Due to the different process conditions, we produce low-temperature casting wax of the same grade of low-temperature casting wax in composition, structure, crystallization state is also very different, casting wax mold from which we can see that nickel-based superalloy production of steam turbine blades require smooth surface, clear edges, accurate size, excellent quality, low-temperature casting wax Al carbon number distribution is much wider than A2 and A3, and the distribution is more uniform, indicating that low-temperature casting wax Al than A2 and A3 thermal shrinkage and expansion is smaller and much more stable, In addition to the type of binder and mold and the rheological properties of the coating, these are also closely related to the preparation process of the mold shell. It is more suitable as the base material for a series of precision casting waxes. Taking into account various factors, it is believed that the low-temperature casting wax of grade A is relatively suitable for use as the base material of low-temperature precision casting wax.
