Heating measurement is one of the main process parameters of thermal solution process and precision casting process.Freezing is also the indispensable method in the process of thermal solution. In the process of precision casting, the freezing method will not be the same as that of thermal solution due to the inconsistency between precision casting and thermal solution. The secondary task is to master the freezing progress.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.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.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 follows the nonmetallic data being solved and the thermal solution.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.Choosing and mastering heating measurement is the main achievement of ensuring the quality of heat solution.

 The information mentioned by it indicates a method for the preparation of quartz casting powder for precision casting. It is composed of quartz powder, low-temperature quartz powder mixture and liquid binder, and can also add low-temperature stabilizer, defoaming agent and coagulant according to the application situation. This news underground a method for the preparation of quartz powder for precision casting, it is made up of quartz powder and low-temperature quartz powder mixture, liquid binder mixture, but also according to the status of the application of low temperature stabilizer, defoaming agent, coagulant. Precision casting with Shi Yingzhu powder to meet the needs of its profit is low, using the bento, practical scope is wide, the type of shell deposit are excellent strength and excellent printing machine, no crack, no deformation, no adhering sand, fled and casting in casting in the name of lubrication, high measure precision, casting decent rate is very high.
