Gun body includes lance tube, and the upper and lower appearance of upper lance tube is equipped with screw thread, and the top of top screw thread screws in fittings body
Bottom in, equipped with sealing nut and locking nut, in the middle part of upper lance tube, appearance is cased with a long section hermetically sealed case to top thread bush
Pipe, is fixed with connection gussets between hermetically sealed case pipe and upper lance tube, and upper lance tube lower thread is left hand thread, screws in and connects
The upper end of nut, attaching nut upper end is left hand thread, and the lower end of attaching nut is right-handed thread；Lower gun body includes lower spray gun
Pipe, the upper end of lower lance tube screws in the lower end of attaching nut, and the outer surface of lower lance tube is provided with brambles plate, then uniform application one
Circle refractory material.
This utility model beneficial effect：This utility model is with strong points, is primarily directed to vacuum melting furnace and refines magnesium apparatus
The middle lance driving device to smelting molten bath high velocity jet magnesia powder；Because lower gun body is threaded connection, change convenient it is not necessary to
Change whole gun body, low cost；Because lower gun body is made it is possible in electromagnetic induction furnace using non-magnetic heat-resistance stainless steel
Middle use, is not afraid of damage；Because lower gun body adopts brambles plate to construct, then sprayable refractory again, therefore refractory material is difficult
Come off, extend lower gun body whole service life；Spray gun integral installation is convenient, only by suspension ring, whole spray gun need to be lifted into handle
In holder, tightening locking nut can install, achievable Fast Installation；Because upper cutting gun has very long one section of hermetically sealed case pipe
With sealing shroud cooperation, to ensure not reveal, therefore spray gun moves up and down in predetermined stroke at work and also will not destroy melting
The vacuum environment of stove；This utility model top adopts big radian bridge piece, can reduce the mill of high-speed oxidation magnesium dust and tube wall
Damage, bridge piece service life can be extended.
