Abstract
The utility model discloses an external furnace iron melt desulfurizing device for magnesium based core-spun wires, which adopts a simple wire feeding machine and a magnesium based core-spun wire to replace a powder blowing system, wherein, the wire feeding machine is provided with a guide tube; the powder blowing system has the disadvantages of large investment and complicated equipment; the powder blowing system comprises powder spraying pot, a fluidized bed, a spray gun, etc. The utility model has the advantages of less investment, good effect, and convenient use and maintenance.
Description
The utility model relates to a kind of desulfurizing iron device, particularly a kind of external desulfurization of hot metal device that adopts magnesium base cored-wire as the desulfurizing iron medium.
In recent years, iron and steel domain begun one's study and this high efficiency furnace of magnesium base on probation desulfurization outside sulfur removal technology, but generally all be that winding-up contains magnesium pulvis such as CaC2, CaO and magnesium powder etc. to the molten iron depths, the injection system of this technology comprises equipment such as powder spraying pot, fluidized-bed, spray gun, the one-time investment of this serial equipment is very big, Processes and apparatus is comparatively complicated, up to the present, does not also utilize magnesium base cored-wire to carry out the device of external desulfurization of hot metal.
The purpose of this utility model is to provide a kind of less investment, working service to adopt magnesium base cored-wire to make the external desulfurization of hot metal device of desulfurization medium easily.
The purpose of this utility model is to realize by the magnesium base cored-wire external desulfurization of hot metal device of following structure, it comprises that feeding wire machine 3 that guide pipe 4 is housed and magnesium base heart yearn powder 8 are wrapped in the magnesium base cored-wire 2 within the outsourcing iron sheet 7, being installed on steelworks platform 1 leans on the heart yearn exit of the feeding wire machine 3 of rail one side that guide pipe 4 is installed, 4 one-tenth straight bent angles of guide pipe, the straight bent angle corner of guide pipe 4 is circular arc, the mouth of pipe of guide pipe 4 communicates with the outlet of feeding wire machine, magnesium base cored-wire enters feeding wire machine 3 from the heart yearn inlet of feeding wire machine 3, by feeding wire machine 3 magnesium base cored-wire 2 is delivered in the guide pipe 4, magnesium base cored-wire moves along guide pipe 4, is inserted in the molten iron downward vertically by the outlet of guide pipe 4.
The utility model has reduced investment by adopting one the feeding wire machine of guide pipe and the pulvis injection system that investment is big, equipment is complicated that a kind of magnesium base cored-wire has replaced current widespread use simply are housed, and uses, safeguards very convenient.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of external desulfurization of hot metal device;
Fig. 2 is the structural representation of magnesium base cored-wire.
By Fig. 1,2 as can be known, feeding wire machine 3 in the utility model be loaded on steelworks platform 1 by rail one side, the guide pipe 4 that is loaded on the feeding wire machine 3 communicates with the heart yearn outlet of feeding wire machine 3, the magnesium base cored-wire 2 that heart yearn powder 8 is wrapped within the outsourcing iron sheet 7 enters feeding wire machine 3 by the feeding wire machine inlet, and power is provided for magnesium base cored-wire 2 by feeding wire machine 3, magnesium base cored-wire is moved along guide pipe 4 inwalls, and to passing by the outlet of the lower end of guide pipe 4, and vertically insert in the molten iron of iron ladle 5, iron ladle 5 is placed on the rail car 6.
After hot metal mixer has gone out molten iron, there is the molten iron of certain sulphur content to pack in the iron ladle, be transported to a side of steelworks platform by the rail car, being loaded on the steelworks platform vertically inserts in molten iron with the wire-feeding velocity of 50m/min through 2 minutes magnesium base cored-wires with 100m by the feeding wire machine of rail one side, make it and the desulfurizing iron chemical reaction, reach the desulfurization purpose, outsourcing iron sheet 1 and unnecessary CaO, MgO still stay the process for making that participates in next stage in the molten iron.
Claims (1)
1, a kind of magnesium base cored-wire external desulfurization of hot metal device, it comprises feeding wire machine (3), it is characterized in that: basic cored-wire (2) is made up of outsourcing iron sheet (7) and the magnesium base heart yearn powder (8) that is wrapped within the outsourcing iron sheet (7), being installed on steelworks platform (1) leans on the heart yearn exit of the feeding wire machine (3) of rail one side that guide pipe (4) is installed, guide pipe (4) becomes straight bent angle, the straight bent angle corner of guide pipe (4) is circular arc, the mouth of pipe of guide pipe (4) communicates with the outlet of feeding wire machine, magnesium base cored-wire enters feeding wire machine (3) from the heart yearn inlet of feeding wire machine (3), by feeding wire machine (3) magnesium base cored-wire (2) is delivered in the guide pipe (4), magnesium base cored-wire is along guide pipe (4) motion, passed by the lower end outlet of guide pipe (4).
