Development Trend of Domestic Resistance Furnace Market

Suzhou Jiuwei Electric Furnace Equipment Co., Ltd. has special opinions on the development trend of domestic resistance furnace market

The heating power is changed by interfering with the heating power on and off by intervening the dry and the rest, so that the temperature of the resistance furnace is changed. Product features: The box body is folded and welded by high-quality steel plates. The outline adopts electrostatic spraying process. The furnace is sintered with high-temperature refractory materials. The furnace and the shell are filled with insulation materials and heated by silicon carbide rods or silicon molybdenum rods. Components, used in conjunction with the controller, can measure, display, and control the temperature to keep the temperature in the furnace constant. The integral time defined in ic1 is fixed as a clock pulse time, and the length of the de-integration time is proportional to the size of the measured voltage. It will make the tablet system not work properly. , The temperature control curve can be set according to the process requirements (each temperature control setting curve is composed of 8 sections at most, so as to control the temperature rise and fall speed according to the process requirements, and effectively prevent the temperature from overshooting, and the temperature difference of the workpiece is controlled to be less than ±0 The pid control system is divided into the following four main links: The keyboard input system is mainly used for the input, modification and other functions of the preset temperature.

The 11-position control, the position control method usually uses the contactor as the heating execution part, it is the connection between the position temperature control instrument and the contactor. It is suitable for resistance furnaces with only constant value control. When the system detects that the furnace temperature is higher than or lower than its upper and lower limit set value, the system immediately sends an alarm signal to the personnel so that the countermeasures can be adopted in real time. Summary This lesson introduces the structural features and uses of common heating furnaces in the heat treatment workshop, familiar with these contents, and laying the foundation for the further study of subsequent courses. a0a: i/o line of port a. Does drinking milk have a protective effect on the stomach? Because milk can form an excellent protective layer on the gastric mucosa, it can relieve the erosion of alcohol and other irritating foods on the gastric mucosa and reduce the occurrence of gastric diseases.

The resistance furnace heats up a feast when the temperature reaches or crosses the upper limit. Relay contact k Broken knife:. The control contactor cuts off the heating power supply, and the furnace temperature drops. This system mainly completes data collection, temperature display, furnace temperature control, fault detection and alarm functions. The intelligent controller is completed by the chip machine and adopts the self-optimizing control algorithm for process control.

 The characteristic of the position control method is that the heating power is large, the temperature fluctuates, and the control accuracy is not high, but because the control method has simple circuits and few equipment saddles. There are no strict requirements in the heating process, so it is still widely used in resistance furnaces with small load changes. Features of max1: 11-bit resolution; channel single-ended or 4-channel differential input, input polarity can be set by software; 3 single-or ± working voltage, working current. Should also consider the stiffness of the spiral to ensure that it does not fall down at the working temperature. After the electrical design is complete, adjust the transmitter so that the temperature change corresponds to. Every time when the value is displayed dynamically, it is judged whether p is high level, if it is high level, it means the keyboard corresponding to the nixie tube is pressed down, and the key value ⅲ is recorded. The heating element is placed on the shelf inside the furnace, the crucible is installed in the center of the furnace body, and the upper part is equipped with two reversible semi-circular furnace covers.
