Hot-Zone Analysis

We sell mono crystal grower and poly crystal grower equipments. The goods are not limited to equipment itself, but also sell the hot zone which is key to crystal quality. In order to gain high quality crystals and high production efficiency of mono crystal grower and poly crystal grower. It is essential to carry out research of hot zone analysis.

Therefore, the hot zone sold which is not only designed under long experience, but fully based on the theoretical value. For example, the pulling speed is directly related to production efficiency of mono crystal grower, but considering the production cost, pulling power consumption is also very important. In the design of hot zone, we not only analyzed overall heat balance through thermal desorption, but also take full account of the power consumption and the pulling speed.

Besides, the same as mono crystal grower, power consumption ,cost reduction ,discharging the impurities and casting good ingots of poly crystal grower have become increasingly important. On designing of hot zone, we not only analyzed overall heat balance through thermal desorption, but also fully considerd silicon melt convection which is related closely to excluding impurities .

In summary, we can get all relevant information of the heat distribution from the thermal desorption process. The thermal distribution, crystal pulling speed, air flow and solution convection etc .are essential for designing hot zone.

In addition, we use the hot zone according to thermal analytical results to carry out the ingot casting trials of mono crystal grower and poly crystal grower, and strive to verify the thermal desorption results, and improve the accuracy of thermal desorption.
