The resistance furnace has significant advantages and a wide range of applications

Box-type resistance furnace product characteristics: The furnace door technology is fully suitable for the principle of the national "gb/z18-2002" thermal processing energy saving technology... to achieve the purpose of energy saving and emission reduction. Therefore, the premise for the transaction of "the robot starts to move the workpiece" is that both pl and p must have tokens. Its benefits are large resistivity, low temperature coefficient of resistance, low bulk density, high use temperature, good heat resistance, constant power, good heat resistance, oxidation resistance, sulfur corrosion resistance, low price, and universal application. The uf capacitor is connected to the power supply for decoupling and selection. p. 3 Design of the main control electricity The main control module electricity is made up of amea single-chip microcomputer and crystal oscillator, reset electricity, isp and jtag expansion electricity. Short-circuit the thermocouple and turn the center screw at the lower end of the temperature indicator to adjust the zero reference point. 1. The furnace door frame is made of cast iron castings, and the crack-free frame is smoothly filled with lightweight or ultra-light refractory materials with good heat preservation.

Combining the temperature and resistance transition characteristics of different types of loads in the resistance furnace, classify and analyze the selection of the trigger mode of the power conversion assembly, and give the suitable trigger control methods for the different types of loads. 8. The two placement methods require that the center of gravity is not deviated, and there is a movable fixed assembly support. , Heat treatment furnace Ji Zesheng, Zhang Xuelong, Wu Yunqi edited, Harbin Engineering University Press. The solid state relay is used as the primary temperature control system in this system. It has the characteristics of long life, high reliability, high flexibility, and low control power. (High-requirement systems add an AC voltage stabilizer. Each of the large and small gears of the converter. The intelligent control and the PID control are connected to realize the intelligent control of the temperature. When the position of the equipment changes, it needs to be re-verified. Improve. The operation rate of the famous electric energy has been increased by 5%, and the de novo distribution of energy-saving heating elements has come to an end.

The focus component of the loop power distribution, following the power electronics technology and digitally controlled thyristor gate and negative input input a positive trigger voltage, the growth of crystalline technology, now most of the use of integrated thyristor power control thyristor conduction, A positive voltage is applied between the anode a and the cathode k, and there is a device to realize the reasonable distribution of the load power of the resistance furnace.

The basics of work affair, basic composition, technical indicators, etc., the key power regulator mainly focuses on the non-contact switching feature of the thyristor, which enables the device to compete against the advantages and errors of the two primary triggering methods of thyristor rectification, and block or The blocking condition is converted to the on or on condition, and the voltage waveform on the load is adjusted by changing the condition of the trigger power adjustment mode and the duration of the on-time change through the device breaking and connecting the resistance furnace load condition. After a few milliseconds, the chip machine enters the working condition. Therefore, the temperature control of the single-chip microcomputer is a control problem that is often encountered in industrial production. The affair of the fixed-value switch control system is that if the measured temperature is lower than the set temperature, the control switch is turned on for heating, and vice versa, the control switch is turned off. The 7533 dam safety monitoring project supervision implementation rules are wrong and undecided bookmark. The control power of the thyristor regulator is necessarily limited, which is mainly affected by two aspects. The first is the limitation of the thyristor's own rated work, which cannot be increased without limit; it is an extremely large operating voltage, and the temperature of the thyristor rises due to fever. ; Cooling or air cooling is not enough to meet the requirements. It is necessary to adopt compulsory water Ling, which adds to the complexity of the equipment. The application site has also been restricted. The ventilation holes at the back of the machine must be clean for ventilation and drainage. Resistance furnace manufacturers
