As shown in fig. 1-3, a temperature measuring device of an electromagnetic induction heating device comprises an indirect sampling coil 2 connected with a heating coil 1 of the electromagnetic induction heating device in parallel, wherein an indirect sampling crucible 3 is arranged in the indirect sampling coil 2, a plurality of sampling tubes 4 are arranged in the indirect sampling crucible 3, mounting grooves 41 are formed at the top ends of the sampling tubes 4, and temperature measuring elements are arranged in the mounting grooves 41.
The temperature measuring element is a thermocouple.
The top surface of the indirect sampling crucible 3 forms a convex edge 31.
The outer diameter of the raised edge 31 is larger than the maximum outer diameter of the indirect sampling coil 2.
A plurality of through holes 32 are uniformly distributed on the convex edge 31.
Example 2
The temperature was measured for further convenience based on example 1.
The heights of a plurality of sampling pipes 4 are different, so that the sampling pipes are suitable for temperature monitoring when crucibles with different sizes are placed into the heating coil 1.
The sampling pipes 4 are different in height, after the thermocouples are placed in the sampling pipes, the distances between the thermocouples and the indirect sampling coils 2 are different, and the distances between crucibles and the heating coils 1 when the crucibles of different sizes are placed in the heating coils 1 are well simulated.
The height values of a plurality of the sampling tubes 4 form an arithmetic progression.
The heights of a plurality of sampling pipes 4 adjacent to the inner wall of the indirect sampling crucible 3 are increased in sequence in an arithmetic progression clockwise or anticlockwise.
When a plurality of sampling pipes 4 are arranged in a quincuncial array mode, the height of the sampling pipe 4 positioned at the central position is the highest, and the heights of the peripheral sampling pipes 4 are increased in an arithmetic progression manner clockwise or anticlockwise.
In the embodiment, seven sampling pipes 4 are arranged to form a quincunx shape, and the middle sampling pipe 4 has the highest height.
The top surface of the sampling tube 4 with the highest height is lower than the top surface of the indirect sampling crucible 3.
The outer circumferential walls of the adjacent sampling pipes 4 are arranged tangentially.
The use method of the invention comprises the following steps:
when the sampling device is used, target metal is put into a crucible in the heating coil 1 for heating and smelting, the smelting process is started, firstly, which crucible is used is determined (the position of the sampling tube 4 is determined according to the size of the crucible), a thermocouple is put into the corresponding mounting groove 41 of the sampling tube 4 in the indirect sampling crucible 3, the electromagnetic induction heating device is started, and at the moment, the temperature change acquired in the indirect sampling crucible 3 is basically the temperature change of the heating area of the crucible for zone smelting. When moving heating is carried out, the new heating area can be heated up quickly due to the special characteristic of electromagnetic induction heating. Meanwhile, due to the adoption of the parallel connection mode, the load changes, and the temperature in the indirect sampling crucible 3 also changes correspondingly.
