Description
Technical field
the utility model belongs to the desulfurizing iron apparatus field, relates in particular to a kind of air-cooled Cyclonic magnesia mixture desulphurization spray gun.
Background technology
from the 1950's, development is widely used external desulfurization of hot metal blowing desulfurization technology so far.This technology can adapt to various sweetening agent preferably, gives full play to the sweetening power of sweetening agent, reaches good sweetening effectiveness.
molten iron desulfuring spray gun generally partly is comprised of core jet pipe, pillar, refractory masses etc., by injection tube quantity, substantially can be divided into two kinds, single channel type and multiple flow passages type.Existing spray gun is because the winding-up rabbling door concentrates on gun head substantially, and it can not effectively destroy the winding-up bubble of rising, and spray orifice easily stops up and is difficult to safeguard and processes, and lance head is deteriorated, and reduce work-ing life.In addition, due to desulphurization spray gun, when in running order, inhomogeneous because of the internal temperature field distribution, differing materials is affected by the factor such as stress conduction to cause rifle body refractory materials cracking to come off.Some gun heads, with a sweetening agent vaporizing chamber, to strengthen the vaporization effect of sweetening agent, improve desulfuration efficiency, but, because vaporizing chamber is larger, the pressure that it has reduced nozzle, are easy to form large bubble, causes the melt splash.
Summary of the invention
the utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, is convenient to safeguard, can effectively reduce melt splash in the desulfurizing iron process, improves the rifle body stress and distributes, a kind of air-cooled Cyclonic magnesia mixture desulphurization spray gun that desulfuration efficiency is high.
for solving the problems of the technologies described above, the utility model is to realize like this.
a kind of air-cooled Cyclonic magnesia mixture desulphurization spray gun, it comprises core jet pipe, air-cooled cyclone stirring pipe, refractory masses, pillar and skeleton; Described refractory masses is assigned in the outside of air-cooled cyclone stirring pipe; Described core jet pipe is placed in air-cooled cyclone stirring pipe; Described air-cooled cyclone stirring pipe is set in pillar; Described skeleton is positioned at refractory masses and is fixedly connected with the outer wall of pillar; Outer wall at described core jet pipe is fixed with the vortex sheet.
as a kind of preferred version, skeleton described in the utility model can adopt transverse annular muscle and longitudinal rib to intersect fixedly reticulated structure.
as another kind of preferred version, the bottom of core jet pipe described in the utility model is fixed with vaporizing chamber.
the utility model is by the structures such as vortex sheet that are fixed with at the fixedly sleeved air-cooled cyclone stirring pipe of core jet pipe central region and core jet pipe outer wall, the vortex effect of the air-flow of can realizing jetting.Desulfurization powder, forms downward jet and causes bubble floating on backward from gun head spray orifice ejection through core jet pipe, and the sulphur in molten iron is deviate from bubble sweetening agent and melt effect in floating-upward process.Air-cooled cyclone stirs gas and sprays from jet pipe, the floating of dusting bubble smashes and slows down ascent rate, can adopt vortex effect simultaneously due to airflow passes vortex sheet the time, the winding-up air-flow is under the effect of vortex effect, the desulfuration efficiency of sweetening agent greatly improves, in addition, the winding-up air-flow flows and also can play cooling effect to metal gun core in air-cooled cyclone stirring pipe.
