It is good.
Since interior stick outer pipe type consutrode and slag bath form compound short net by cable and transformer, magnetic field is mutually supported
Disappear, short net induction reactance is reduced, and power factor can be made to improve 0.9 or so, and compared with single-phase single electrode, because of electric current when same power
Half is reduced, reduces network re-active power, to reduce power consumption.
The cooling water recirculation system includes positioned at 13 side of crystallizer crystallizer water inlet 12 setting up and down and crystallization
Device water outlet 11, crystallizer cooling water carry out cooling water circulation generally by the way of low in and high out, and cold water is from lower part crystallizer
Water inlet 12 enters, and spreads then up, flows out after heat absorption from top crystallizer water outlet 11；It further include being located at 13 side of crystallizer
The crystallizer wall cooling water seam 14 of wall, crystallizer wall cooling water seam 14 is around the wall of cup of entire crystallizer 13, in this case cooling
Water is equivalent to enter after will surround the entire cylindrical side wall of crystallizer 13, be used for cooler crystallizer 13.Cooling water and knot
Across one layer of crystallizer wall between slag bath, steel ingot inside brilliant device.
Preferably, a bottom water case can also be set on the lower section of crystallizer 13, operating platform 10, for crystallizer 13
Bottom cool down.
Working principle of the present invention is as follows: in esr process, slag charge is put into crystallizer, slag charge can be fallen at this time
Enter crystalliser feet.Interior stick outer pipe type consutrode is inserted into slag charge, the starting the arc, slagging operation are carried out.When slag charge becomes to melt
When the slag bath of state, at 10mm~50mm inside interior stick outer pipe type consutrode insertion slag bath, starting transformer is powered
It smelts.During the energization, slag bath generate Joule heat by consutrode end melt (entire slag bath has electric current to pass through, except with
Consutrode contact position generates Joule heat, and entire slag bath can all generate Joule heat, but the Joule heat of contact position is maximum, because that
In highest current density.Wherein consutrode resistance is smaller, and the Joule heat of generation can be ignored), drop is become by solid-state,
It across slag bath, falls into and forms metal bath in crystallizer, and be quickly solidified to form steel by the effect of cooling recirculation system simultaneously
Ingot.Meanwhile metal bath carrys out slag bath jack-up, slag bath floats to crystallizer top.
Compared with an ordinary electrode melts drippage, the drippage range of interior stick outer pipe type consutrode is bigger, the liquid of drippage
It drips also more.In smelting process, the smelting of the rodlike consutrode of internal layer and outer layer tubulose consutrode be it is the same, be only switched on
Mode is different, and electric current is flowed into from the rodlike consutrode of internal layer, passes through slag bath, flows out from outer layer tubulose consutrode.During this,
Interior stick outer pipe type consutrode and slag bath form compound short net and current loop by cable and transformer, shorten short net length,
Short net induction reactance is reduced, electrical efficiency is improved.
The interior stick outer pipe type bipolar series electroslag remelting device, using double consutrodes connect, burn-off rate is fast, electric current from
The rodlike consutrode of internal layer flows into, and passes through slag bath, flows out from outer layer tubulose consutrode, and slag temperature is more evenly distributed, heating effect
It is good.Equipment is simple simultaneously, easily operated, shortens short net length, to reduce short network pressure drop, the magnetic conduction steel knot that short net passes through
Component is reduced, and improves electrical efficiency and service life.
