Description
Technical field
The present invention relates to a kind of salt bath furnace, particularly relate to a kind of salt bath furnace with submerged electrodes.
Background technology
Salt bath furnace be with melting saline solution as heating medium, workpiece is immersed the industrial furnace heated in saline solution.In the use procedure of salt bath furnace, the use of homogeneity on salt bath furnace of the temperature in the heat-up rate of salt bath furnace and stove causes very large impact.The heat-up rate of salt bath furnace then reduces the effective rate of utilization of resource and increases production cost, the raising of unfavorable productivity effect too slowly.The homogeneity of the temperature in the stove of salt bath furnace is undesirable, can affect the quality of production of processing work, and unfavorable production.The problems referred to above are the problems that should be solved in the use procedure of salt bath furnace.
Summary of the invention
The heat-up rate that the object of this invention is to provide a kind of salt bath furnace with submerged electrodes solution salt bath furnace then reduces the effective rate of utilization of resource and increases production cost, the raising of unfavorable productivity effect too slowly.The homogeneity of the temperature in the stove of salt bath furnace is undesirable, can affect the quality of production of processing work, and the problem of unfavorable production.
Technical solution of the present invention is:
A kind of salt bath furnace with submerged electrodes, comprise electrode, metal flue, thermofin, furnace shell and bell, the salt bath that standard square is built into is provided with in described metal flue, heating medium is provided with in described salt bath, described metal flue, thermofin and furnace shell set gradually from inside to outside, described thermofin is built into by insulating brick, and insulating powder is all filled by the gap place between insulating brick, the end of described electrode is successively through described furnace shell, thermofin, metal flue, and be placed in described salt bath, between described electrode and furnace shell, watercooling jacket is equipped with between electrode and thermofin, the bottom land of described electrode and described salt bath forms the interval of 55-70mm, described bell is provided with extraction hood.
Further improvement is: described furnace shell is that angle steel and Plate Welding form.
Further improvement is: described salt bath furnace with submerged electrodes is also provided with temperature alarming device.
Further improvement is: described heating medium is sodium chloride solution, Klorvess Liquid, barium chloride solution, sodium cyanide solution, potassium cyanide solution, sodium nitrate solution or potassium nitrate solution.
A kind of salt bath furnace with submerged electrodes of the present invention, rate of heating is fast, and in-furnace temperature is even, and workpiece is in heating in heating medium all the time, and when workpiece is come out of the stove, surface is again with one deck salt film, so workpiece surface can be prevented to be oxidized and decarburization.According to the working temperature of stove, sodium chloride solution, Klorvess Liquid, barium chloride solution, sodium cyanide solution, potassium cyanide solution, sodium nitrate solution or potassium nitrate solution can be selected as heating medium.When heating medium in salt bath outwards flows out along electrode, encounter watercooling jacket and namely solidify, thus avoid leakage salt.Wherein, electrode adopts embed type flat manner, can ensure that the work-ing life of electrode is longer.The bottom land of described electrode and described salt bath forms the interval of 55-70mm, to avoid causing electric pole short circuit due to slag deposits.This kind of salt bath furnace with submerged electrodes can be used for the thermal treatment such as quenching, annealing, tempering, cyaniding, the timeliness heating of carbon steel, steel alloy, tool steel, die steel and aluminium alloy etc., slight oxidization heating when also can be used for steel precision fork.
This kind of salt bath furnace with submerged electrodes is provided with extraction hood and ventilates, and avoids the steam of heating medium to cause detrimentally affect to human body.This kind of salt bath furnace with submerged electrodes is provided with temperature alarming device and monitors in-furnace temperature, improves production security.
The invention has the beneficial effects as follows: a kind of salt bath furnace with submerged electrodes of the present invention, heat up rapider, start time is shorter, and rate of utilization is high, and thermosteresis is little, electric energy and furnace building material can be saved, electrode life is long, can reduce furnace outage time, and in-furnace temperature is more even, be conducive to the quality of production improving processing work, and can production safety be ensured.
