The lead screw through the speed reducer at the low -down helical motion of the drive of motor, the slip cap slides on the lead screw simultaneously, through the pulling swing rocker I and pull swing rocker II of both sides, drives slider I and the slider II be connected with the spray gun and slides in the spout of saddle both sides to make spray gun I and spray gun II swing with certain angle round rotation support I and rotation support II respectively. The utility model discloses can enlarge the desulfurization scope under the condition that does not change torpedo jar mouth size of a dimension, effectively improve the reversion phenomenon that single spray gun blowing desulfurization caused, improve desulfurization efficiency and desulfurization quality, reduce the desulfurization cost, can be at each big popularization and application of steel plant.
Description
Technical field
The utility model relates to a kind of molten iron desulfuring spray gun device, belongs to technical field of metallurgical equipment.
Background technology
Along with the high speed development of social economy and Iron And Steel Industry, society is more and more higher to the requirement of steel quality, more and more harsher, economical and efficiently molten iron pretreatment desulfurizing become one of judgment criteria important in modern steel industry.Over nearly 30 years, Desulphurization of Pig Iron develops rapidly, now existing more than ten kind for the treatment of process, and wherein blowing process is one of most widely used method.At present, the blowing process of domestic employing mainly by sweetening agent as magnesium, carbide of calcium etc. are vertically sprayed in molten iron by the single spray gun of torpedo tank deck and carry out desulfurization, this doctor treatment mechanical condition is poor, the overall stirring intensity of molten iron is not high, and the reason can not sunk due to the jet restriction of angle and sweetening agent, thus result in sweetening agent and do not arrive some regions all the time, after desulfurizing iron has operated, in these regions, molten iron can be diffused in whole fish torpedo ladle gradually, sulphur content in molten iron is gone up, cause reversion phenomenon, desulfuration efficiency and desulfurization quality all lower.
Summary of the invention
For the deficiencies in the prior art, it is simple that the utility model provides a kind of structure, and easy to maintenance, the molten iron desulfuring spray gun device that desulfuration efficiency is high, to solve the problems of the technologies described above.
The utility model is in order to reach above object, be achieved through the following technical solutions: a kind of molten iron desulfuring spray gun device is provided, this device is by the saddle be arranged on workplatform, and the power set be arranged on saddle, transmission mechanism and spray gun device composition, it is characterized in that: leading screw is for the helical movement under the drive of step-down gear at electric motor, slip cap slides on leading screw simultaneously, rocking bar I and traction swing rocking bar II is swung by the traction of both sides, the slider I that drive is connected with spray gun and slide block II slide in the chute of saddle both sides, thus spray gun I and spray gun II are swung at a certain angle around rotary support I and rotary support II respectively.
Described molten iron desulfuring spray gun device, it is characterized in that: described saddle is connected by elevating chain with the support on workplatform, when carrying out desulfurization, under saddle, general who has surrendered's spray gun I and spray gun II extend in molten iron, taken off saddle after sulphur to rise, in addition on saddle also with slide block and rotary support open holes.
Described molten iron desulfuring spray gun device, is characterized in that: described spray gun I and spray gun II do not move in same plane, spray gun I and spray gun II can be intersected and open and can not collide.
The beneficial effects of the utility model are: can when not changing fish torpedo ladle tank mouth size, expand desulfurization scope, effectively improve the reversion phenomenon that single spray gun blowing desulfurization causes, improve desulfuration efficiency and desulfurization quality, reduce desulphurization cost, can at each big steel factory propagation and employment.
