Ice is also a hot solution precision casting process method, no short in the process of going freezing method in precision casting enterprise will because of smelting process and thermal solution process with no with and without secondary to freeze at their own pace, ice normal annealing schedule is the slowest, is fast freezing schedule compare. The quenching freezes faster progress. Choosing and mastering heating measurement is the main achievement of ensuring the quality of heat solution.

Simply because there is no steel with the same type and without the same request, similar air hardened steel can be used to normalize the same freezing process to stop hardening. Heating measurement is one of the main process parameters of thermal solution process, and also one of the main process parameters in fine smelting process. When adopting high energy density heating and nominal heat solution, the heating progress is very fast, there is no fresh time normally, and chemical heat solution fresh time is generally compared to long. The heating measurement is not the same as the non-metallic data to be solved and the thermal solution, but the normal is to be heated to the phase measurement above the loss of low temperature mechanism. In addition to changing the required amount of time, so that when the nominal non-metallic parts reach the required heating measurement, the demand is also this measure to maintain the required amount of time, make the inside and outside measurement, change the microstructure completely, this period of time is called fresh time.

   Precision casting based on final goods and suppress the paraffin wax class information into accurate light wax models, is coated on the wax pattern multi-layer refractory materials, soften dry paste after a shell, and then the wax models within the condensation is shell setting out, then shell roasting make it strong, boring, originally and then condensation of non-metallic liquid poured into the shell, non-metallic type is shell liquid accurate after freezing and condensation changes in light of the casting. Compared with the sand smelting method. This precision casting process can consume fine and simple, close to the initial shape of the goods, but no processing or very little processing can be used indirectly non-metallic components or delicate works of art, because it is a near net shape of non-metallic liquid forming process.
