Specific implementation mode：
As depicted in figs. 1 and 2, a kind of probe for detecting fused-salt bath fused electrolyte temperature parameter comprising
Probe body 1 and thermocouple 2 offer horizontally disposed first through hole 3, at the bottom of probe body 1 in the lower part of probe body 1
End middle part offers the second through-hole 4 that setting is connected to first through hole 3, is offered and first in the top middle portion of probe body 1
The centre bore 5 of the connection setting of through-hole 3；Thermocouple 2 is set in centre bore 5, and the bottom end of thermocouple 2 is placed in first through hole 3；
The conical cavity 7 that bottom end is connected to setting with first through hole 3 is offered inside probe body 1, the bottom end of thermocouple 2 is placed in conical cavity
In 7；The center line of first through hole 3 and the central axis of probe body 1 and intersection, center line and the probe of the second through-hole 4 are led
The center line of body 1 is point-blank；Several adjusting blind holes 6 are offered along 5 circumferencial direction of centre bore at 1 top of probe body,
The distance between 7 top of bottom hole and conical cavity of blind hole 6 is adjusted for h1, between 7 bottom of bottom hole and conical cavity for adjusting blind hole 6
Distance is h2, h1：H2=3:1；Adjusting blind hole 6 along the distribution of 5 even circumferential of centre bore can effectively hinder melt heat to pass through
Graphite block body is to conducting inside probe body 1, to slow down the liter of crystalline solid in 1 central area of probe body and first through hole 3
