Abstract
The utility model relates to a measuring instrument for phase transformation points, which is formed by that a pressure sensor (1), a temperature measuring device (2), a signal processor (3), a pressure and temperature indicator (4) and a permanent magnet (7) are fixed on an outer shell (8). The output ends of the pressure sensor and the temperature measuring device are connected with the input end of the signal processor. The output end of the signal processor is connected with the pressure and temperature indicator. When a phase change happens, the pressure sensor is pressed by the permanent magnet to sent out voltage signals to the signal processor. After the signals are processed by the signal processor, the signals are transmitted to the pressure and temperature indicator to indicate that the phase change happens at the point and display the measured pressure and the measured temperature. The utility model is characterized in that the measuring instrument for phase transformation points has reasonable structure, convenient and accurate measurement for transformation point, etc.
Description
The utility model relates to a kind of transformation temperature analyzer, particularly measures the device of steel ferrite and perlitic transformation point.
When high-speed rod production is carried out controlling cooling after high topic carbon steel rolls, usually be that theoretical foundation is controlled with the CCT curve, the CCT curve of steel is to be formulated under different cooling by the material of a certain particular chemical composition, the foundation of cooling off as control with it has certain limitation, and because the difference of wire rod cooling velocity when the cooling of cooling line, be difficult to determine the relation of blower fan and cooling velocity, so just be difficult to determine accurately phase transition temperature, can not accurately control phase transformation takes place, can not obtain desirable metallographic structure and mechanical property, the steel mechanics performance instability that makes production does not still have the report that is directly used in mensuration transformation temperature instrument at present.
The utility model purpose provides a kind of transformation temperature analyzer, directly measures the transformation temperature of steel, solves the problems referred to above that prior art exists.
The purpose of this utility model is achieved by the following technical solution:
Comprise pressure transducer, temperature measuring equipment, signal processor, pressure and temp display, permanent magnet, shell in the composition of the present utility model, known pressure transducer, temperature measuring equipment, signal processor, pressure and temp display, permanent magnet are fixed on the shell, permanent magnet is placed on the pressure transducer, the output terminal of pressure transducer and temperature measuring equipment is connected with the signal processor input end, and the signal processor output terminal is connected with the pressure and temp display.
Adopt the utility model, when phase transformation takes place, the attraction that permanent magnet is subjected to being detected steel produces pressure downwards, be subjected to the pressure transducer of permanent magnet compressing to send voltage signal to signal processor, the temperature voltage signal that temperature measuring equipment also records to the signal processor transmission, transmission signals is given the pressure and temp display after the signal processor processes, shows that phase transformation occurs in herein, and shows the pressure and temp that records.When tested steel did not undergo phase transition, the pressure transducer pressure reduced, and the numerical value of the pressure and temp that show this moment for not undergoing phase transition can in time conveniently determine transformation temperature like this.
The utlity model has characteristics such as rational in infrastructure, that the mensuration transformation temperature is conveniently accurate.
Accompanying drawing 1 is the utility model example structure synoptic diagram.
Accompanying drawing 2 is the utility model embodiment electrical schematic diagram.
Below with reference to accompanying drawings, further specify the utility model by embodiment.
In an embodiment, comprise pressure transducer (1) in the composition of the present utility model, infrared thermometer (2), signal processor (3), pressure and temp display (4), pilot lamp (5), pressure is set demodulator (6), permanent magnet (7), shell (8), known pressure transducer, infrared thermometer, signal processor, the pressure and temp display, pressure is set demodulator, pilot lamp, permanent magnet is fixed on the shell, permanent magnet is placed on the pressure transducer, the output terminal of pressure transducer and infrared thermometer is connected with the signal processor input end, the signal processor output terminal is connected with the pressure and temp display, pressure is set demodulator and is connected with signal processor, can reconcile the pressure of setting signal processor processing output, pilot lamp is connected with signal processor output, set demodulator setting pilot lamp when phase transformation takes place by pressure and send indicator signal, when phase transformation takes place, the attraction that permanent magnet is subjected to being detected steel produces pressure downwards, be subjected to the pressure transducer of permanent magnet compressing to send voltage signal to signal processor, the temperature voltage signal that infrared thermometer also records to the signal processor transmission, transmission signals is given pressure and temp display and pilot lamp after the signal processor processes, show that phase transformation occurs in herein, and show the pressure and temp that records.When tested steel did not undergo phase transition, pressure transducer pressure alkali was little, the numerical value of the pressure and temp that show this moment for not undergoing phase transition, and pilot lamp extinguishes, and shows not undergo phase transition, and can in time conveniently determine transformation temperature like this.
