Today, let's talk about how to choose the right high temperature furnace?
1. High temperature furnace adopts closed-loop technology, thyristor module trigger control, phase-shift trigger control mode, output voltage, current or power can be continuously adjustable, with constant voltage, constant current or constant power characteristics; current loop is inner loop, voltage loop is outer loop, when sudden load or load current exceeds current limit, limit the output current of voltage regulator within the rated current range, to ensure the output and output The voltage regulator works normally; 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 adjustment 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.
2. Three layers of heat preservation are adopted, which are aluminum silicate fiberboard, alumina fiberboard and alumina (polycrystalline) fiberboard. The heat preservation effect is good, and the energy saving effect is more than 80% of the old electric furnace. And the long-term use of the furnace, the shell temperature is less than 45 degrees, this temperature will not burn the human body. The integrated module control unit is adopted, the control precision is accurate, and the double circuit control and double circuit protection are designed, which is suitable for high temperature furnace? With overshoot, overshoot, under regulation, section couple, how to select phase closing and missing, overpressure, over current, over temperature, current feedback, soft start and other protection.
