Introduction: This device is used to measure the thermal expansion rate of the semi-graphite carbon block in the state of molten salt electrolysis. It is composed of a domestic high-precision intelligent instrument or an intelligent temperature control system designed with the latest dual microprocessors imported from Japan, a new type of well-type high-temperature furnace, an automatic recording dilatometer and an electrolysis system. It has a series of advantages such as high-precision (0.2-level) intelligence (multiple thermocouple inputs, PID auto-tuning of more than 30 segments, etc.), small size, long life, and convenient use. This instrument is an ideal supporting instrument for the carbon analysis industry, aluminum electrolysis, graphite materials, etc. Refer to the standard YS/T287-1999 aluminum electrolytic expansion rate test method, Technical Parameters: 1. Temperature control: input voltage 220V; 2. Power rate: 6KW; 3. Temperature control range: room temperature～1200℃ 4. Temperature control thermocouple: S-type temperature measuring thermocouple: S-type; accuracy: 0.1 grade; input: a variety of thermocouples are freely input for selection; 5. Display mode: LED double four-digit display of measured value and set value, 7 jobs; 6. Status light, man-machine dialogue and LCD screen display of various parameters 7. Program curve: curve can be preset, each with 9 segments, each step is 9999 minutes, the program can be used for 99 large cycles Control principle: 6 groups of PID parameters, group of output power limiting and 6 groups of anti-overshoot SF factor, suitable for various loads. PID segment setting, manual correction and platform PID self-tuning. Power-on/power-down protection mode: power-on slow output (1-120 seconds) and set energy-saving servo start. The program point is automatically protected when the power is short-circuited. After power-on, the program can continue to run from the protection point. Program monitoring function: When the program is running, it can switch and display the running state in cycles. Digital lock: After all parameters are set, digital lock protection can be set. Output: solid state relay time proportional output. Displacement measurement: (precision digital displacement meter and automatic recording instrument) . Measuring range 4mm ②. Resolution 1μm or 0.1um for choice Electrolysis power supply: (precision constant current source) ①. Voltage 0～12V ②. Current 0～50A
