Description
Technical field
The utility model relates to a kind of desulfurizer of metallurgy industry, particularly relates to a kind of molten iron external refining pretreatment desulfurizing spray magnesium rifle.
Background technology
The defect at present at the molten iron outside-stove refining dephosphorization spray magnesium rifle that field of metallurgy uses, there is reaction chamber reaction violent, produce high-frequency vibration and high light, reaction chamber is cracked, fallen block.Its not only work-ing life short, plant factor is low, and production cost is high, also can cause damage to the clad of hot metal ladle.
Utility model content
The utility model technical issues that need to address are to provide one and alleviate chamber pressure, reduce magnesium in the explosion of reaction chamber, shake frequently and exciting force, reduce optic pollution and the damage to sweetener matching component, increase the integrity of reaction chamber, and then improve the life-span of spray magnesium rifle, improve the molten iron external refining pretreatment desulfurizing spray magnesium rifle of output.
For solving the problem, technical solution adopted in the utility model is:
A kind of molten iron external refining pretreatment desulfurizing spray magnesium rifle, comprise refractory masses, skeleton, supporting tube and be positioned at protective tube and the dischage tube of supporting tube, dischage tube is positioned at protective tube, refractory masses is positioned at outside supporting tube, skeleton is arranged in refractory masses, dischage tube, protective tube, supporting tube, skeleton and refractory masses are combined into gun body, inside, gun body lower end is provided with bell mouth shape reaction chamber, reaction chamber is provided with multiple through pore, the inside and outside wall of the through reaction chamber of through pore, described through pore is the through pore in the spout elevation angle obliquely; Be provided with gap between dischage tube, protective tube, supporting tube and be filled with lagging material.
According to the further preferred version of the utility model be: the tilt angle of described through pore namely and the angle of horizontal plane be between 30 ° ~ 55 °, its position is in the reaction chamber between 30 ~ 70mm apart from bottom face.
Further preferred version be the quantity of described through pore between 2 ~ 6, and be uniformly distributed, the aperture of through pore is between 25 ~ 80mm.
The beneficial effect adopting technique scheme to produce is: the utility model adopts the design of offering through pore on the inside and outside wall of reaction chamber, greatly reduce the spalling degree of the reaction that magnesium produces after reaction chamber contacts with molten iron, make operational process more steady, avoid reaction chamber owing to reacting acutely cause cracked and falling block, extend the desulfurization spray magnesium rifle life-span, improve hot metal output, reduce the consumption of magnesium, reach higher desulfurization index.
Accompanying drawing explanation

Fig. 2 is the cross sectional representation of pipe core part of the present utility model.
Wherein: 1, supporting tube, 2, refractory masses, 3, skeleton, 4, gun body, 5, reaction chamber, 6, through pore, 7, dischage tube, 8, protective tube.
Embodiment
Be described in further detail the utility model below in conjunction with accompanying drawing: as shown in Figure 1, it is a gun body 4 that the utility model comprises main body, and the inside, lower end of gun body 4 is reaction chamber 5.Gun body 4 comprises refractory masses 2, skeleton 3, supporting tube 1, protective tube 8, dischage tube 7.It is protective tube 8 outside dischage tube 7; it is supporting tube 1 outside protective tube 8; dischage tube 7 is positioned at protective tube 8, and dischage tube 7 and protective tube 8 leave gap, also leave gap between protective tube 8 and supporting tube 1, in these gaps all and be filled with slag or other lagging material.Refractory masses 2 is positioned at outside supporting tube 1, skeleton 3 is arranged in refractory masses 2, for main body, dischage tube 7, skeleton 3 and refractory masses 2 are combined into gun body 4 with supporting tube 1, gun body 4 lower end is provided with bell mouth shape reaction chamber 5, reaction chamber 5 is provided with multiple through pore 6, the inside and outside wall of the through reaction chamber of through pore 6, described through pore 6 is the through pore in the spout elevation angle obliquely.
According to the needs produced, the tilt angle of through pore 6 angle of horizontal plane (namely with) need be determined according to the molten iron height of the capacity and hot metal ladle of containing hot metal ladle, general control is between 30 ° ~ 55 °, and the position of through pore 6 in reaction chamber is between distance reaction chamber bottom face 30 ~ 70mm.The aperture of through pore 6 is also determine according to the capacity and molten iron height of containing hot metal ladle, and general aperture design is between 25 ~ 80mm.The pore quantity of through pore 6 is also according to containing the capacity of hot metal ladle and highly determine, generally design between 2 ~ 6, and the position of through pore being generally symmetrical arranged, and is uniformly distributed simultaneously.
When using this spray magnesium rifle, before hot metal ladle is stretched in the lower end of gun body, dischage tube starts to spray rare gas element, rare gas element can be argon gas, can prevent molten iron from decline process, entering reaction chamber at gun body, the gun body lower surface general distance bag end 200 ~ 300mm, then magnesium powder is sprayed into reaction chamber together with rare gas element in dischage tube 7, magnesium powder contacts with molten iron and vigorous reaction occurs in reaction chamber, impel the molten iron in reaction chamber to seethe and produce a large amount of gas, portion gas pours in the molten iron below reaction chamber with reaction impingement flow, portion gas enters in the molten iron on upper strata by through pore 6 simultaneously, two strands of gases stir the molten iron in hot metal ladle, desulfurization process can be accelerated, simultaneously, the vibrations of spray magnesium rifle reduce greatly, improve the work-ing life of spray magnesium rifle.
