Abstract
The utility model provides a refining furnace of calcium aluminum core wire absorption rate can be improved and silk system is fed, belongs to the smelting technique field of metal for solve the problem that the heart yearn absorption rate is low of molten steel, its technical scheme is, it is including feeding the silk machine, feed a wire conduit and a pipe lifting support, feeding the wire conduit and including vertical pipe and two racecourse bends, two racecourse bends are fixed on pipe lifting support, their the inlet wire high difference of end and corresponding with the outlet of feeding silk machine side portion, the two leading -out terminal all with vertical pipe on the incoming line be connected. The utility model discloses set up two racecourse bends of the high difference of inlet wire end, can adjust the height of vertical pipe through switching the racecourse bend, made vertical pipe lower extreme remain throughout at best within range to the distance of molten steel liquid level to improve the heart yearn absorption rate of molten steel, reduced the smelting cost of steel.
Description
Technical field
The utility model relates to a kind of equipment for cored-wire or aluminum steel being sent in molten steel, belongs to the technical field of smelting of metal.
Background technology
Cored-wire hello the silk system of LF refining furnace is the visual plant in converter-refining-continuous casting production link.Its effect is molten steel inside of cored-wire or aluminum steel being made a gift to someone fast, reaches deoxidation, desulfurization, is mingled with the object of sex change and trimming.Cored-wire is fed silk system and is mainly comprised wire feeder, line feeding conduit and conduit lifting support (referring to Fig. 1), its working process is: compress between Wire Wheel cored-wire or aluminum steel being sent into wire feeder, when Wire Wheel rotates, the frictional force relying on two Wire Wheels to produce draws cored-wire by line feeding conduit quick inserting people molten steel, to reach the object of external refining.The line feeding conduit that silk system fed by existing cored-wire is made up of racecourse bend and vertical conduit, and the middle part of racecourse bend is fixed on conduit lifting support, and its end of incoming cables is relative with the line outlet of wire feeder sidepiece, and leading-out terminal docks with the upper end of vertical conduit.Too many owing to feeding the line outlet that can not depart from wire feeder in the end of incoming cables of racecourse bend in silk process, the length that therefore vertically conduit inserts ladle almost can not regulate, and vertical conduit lower end determines to the distance of liquid steel level primarily of the headroom of ladle.Because vertical conduit lower end directly to affect the specific absorption of calcium aluminum steel to the distance of liquid steel level, and Steel ladle clearance extremely unstable in actual production process, cause the specific absorption of calcium aluminum steel widely different, when headroom is large, the calcium aluminum steel specific absorption of molten steel only reaches 16%, not only have a strong impact on steel quality, and cause the waste of calcium aluminum steel, add the smelting cost of steel.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of refining furnace improving calcium aluminum core line specific absorption to feed silk system, to improve steel quality, reduces smelting cost.
Problem described in the utility model realizes with following technical proposals:
Silk system fed by a kind of refining furnace improving calcium aluminum core line specific absorption, formation comprises wire feeder, line feeding conduit and conduit lifting support, described line feeding conduit comprises vertical conduit and two racecourse bends, two racecourse bends are fixed on conduit lifting support, their end of incoming cables height is different and corresponding with the line outlet of wire feeder sidepiece, and the leading-out terminal of the two is all connected with the incoming line of vertical conduit upper end.
Silk system fed by the above-mentioned refining furnace improving calcium aluminum core line specific absorption, and described racecourse bend be adapter bonnet near a section of wire feeder, and along the direction of close wire feeder, its diameter becomes large gradually.
Silk system fed by the above-mentioned refining furnace improving calcium aluminum core line specific absorption, and the difference of altitude of two racecourse bend ends of incoming cables is 200mm.
The utility model is provided with two different racecourse bends of end of incoming cables height, the height of vertical conduit can be regulated by switching racecourse bend, vertical conduit lower end is made to remain in optimum range to the distance of liquid steel level, thus improve the heart yearn specific absorption of molten steel, reduce the smelting cost of steel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation that silk system fed by traditional refining furnace;
Fig. 2 is structural representation of the present utility model.
In figure, mark is as follows: 1, wire feeder, and 2, racecourse bend, 3, conduit lifting support, 4, vertical conduit.
Embodiment
Referring to Fig. 2, the utility model comprises wire feeder 1, two racecourse bends 2, conduit lifting support 3 and vertical conduit 4.When the improvement of racecourse bend can ensure that larger change appears in molten steel headroom, within vertical conduit 4 remains at optimum range (300-400mm) apart from the distance (namely inserting the degree of depth of molten steel) of liquid steel level bottom, thus improve heart yearn specific absorption.Conduit lifting support 3 comprises support body and slide block, and slide block is arranged on support body by vertical slideway, between slide block and support body, be provided with locking mechanism.Two racecourse bends 2 are fixed on slide block, just can be changed the height of racecourse bend 2 and vertical conduit 4 by the height of adjusting slider.The leading-out terminal (lower end) of two racecourse bends 2 is all connected with the upper end of vertical conduit 4, and the inwall of tie point should be enough round and smooth, ensures that high calcium aluminum core line can both slip into vertical conduit 4 after entering any one racecourse bend 2 smoothly.The end of incoming cables (upper end) of two racecourse bends 2 is designed to bell mouth shape (adapter bonnet), is convenient to entering of high calcium aluminum core line.
The utility model makes the racecourse bend 2 that silk system fed by traditional refining furnace into upper and lower two, and the end of incoming cables distance of upper and lower two racecourse bends is 200mm.If Steel ladle clearance is in normal range (300-400mm), need first to adjust conduit lifting support 3 during feeding heart yearn, the incoming line of one that makes position in two racecourse bends 2 lower aims at guide deflection sheave outlet (line outlet) of wire feeder 1, within now vertically conduit 4 remains on optimum range (300-400mm) apart from the distance of liquid steel level bottom, heart yearn is exported by the guide deflection sheave of wire feeder 1, inserts in molten steel successively through racecourse bend 2 and vertical conduit 4; If Steel ladle clearance comparatively large (500-600mm), need first to adjust conduit lifting support 3 during feeding heart yearn, the incoming line of one that makes position in two racecourse bends 2 higher aims at the guide deflection sheave outlet of wire feeder 1, within now vertically conduit 4 is adjusted to optimum range (300-400mm) apart from the distance of liquid steel level bottom, calcium aluminum steel specific absorption can rise to 22.85%.In actual production, the molten steel headroom of nearly 20% is large, and the every stove of molten steel that after transformation, headroom is large can save 35 meters of calcium aluminum steels.Namely reduce steel-making cost, improve again the castability of molten steel.
