Heraeus continuous thermometer

Heraeus continuous thermometer

The continuous temperature measurement system for molten steel isHFCOne of the temperature measuring instrument series products. The temperature measurement principle is to place the temperature measuring tube in the intermediate package and immerse it in steel water to a depth exceeding260mmThe temperature at the bottom of the temperature measuring tube is equal to the temperature of the molten steel. The detector installed at the outlet of the temperature measuring tube receives the radiation energy emitted from the bottom of the temperature measuring tube and converts it into corresponding electrical signals, which are transmitted to the signal processor. The signal processor with a microcontroller as the core processes the input signal of the detector and displays the temperature of the molten steel on the display screen. through485The communication interface transmits the temperature signal to the large screen display and outputs it through the output circuit4—20mAThe standard signal is transmitted to the computer.

2. Technical characteristics and significance

Adopting current technologies in the world, the numbers areZL200420070487.2andZL200520090166.3,The temperature measuring tube consists of an outer tube with an open upper end and a closed lower end, and an inner tube with open ends.

•The temperature measuring tube sensing unit adopts a single-layer structure, with short response time and fast response speed.

•The temperature measuring tube has a simple structure and a low failure rate.

•Temperature measuring tubes with different usage effects depending on the site, steel type, steelmaking process, and intermediate package structure.

•The temperature measuring tube is connected to the detector using a non self-locking connection, making it easy to operate.

•The detector has strong dust prevention function, greatly reducing the maintenance of continuous temperature measurement system, ensuring accurate and stable temperature measurement values.

•Accurately compensate for the drift of detectors and signal processors caused by changes in environmental temperature. High precision and wide temperature measurement range.

•The signal processor function * can meet various output requirements of different sites.

•Continuous real-time display of molten steel temperature, keeping track of the trend of molten steel temperature changes at any time. When the trend of molten steel temperature changes abnormally, effective measures can be taken in advance to prevent accidents from occurring

•Beneficial for protecting pouring and preventing secondary oxidation of molten steel

•There will be no splashing of steel flowers during thermocouple temperature measurement, extending the service life of the intermediate bag cover

•The continuous temperature measurement system for molten steel provides a guarantee for the automatic heating equipment of the intermediate ladle to be put into use

•The continuous temperature measurement system for molten steel is implemented with automatic control of continuous casting machine pulling speed and secondary cooling water distribution, improving the quality of castings and effectively suppressing accidents

•Reduced the labor intensity of workers and increased safety

•Can monitor the baking temperature of the intermediate package, and according to the material and structure of the intermediate package, bake according to the ideal baking curve, which can extend the service life of the intermediate package, reduce production costs, and facilitate smooth pouring
