The above-mentioned galvanic action lower class Peritectic Alloy stand-in directional solidification crystallizer that is applicable to, surface working dimensional precision is IT5.
The principle of work of crystallizer of the present invention is as follows:
The directional solidification crystallizer of this experiment use finally will make to melt 9 two ends, region and form a thermograde G
t, the hot junction of melting region 9 provides thermal source by hot junction liquid communication heat transfer block 4, hot junction liquid circulation leather hose 51, cold junction liquid circulation leather hose 52, hot junction liquid circulation oil pump 6, the heating of temperature thermocouple 72, hot junction, hot junction, oil bath heater 71, melting zone, hot junction, melting zone with edible salad oil 8; The cold junction that melts region 9 provides thermal source by cold junction oil bath heater 131, melting zone, cold junction liquid communication heat transfer block 12, melting zone cold junction temperature thermocouple 132, cold junction heating with edible salad oil 14, cold junction liquid circulation oil pump 15.Wherein hot junction liquid communication heat transfer block 4 and cold junction liquid communication heat transfer block 12 inner Jun YouUXing chambeies, to guarantee that heat transfer block is fully heated.
Because the fusing point of this experiment sub-Peritectic Alloy stand-in used is more than 100 ℃, so it is the edible salad oil of 230 ℃ with edible salad oil 14 employing boiling points that edible salad oil 8 and cold junction heating are used in hot junction heating, can make like this heated liquid reach 100 ℃ of above temperature, thereby guarantee that sub-Peritectic Alloy stand-in can melt, and meet the required thermograde G of sub-Peritectic Alloy stand-in directional solidification growth
tand certain superheating temperature.
Directional solidification crystallizer, except guaranteeing certain thermograde, also needs to avoid side direction heat radiation, and the sheet glass 2 of thawing region 9 side direction on the crystallizer of this experiment is by heat conductive silica gel and slide glass adhesion.Due to heat conductive silica gel, at 280 ℃, with interior, there is good thermal conduction, so can fully guarantee in thawing 9 both sides, region identical with melting the interior maintenance in region 9 in a longitudinal direction thermograde, this has very important significance according to the direction growth of thermograde to guaranteeing alloy stand-in.Heat conductive silica gel insulativity is very good on the other hand, has so just avoided the positive pole in hot junction and the negative pole of cold junction not by short circuit.
Because the present invention is owing to adopting hot junction, melting zone red copper heat-conducting plate to be connected by the bonding sheet glass of silica gel with melting zone cold junction red copper heat-conducting plate, therefore not only can guarantee to melt the stopping property in region 9, be conducive to melting a stable thermograde G of region 9 two ends formation
tbut also avoided side direction heat radiation, compare with the crystallizer of mechanical connection manufacture in the past, this crystallizer more can be controlled the thermograde in directional freeze process accurately simultaneously, has solved directional freeze experiment and the Real Time Observation problem of high-melting-point class alloy stand-in under galvanic action.For the directed experiment of physical simulation under galvanic action, provide smoothly a very good research platform.
Use crystallizer of the present invention, at 0.2mAmm
-2galvanic current effect under, AMPD-4.1at%SCN class Peritectic Alloy stand-in are carried out to directional freeze crystallization, the result obtaining is according to time sequence, in the result of 0s, 3s, 6s and 9s respectively as shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7.
