Background technique
Hot investment casting is otherwise known as precision-investment casting, it is a kind of metal forming process, by obtained by model casting
Each casting be the result to cooperate jointly through working procedures, a variety of materials, many technologies.The general technology of model casting can
It is divided into: the die mould that design is met the size requirements with manufacture；Meet the wax of various physicochemical properties by the manufacture of suitable die mould
Mould；The several layers of refractory material in wax pattern surface repetitive coatings；Make wax material all from fire resisting by high-temperature steam and hot water dewaxing
It is removed in material, forms ghost；Liquid metal is poured in ghost；It is finally cooling, shelling and casting cleaning.Wherein, high temperature
The wax of removal can also be reused in the manufacture of wax-pattern.Due to the accurate size of casting obtained by this way, corner angle
Clearly, surface is smooth, final form close to zero pendant, therefore also known as hot investment casting.
In certain special dimensions, such as many of aerospace industry field ultra-large type integral structure component, have in structure
Many local thickness is larger, it is desirable that mould material shrinking percentage is small, good stability of the dimension, good fluidity, flexural strength are high, hardness
Height, surface is smooth and there is wetability refractory material to be made to be easily adhered to model surface.Most of mould material is being made on the market
It is often had the following problems when standby above-mentioned thick big monolithic devices fine structure part: 1) since the shrinking percentage at wax-pattern thick and solid position larger,
It cannot obtain the model of exact scale；2) surface smoothness of wax-pattern is not high, wetability is bad, leads to refractory material mould obtained
The inside of tool easily forms concave-convex, hollow surface.
