The specific embodiment
As shown in Figure 1, a kind of electroslag molten casting device that adds electromagnetic agitation that has, comprise power supply 9, consutrode 1, crystallizer and agitator, crystallizer comprises slag bath 3 and metal bath 5, crystallizer and magnetic stirrer are integrated, the cooling water that feeds in the crystallizer both had been used for ingot solidification, also be used to produce the coil cooling in magnetic field, simplified apparatus system architecture not only, and electromagnet can also be produced magnetic field and arrive the active region and pass the copper coin number of plies and reduce to one deck from three layers, can reduce greatly because the magnetic energy loss that the magnetic field kelvin effect causes, the crystallizer outer wall is with an annular magnet, annular magnet is positioned at 1/2 above position of crystallizer, is wound with coil on the iron core of annular magnet.
Cooling water is fed in the crystallizer from the cooling water inlet, Tong Dian electromagnet and coil 2 are not immersed in the cooling water simultaneously yet, in the slag bath 3 of crystallizer, put into thickness and be 180 millimeters electrode slag charge, mobile consutrode 1 immerses 30 mm depths in the slag, consutrode 1 energising, the beginning esr process, the steel ingot height rises to three of crystallizer height/for the moment in crystallizer, with the magnetic stirrer coil electricity, increase gradually by zero, when consutrode 1 melting end rises to the lower surface of magnetic stirrer, coil current also reaches the operate as normal value and is about 400 amperes, the consutrode 1 of fusing forms molten steel and drips, and enter slag blanket 3, add outside under the rotation electromagnetic field effect, molten steel drips and presents the helix mode and fall, enter in the steel ingot liquid pool, also enter the effective magnetic field active region of magnetic stirrer along with the rising of steel ingot liquid pool, the unloaded magnetic induction intensity in action center place that adds electromagnet is 380 Gausses, frequency is 15 hertz, electric current and rotating excitation field effect produce electromagnetic force and drive the molten steel rotation in the molten steel at this moment, the electromagnetic force driven vertical is in the evenly temperature of solidification front that flows of column crystal in this process, promote the field trash and the motion of air bubbles of solidification front, break simultaneously or the bending columnar dendrite, and richness amassed be distributed in the melt again in the alloying element solute of solidification front, broken dendrite fragment becomes the new nuclei of crystallization after entering melt, to cause the increase of equiax crystal quantity, this process lasts till that comsumable melt finishes, close the electroslag remelting power supply, treat to close the electromagnetic stirrer coil power supply after steel ingot solidifies fully, after steel ingot cools off fully, close cooling water, go out ingot again.
The principle that electromagnetic agitating technology improves the electroslag remelting refining efficiency is that the molten drop of comsumable melt is under the rotating excitation field effect, in non-conductive slag blanket, fall in the helix mode, with respect to the refining process that does not apply magnetic field, directly falls, the motion distance increases, increase with the relative velocity of slag blanket, remove abilities such as impurity, deep desulfuration thereby strengthened molten drop, can reach the effect that improves refining efficiency.
Quality problems at actual steel ingot all are position, middle and upper part or the two kinds of different solids junctions that appear at steel ingot, the present invention proposes applying rotating magnetic field and puts on above position, electroslag smelting casting crystallizer middle part or two kinds of different solids junctions, according to result of study proposition add function composite by electromagnetic stirring in diameter greater than the round ingot more than 350 millimeters and have the binding site of two kinds of different solids.
