Description
Technical field
It is particularly a kind of to be used for spraying magnesia powder at a high speed to vacuum melting furnace the present invention relates to a kind of Smelting magnesium industry
Magnesia lance driving device.
Background technology
In Smelting magnesium industry, the method for refining magnesium is a lot, such as under high temperature and vacuum condition, with the presence of calcium oxide
When, magnesium vapor is generated by Si reduction magnesia, is separated from each other with the solid silicic acid dicalcium (2CaOSiO2) of reaction generation, and
It is condensed to obtain Crystalline Magnesium.This high temperature and vacuum condition are exactly to utilize vacuum melting furnace, the molten bath injection high speed into smelting furnace
Magnesia powder, this just needs a kind of magnesia lance driving device.The purpose of magnesia lance driving device is exactly to be sprayed to vacuum melting furnace
Magnesium oxide powder, its operation principle are to vacuum melting furnace by high velocity inert gas fluxion strap dynamic oxidation magnesium dust continuous high speed
Injection.The operating efficiency that existing magnesia lance driving device refines magnesium is not high, and is easily destroyed vacuum while work continuously and melts
Furnace vacuum environment.
The content of the invention
Present invention aim to solve problem above, there is provided a kind of magnesia spray gun, be carried using vacuum melting furnace
It is true that vacuum melting furnace is not destroyed under the process condition for refining magnesium, while the operating efficiency for refining magnesium can be improved, and worked continuously
Altitude.
The technical scheme is that be so achieved：A kind of magnesia spray gun, is characterized in：Hanging including top
Ring, the fittings body of tubular, sealing nut, locking nut, tubulose upper cutting gun, attaching nut, tubulose lower gun body, the connecting bending of arcuation
Pipe；The lower end of bridge piece is welded on fittings body upper end, and suspension ring are linked together by the top of bolt and fittings body；Upper cutting gun
Including upper lance tube, the upper and lower part appearance of upper lance tube is equipped with screw thread, and the top of top screw thread is screwed under fittings body
In portion, top thread bush is equipped with sealing nut and locking nut, and appearance is cased with a length section hermetically sealed case pipe in the middle part of upper lance tube, close
Fixed between envelope outer tube and upper lance tube with connecting rib, upper lance tube lower thread is left hand thread, screws in attaching nut
Upper end, attaching nut upper end is left hand thread, and the lower end of attaching nut is right-handed thread；Lower gun body includes lower lance tube, under
The upper end of lance tube screws in the lower end of attaching nut, and the outer surface of lower lance tube is provided with brambles plate, then uniformly the circle of smearing one is resistance to
Fiery material.
Beneficial effect of the present invention：The present invention is with strong points, is refined primarily directed to vacuum melting furnace in magnesium apparatus to smelting
The lance driving device of magnesia powder is sprayed at a high speed in molten bath；Because lower gun body is connected through a screw thread, it is convenient to change, it is not necessary to changes whole
Gun body, cost are low；Because lower gun body is made of non-magnetic heat-resistance stainless steel, it is possible to used in electromagnetic induction furnace,
It is not afraid of damage；Because lower gun body is constructed using brambles plate, then sprayable refractory again, therefore refractory material is difficult for drop-off, prolongs
Lower gun body whole service life is grown；Spray gun integral installation is convenient, whole spray gun need to be only lifted into holder by suspension ring,
Tightening locking nut can install, and Fast Installation can be achieved；Because upper cutting gun has very long one section of hermetically sealed case pipe and sealing
Set coordinates, and to ensure not reveal, therefore spray gun moves up and down in predetermined stroke at work will not also destroy the true of smelting furnace
Altitude；Top of the invention uses big radian bridge piece, can reduce the abrasion of high-speed oxidation magnesium dust and tube wall, can extend company
Connect bend pipe service life.
