How does the vertical tube furnace temperature control system work?

How does the vertical tube furnace temperature control system work? Let’s take a look.

The temperature control system is a component with scientific and technological content in the vertical tube furnace components. It is the first automatic control system. Its application on the vertical tube furnace has the same significance as a milestone. It improves the manual control of the traditional electric furnace. This situation not only greatly improves the work efficiency of vertical tube furnaces, but also makes temperature control more accurate. The application of program temperature control systems promotes the modern technological process of vertical tube furnaces, and also reflects the intellectualization of my country’s industry. The level of development is gradually improving

One step: vertical tube furnace temperature measurement and control

The thermocouple collects the signal through the temperature control instrument, and measures and controls the trigger board to control the conduction angle of the thyristor, thereby controlling the current of the main loop heating element, and keeping the vertical tube furnace at the set working temperature.

Two Steps: Selection of Materials in the Furnace of Vertical Tube Furnace

The furnace body material of the vertical tube furnace shall be made of refractory materials such as alumina, refractory fiber and lightweight bricks, and electric heating elements such as silicon molybdenum rods and silicon carbide rods shall be used to provide the heat source. The controller shall be a thyristor temperature controller, * **Improve the real-time performance and control accuracy of vertical tube furnace temperature control.

Three steps: multiple vertical tube furnaces can be controlled by a computer system

After the computer temperature control system is widely used on vertical tube furnaces, one computer can control multiple vertical tube furnaces at the same time, realizing automatic program control. It also has functions such as multi-point temperature display, record storage and alarm.

Four steps: vertical tube furnace thyristor control

Vertical tube furnace thyristor temperature controller is composed of main circuit and control circuit. The main circuit of the vertical tube furnace is composed of thyristor, overcurrent protection fast fuse, overvoltage protection tube electric furnace heating element and other parts. The control loop of the vertical tube furnace is composed of a DC signal power supply, a DC working power supply, a current feedback link, a synchronization signal link, a trigger pulse generator, a temperature detector and a temperature control instrument of the tube electric furnace.
