Connection.
The sample Quick connection part is buckle or hook.
Metal material sample to be detected, is put into the salt bath for having installed salt bath by the method for detecting metal material phase transition temperature
In stove, metal material sample is connected on a steel cord by sample Quick connection part, counterweight is placed into balancing disk, makes steel wire
Rope both ends reach balance, and adjust the position of laser level receiver, laser level receiver is reached phase with laser emitter
To horizontal level；Salt bath furnace to be opened to be heated, heating-up temperature is undergone phase transition after reaching the phase point temperature of metal material sample,
The volume of the metal material sample undergone phase transition can produce significant changes, so that cause its buoyancy in salt bath to change,
Break the balance at steel wire rope both ends, so that steel wire rope is moved along fixed pulley, the upper bottom of the laser emitter on steel wire rope
Put and also change correspondingly, while also change the laser signal received of laser level receiver, work computer records laser
Thermocouple is transferred to the temperature data in work computer when the laser signal of horizontal receiver changes, and the data are as to be measured
The transformation temperature of sample.
Beneficial effect
Compared with prior art, special processing is not required using the sample used in the present invention, since the volume of its measurement becomes
Change is three-dimensional, avoids the measurement difference that the anisotropy of the lattice of crystalline material is brought.The change record of data is automatic
Realize, it is not high to the skill set requirements of testing crew.And the global design of the device can preferably reduce environmental factor and cause
Error, since special clamping is not required in sample, measuring speed is fast.It is also suitable for measurement and the inspection unit of factory mass production
Measure batch.It is particularly suitable for the work of a large amount of phase transformation point datas of the requirements such as drawing diagram.
