The invention relates to
production control of a
polycrystalline silicon ingot casting furnace and aims at providing a heating
control system and a method based on a top separated control
polycrystalline silicon ingot casting furnace. A side heater in the
system is connected with a side power supply, a top heater is connected with a top power supply, the side power supply and the top power supplyare connected to a power
distribution control module through conducting wires, in addition, the
heat control system is provided with a central control module, a heating control module, a
crystal growing height calculation module, a
temperature control sensor, a lower
water temperature flow rate sensor, a side
water temperature flow rate sensor, a side heater temperature sensor and a top heater temperature sensor, and the
temperature control sensor, the lower
water temperature flow rate sensor, the side water temperature flow rate sensor, the side heater temperature sensor and the top heater temperature sensor are arranged on the top of a furnace chamber. Compared with the prior art, the
system and the method have the advantages that the
crystal growing speed is accelerated, the
crystal growing time is shortened, the crystal growing speed and the crystal growing height can be precisely calculated, the crystal growing process is precisely controlled, the total power of the heater power is reduced, in addition, the
energy consumption is obviously reduced because the crystal growing time is shortened, the crystal growing interface is more smooth, the crystal grain verticality is better, in addition, the crystal favorably grows, and the crystal quality is improved.
