot water from the melt in the shell model, and then put type shells in the sand, dry sand by filling in all round its modelling, finally will be cast into the furnace after high temperature roasting, cast type or shell after roasting. A casting is obtained by pouring molten metal into it. The products obtained are precise and complex, close to the final shape of the parts, and can be directly used without processing or rarely processing. It is an advanced process of nearly net shape formation, and an excellent process technology in the casting industry. Its application is very wide. It is not only suitable for casting of various types and all kinds of alloy, but also produces castings with higher dimensional accuracy and surface quality than other casting methods. Even the castings which are difficult to be cast by other casting methods are complicated, high temperature resistant and not easy to process.
