Electrode salt bath furnace
Â
According to submerged electrode salt bath furnace heating furnace electrode into different parts, is divided into "side of the buried electrode salt bath furnace" and two kinds of "top buried electrode salt bath furnace." Buried side electrode salt bath furnace electrode into the furnace from the furnace due to the side, and therefore require particular attention in the manufacture of electrodes inserted into the parts of the seal! Contrast "Top buried" electrode salt bath furnace, buried side has the upper mouth convenient loading and unloading the advantages and disadvantages that is likely to cause the side Mifengbuyan dense, drain the salt!

Embedded electrode salt bath furnace is the national standard of energy-efficient furnace operation cycle for heating the molten salt solution or a salt solution mixed metal parts, for hardening, annealing, tempering, normalizing, no oxidation and heating carburizing heat treatment. Bath heaters are divided into low, medium temperature and high temperature three categories, namely its working temperature 150 ~ 650 ℃ 650 ~ 950 ℃ 950 ~ 1300 ℃.

DM-se electrode salt bath furnace system embedded rectangular structure, housing made of angle iron and steel plate welded into the inner release e of steel, the interior is the use of established standards brick and tile composition supplemented ramming real puzzle salt bath, the mainly used to prevent the infiltration of molten salt thermal insulation and outside the tank, when the salt bath for easy hanging out damage repair. Puzzle between the the furnace shell and filled with insulation powder insulation bricks, electrodes are buried in the bottom of the salt bath, bath salts a surface the remaining three face buried in refractory bricks, each block has a copper electrode connected to copper from Salt tank top stuck, and the transformer is connected to form a loop. This structure is completely solved the leakage problem, due to the electrode from the bottom mm, it can avoid the slag deposition due to a short circuit caused by the two electrodes. Largely extend the life of the furnace body and the electrodes.

Embedded electrode using salt bath heaters as a heat transfer medium, depending on the operating temperature, the choice of salt or a mixture of different ingredients, salts before melting is not conductive, so you must use when starting electrode dissolves salt furnaces , since the current through the conductive salt dissolved continually generate heat, it can keep the solubilized state, due to the electrodes under the action of the electromagnetic force, through natural convection and electromagnetic stirring constantly leaving the molten salt circulation, it can be quickly and uniformly heat the workpiece. Side of the furnace is equipped with an exhaust device connected to the plant's exhaust pipe, remove harmful gases produced by salt bath furnace. There are electric control cabinet with salt furnace matching supply to control the salt furnace temperature control cabinet is equipped with a measuring temperature indicates the temperature gauge, the compensation sed in a salt bath thermocouple connected to indicate recording and automatic adjust the temperature.
