As preferably, be provided with the calrod corresponding in the said molten metal case with metal pat.Be used for the heating of metal liquid layer, make metal pat keep liquid.
As preferably, be provided with the thermopair that contacts with metal pat in the said insulation metal box.This thermopair is connected with outside temperature control unit, is used for controlling automatically the temperature of metal pat, makes the homo(io)thermism of metal pat.
As preferably, the bottom of said molten metal case is provided with the copper coin that is connected with the transformer secondary output electrode.Import electric current in the molten metal case through it.
As preferably, be equipped with deflector roll corresponding above the both sides of said molten metal case with steel band, the central authorities of said molten metal case are provided with the pressure roller corresponding with steel band, and said insulation metal box is provided with compressed air cylinder, and said pressure roller is connected with compressed air cylinder.Compressed air cylinder control pressure roller moves up and down, and is used for being pressed into steel band in the metal pat, thereby has guaranteed that steel band contacts conduction with metal pat.
As preferably, the top of the deflector roll at said rear portion is provided with corresponding with the steel band molten metal roller of scraping.Guaranteed the cleaning of steel band.
As preferably, said insulation metal box is provided with infrared thermometer.Be used for measuring temperature of steel strips, infrared thermometer is connected with outside temperature control unit, can guarantee to be controlled at steel band austenitizing temperature scope to the temperature of steel band automatically.
As preferably, said insulation metal box is provided with protection gas and feeds mouthful.Prevent steel band and metal pat oxidation.
As preferably, the afterbody of said insulation metal box is provided with the equal incubator corresponding with steel band.Make the temperature of steel strips after the heating more even.
Beneficial effect:
The present invention adopts technique scheme that a kind of direct electric heating device of steel band of molten metal electrode is provided, and the pyritous metal pat contacts well with steel band, and conductivity is good; Therefore can not produce electrical spark between them; Because steel band is soft the contact with metal pat, just can not pull steel band, this apparatus structure is simple; Easily manufactured, thermo-efficiency can reach 90-95%.
