Electric induction furnace goes out in the molten iron process whole, and a fluid stream and the drop point of molten iron are changing always.Its reason is: when converter nose moved up and down in casting cycle, drop point can change, and body of heater can change because of rotation makes the molten iron area of plane in casting cycle, and the variation of the molten iron area of plane also changes the iron flow of generation.Just often need position normally the carrying out of adjustment nodularization bag with the assurance nodularization because of the variation of molten iron a fluid stream.But the nodularization bag generally plays with driving when going out molten iron, and is also very unstable when driving is hung the nodularization bag through steel wire rope.Make the nodularization bag be difficult for remaining certain position relation, can cause the instability of nodulizer oxidation evaporation capacity like this, also directly affect the nodularization quality of spheroidal graphite cast-iron with the molten iron a fluid stream.
The problem that the bag method of using to above-mentioned casting molten iron at present of dashing exists is existingly fed the silk method or is added a cover method such as method in a small amount of application, but certain difficult popularization part is all arranged, so still be most popular method towards Bao Fa.
Summary of the invention
The purpose of this invention is to provide the tap a blast furnace guider of molten iron of a kind of electric induction furnace; This guider is when melting spheroidal graphite cast-iron; Can make the nodulizer eremacausis and reduce the nodulizer scaling loss, can make nodulizer oxidation stable evaporation capacity and improve the nodularization quality of spheroidal graphite cast-iron.
Technical scheme of the present invention is: the tap a blast furnace guider of molten iron of a kind of electric induction furnace.Two grate columns of fixed installation on the furnace wall, induction furnace body front on electric furnace converter nose both sides.Each installs a cross bar respectively the first half of two grate columns and Lower Half.The guide rail of two band grooves vertically is fixed in two crossbar end in both sides.Top at two grate columns all is equipped with bearing.Two forks of fixed installation on the bearing shell of two bearings, two forks can rotate around bearing.All have the fork elongated slot on two forks, be movably installed with straight pin in two fork elongated slots, straight pin can slide in the fork elongated slot.The vertical post of the slide plate frame of slide plate frame upper end is sleeved on the straight pin through vertical post cylindrical hole and can rotates around straight pin.The slide plate frame is also followed fork and is moved together.Have the hypotenuse installing hole on the two slide plate frame hypotenuses of slide plate frame.The transition converter nose through the hook movable set on the slide plate frame.The transition converter nose can move with the slide plate frame.Slide plate frame another side is connected with four rolling through two connecting plates.Four rolling is inlaid in respectively in the groove of two guide rails in both sides, and roller can drive the slide plate frame and the transition converter nose moves up and down along guide rail.
Transition converter nose inner ring is equipped with refractory masses as tapping a blast furnace molten iron flow channel.Transition converter nose epimere is the inclination runner, and this is peristome above inclination runner.This opening is in electric furnace converter nose below, and the molten iron that taps a blast furnace can flow in the inclination runner of transition converter nose when the electric furnace converter nose flows out fully.Transition converter nose hypomere is a cylinder vertically downward.The hole, hole is poured over against the molten iron of spheroidal graphite cast-iron in this cylinder lower end when the casting molten iron.
The induction furnace body rotation makes the electric furnace converter nose be moved down into the water level that taps a blast furnace and puts out molten iron when electric induction furnace goes out molten iron.Drive the transition converter nose and move down through fork, slide plate frame when induction furnace body rotates along guide rail.Electric furnace converter nose and transition converter nose are moved down into the water level that taps a blast furnace synchronously and put like this, and the transition converter nose remains certain distance until casting molten iron work completion with the electric furnace converter nose when the casting molten iron.Because transition converter nose hypomere is a vertical tube, make molten iron when flow is stablized, remain changeless drop point, promptly keep the constant and comparatively constant scouring force of direction of molten iron a fluid stream.Because the direction of molten iron a fluid stream is constant comparatively constant with scouring force, but only pouring in the molten iron hole, molten iron a fluid stream aligned position can not pour in the nodulizer hole, the nodularization bag just can fix a point to be placed in the tapping a blast furnace the position of ladle and need not use driving to suspend in midair like this.Nodulizer scaling loss amount will reduce when casting like this, and the nodularization quality is just more stable.Also because transition converter nose and molten iron contact area are little, thermal losses is also little.
Advantage of the present invention has provided the tap a blast furnace guider of molten iron of a kind of electric induction furnace; This guider is when melting spheroidal graphite cast-iron; Can make the nodulizer eremacausis and reduce the nodulizer scaling loss, can make nodulizer oxidation stable evaporation capacity and improve the nodularization quality of spheroidal graphite cast-iron.
