Three Phase Embeded Electrode Salt-bath Furnace

Place of Origin	China

For heating up the metal parts in melted in the salty fluid or the compound salt fluid, in order to carriy on each kind of heat treatment, for example: Quenching, annealing, tempering, normalizing, nonoxidation heating and cementation and so on. This series electrode salt bath divides into the low temperature, warm and the high temperature three kinds, its operating temperature respectively be 150-550℃, 550-1000℃, 1000- 1350℃.

Structure description:
    DM stype Three phase Embeded Electrode Salt-bath Furnace is of the rectangular structure, the outer covering welds by the angle steel and the steel plate, in puts in gallbladder which the steel plate makes, in the gallbladder is uses sets up the salt bath which the brick and the standard brick compose, in the gallbladder is mainly uses in preventing outside the fused salt permeating heat insulating layer and the salt bath, when salt bath damage is advantageous hangs the repair. Between the electrode salt bath's in gallbladder and the furnace shell builds has the heat preservation brick and the stuff heat preservation powder, the electrode is from the salt bath base side entry, surface contact bath salt, other three surface bury in the refractory brick, the above structure achieves the extension electrode service life. As a result of the electrode to the tank bottom 50 millimeters, may avoid like this as a result of the slag deposit creating two electrode short circuits, outside gallbladder's electrode has the water cooling wrap, the fused salt when flows out outward along the electrode, bumps into the water cooling wrap is the coagulation, like this may avoid leaking the salt. Three phase bury the type electrode salt bath to use the salts to make the heating agent, according to the different operating temperature, may select the different ingredient the salt or the compound salt, the salt before the melting not the electric conduction, therefore the salt bath uses time must use the starting electrode to dissolve, because the electric current dissolves the salt through the electric conduction to have the quantity of heat unceasingly, therefore may maintain the dissolve condition, because of the electrode under the electromagnetic force function, causes the fused salt through the natural convection and the electromagnetism agitation to circulate unceasingly, therefore may rapid and the even heating work piece. The furance side is loaded with the fume hood, connects with the workshop exhaust steam pipe, removes the noxious gas which the electrode salt bath produces. Necessary supplies with the electrode salt bath has the electric furance control cubicle, the control electrode salt bath's temperature, on the control cubicle is loaded with the survey which the instruction temperature uses to control the warm idea, with plunges in the salt bath after the extension wire the thermo-element to connect, may instruct the record and the automatic control temperature.
