The main equipment of the electrical system of the polysilicon reduction furnace is a high-power voltage regulator. The load carried by the voltage regulator is a pure resistance load composed of polysilicon rods connected in series.Study on Failure Modes of Vacuum Brazed Diamond Wire Saw The function of the voltage regulator is actually to electrically heat the load resistor and keep the surface temperature of the silicon rod constant (generally 1080°C).Vacuum Hardening Furnace It can be seen that the large range of adjustment of the output voltage and current of the voltage regulator caused by the large-scale variation of the resistance of the silicon rod is the design feature of this voltage regulator. H400 PRECISION PERIPHERAL GRINDER According to the nature of the actual work, the pressure regulator is divided into a preheating regulator in which the temperature of the silicon rod is heated from normal temperature to 1000 ° C, and a reduction pressure regulator in which the diameter of the silicon rod increases from Φ8 to the final diameter and keeps the surface temperature of the silicon rod at 1080 °C.
