Teach you how to choose the right high temperature furnace

Time:2020-11-20 10:45
Zhengzhou Nuotai Technology teaches you how to choose a suitable high-temperature furnace, please read on:

1. The high-temperature furnace adopts closed-loop technology for triggering control of thyristor module, suitable high-temperature furnace phase-shifting trigger control method, output voltage, current or power is continuously adjustable, with constant voltage, constant current or constant power characteristics; current loop is internal The voltage loop is an outer loop. When a load is suddenly added or the load current exceeds the current limit value, the output current of the voltage regulator is limited to the rated current range to ensure the normal operation of the output and the voltage regulator; at the same time, the voltage loop is also involved in regulation, The output current of the voltage regulator is limited to the rated current range, and the output current and voltage are kept constant under the premise of sufficient adjustment margin; so as to protect the heating element from the impact of excessive current and voltage, and achieve safety and reliability. Control effect and control accuracy.

2. Three layers of insulation are used, namely: aluminum silicate fiberboard, alumina fiberboard, and alumina (polycrystalline) fiberboard. Not only does it have a good insulation effect, but the energy saving effect is more than 80% of the old electric furnace. In addition, if the furnace is used for a long time without stopping, the shell temperature is less than 45 degrees, and this temperature will definitely not cause burns to the human body.

3. Adopt integrated modular control unit, accurate control accuracy, and designed dual-loop control and dual-loop protection, with overshoot, overshoot, undershoot, segment couple, teach you how to choose phase loss, overpressure, and overcurrent , Over temperature, current feedback, soft start and other protections.
