How to determine the safety and reliability of high temperature furnace

High temperature furnace is a kind of electric furnace with high temperature, which can reach 1800 ℃ at most. Some customers will ask if the furnace with such high temperature will be burned when it is operated accidentally? Because it is hard to avoid touching during operation. High temperature furnace manufacturers tell you: will not be scalded. Take our products of Shanghai gui'er Machinery Equipment Co., Ltd. as an example, our high-temperature furnace has the following three safety aspects:

1. Three layers of heat preservation are adopted, which are aluminum silicate fiberboard, alumina fiberboard and alumina (polycrystalline) fiberboard. Not only the heat preservation effect is good, but also the energy saving effect is more than 80% of the old electric furnace. And long-term use does not stop the furnace, the shell temperature is less than 45 degrees, this temperature will not cause burns to the human body.

2. Using the closed-loop technology SCR module trigger control, phase-shift trigger control mode, the output voltage, current or power can be continuously adjustable, with the characteristics of constant voltage, constant current or constant power;

The current ring is the inner ring and the voltage ring is the outer ring. When the load is suddenly applied or the load current exceeds the current limit, the output current of the voltage regulator is limited within the rated current range to ensure the normal operation of the output and voltage regulator;

At the same time, the voltage loop also participates in the regulation, so that the output current of the voltage regulator is limited within the rated current range, and the output current and voltage are kept constant under the premise of sufficient regulation margin;

So as to protect the heating element from the impact of excessive current and voltage, and achieve safe and reliable control effect and control accuracy.

3. The integrated modular control unit is adopted, the control accuracy is accurate, and the double loop control and double loop protection are designed, with the protection of overshoot, overshoot, undershoot, section couple, lack of phase, overpressure, overcurrent, overtemperature, current feedback, soft start, etc.

Through the above three protective measures, it can ensure that the staff will not be scalded or other accidents when operating the high-temperature furnace.
