Particularly in metallurgy, form a kind of method of separating layer
The present invention relates to form a kind of a kind of method of separating layer, between the material that this separating layer is being soaked into mutually, deposited or boning mutually, particularly in metallurgy when contacting at least two kinds.
Often have such problem in metallurgical technology, promptly metallic solution condenses on the member of being made by sintered ceramic material regionally, perhaps forms the deposit of high aluminium content on member, and this will influence the function of member.Such member is fragment of brick, valve closure, sleeve or the immersion tapping hole that blows the porch such as coal gas.
When pouring into a mould, for example in band roller or double roller therapy, can run into same problem near the thin plate of whole size.At this moment, molten steel can condense or form the Al of high aluminium content on necessary limited part 2O 3Deposit, this will influence the quality of band steel significantly.
At " steel and iron " magazine 111(1991) the 37th page of No.6 described such method in to 43 pages, yet do not provided the solution to described problem.
Advise that in DE4141508 A1 the limited part that is positioned at the side of molten steel is made with sheet metal, these sheet metals can be by the magnetic field penetration of an inductor.Magnetic field induces electric current in molten metal, electric current causes a kind of additional heating to molten metal, should avoid molten metal condensing on confinement plate thus.Yet the induced electricity that flows to molten metal fails to be convened for lack of a quorum and causes interference to the structure organization of thin plate marginal zone, and this interference descends with quality and interrelates.
In patent application P4143049 early, a kind of device has been described, the pottery that is arranged with many minute apertures on the limited part that is in the liquation side on this device adds material, a kind of liquid is filled into this material, and this kind liquid forms thin film, can avoid liquation condensing on limited part.For same purpose, in patent application P4238036.7 early, advise, the confinement plate that adopts a kind of sintered ceramic material of energy eddy-current heating to make, this material links to the electromagnetic field of inductor.
The object of the present invention is to provide a kind of method, can avoid the mutual bonding between the material by this method, the bonding of particularly a kind of metallic solution and a kind of solid, thus make the relative motion of material become possibility.
Described purpose solves by claim 1.The vibration that imposes on single-piece or many materials has hindered the fixed mutually of storeroom.What at first adopt is ultrasonic vibration.
Layout of the present invention with arrange to draw by following claim with to the description of embodiment, be the embodiment that enumerates in the metallurgy here, yet the present invention is not limited to this embodiment, also can be applicable to other field.
Fig. 1 is the immersion tapping hole sketch of metallurgical tank;
Fig. 2 is a double roller therapy device sketch;
Fig. 3 is band roller subtraction unit sketch;
Fig. 4 is the another kind of device sketch that is used near whole size cast.
An immersion tapping hole 1 of being made by sintered ceramic material is installed in the bottom of a metallurgical tank 2.The passage 3 of immersion tapping hole 1 is used for the conducting molten steel.A ultrasonic generator 4 is placed on the immersion tapping hole 1, and it imposes on immersion tapping hole 1(as solid) frequency be greater than the mechanical oscillation of 20 KHzs.This vibration is transmitted in immersion tapping hole 1 on the inwall 5 of passage 3.Because dither has hindered the stop of liquation when contacting lastingly with inwall 5, so formed a separating layer between liquation that flows and the inwall 5 in passage 3.Avoided solid material (Al particularly by this separating layer 2O 3Particle) fixed on inwall 5.Avoided to cause the baking knot of the increase that passage 3 free cross-sections reduce thus.Because separating layer, the mobile performance of liquation also improves, because separating layer has reduced the friction between inwall 5 and the solution.The width of separating layer is in the mark order of magnitude of millimeter, for example at the order of magnitude of several μ m.
A ultrasonic generator 4 is drawn in immersion tapping hole 1 outside in Fig. 1 (left side).A plurality of such generators 4 can be arranged evenly in the periphery of immersion tapping hole 1 under the situation of needs.Generator 4 also can be arranged in the form of a ring around the periphery of immersion tapping hole 1.
Ultrasonic generator 4 or with the elongated portion that it links also can be installed in immersion tapping hole 1 inwall (referring to Fig. 1 or), it makes as the vibration of the liquation of fluid.Primary is the setting height(from bottom) of generator 4 on immersion tapping hole 1, on this height, exists formation Al according to experience 2O 3The trend of baking structure.Can avoid fixed on inwall 5 of the sedimental crystalline particle of growing by ultrasonic vibration.
Shown the rotating running roller 6,7 of the rightabout that is used for double roller therapy equipment among Fig. 2, carried out steel-sheet in this way near whole size cast.Molten steel is imported into running roller 6,7, and carries downwards in the interval that running roller 6,7 constitutes.Side for fear of molten steel is excessive partially, and it is other that confinement plate 8,9 is installed in running roller 6,7 as fixture.Install ultrasonic generator 4 on the confinement plate of being made by steel or sintered ceramic 8,9, as described above they force confinement plate 8,9 vibrations like that, and this has just hindered liquation condensing or constituting on confinement plate and has dried by the fire structure.
To using the equipment of band roller method shown in Fig. 3, consider to have arranged two drive roller wheel 10,11 to drive transport tapes 12.Solution is thin ribbon shaped and is poured into transport tape 12 in zone 13, and molten steel cools off on transport tape 12 until solidifying and being transmitted to be taken away.
Flow out side for fear of molten steel, has arranged restriction guide plate 14,15.Installing ultrasonic generator 4 on restriction guide plate 14,15, it forces 14,15 vibrations of restriction guide plate.Cause like this limiting guide plate 14,15(as fixture) and molten steel (as liquid) between separation, thereby molten steel can not condense on the restriction guide plate 14,15, the crystalline particle that contains in molten steel can not be deposited on the restriction guide plate 14,15 yet, does not have baking knot thing for this reason and generate on the restriction guide plate.
What the embodiment of Fig. 4 represented is that thin plate a kind of and shown in Figure 3 is near the similar equipment of whole size cast.Abandoned being driven the transport tape 12 that running roller 10,11 drives on the equipment of Fig. 4, substituted transport tape, considered to have arranged a plate of being made by steel or sintered ceramic material 16 that connects material, it is other that it is placed in rigid bearing 17,18.In plate 16 sides that connect material restriction guide plate 14,15 is installed.These restriction guide plates can make and connect material plate 16 one or be fixed on the plate 16 that connects material as separation member.
Below the plate 16 that connects material, settle a ultrasonic generator 4 at least, additionally can on restriction guide plate 14,15, arrange ultrasonic generator 4.Also can make restriction guide plate 14,15 obtain desirable ultrasonic vibration if be placed in the ultrasonic generator 4 of the plate 16 that connects material, the ultrasonic generator that then is positioned on the restriction guide plate can be cancelled.
For example molten steel flow to the zone 13 of the plate 16 that connects material from the sipes nozzle.Connecting material has an inclination angle W between plate 16 and the horizontal line H, its size should make the molten steel on the plate 16 that connects material be tilted to current downflow from zone 13.Ultrasonic vibration by dash receiver 16 and restriction guide plate 14,15, between these fixtures and molten steel, formed a kind of separating layer, this separating layer has hindered molten steel or their particle condensing or dry by the fire knot on connect material plate 16 and restriction guide plate 14,15, and also making molten steel simultaneously with respect to the plate 16 that connects material becomes possibility with the desirable motion that limits guide plate 14,15.
Solution mobile is provided with the plate 16 that connects material by inclination W angle and reaches in the embodiment of Fig. 4.
The discharging of liquation can improve on the plate 16 that connects material that a relative horizontal line H has an inclination angle W to place, when the ultrasonic vibration direction that puts on the plate 16 that connects material forced liquation to flow from zone 13 along direction F, the discharging of liquation also can realize on the plate 16 that connects material of a horizontal positioned.
The arrangement of described ultrasonic generator 4 also can be used for other member, as the valve closure of coal gas mouthpiece place's fragment of brick or metallurgical tank, to avoid condensing or the baking knot of high aluminium content impurity of on member liquation.
By selecting steel to soak into less its effect of agglomerated material with supported.
