Abstract
The utility model relates to a liquid iron desulfuration lime discharging pipe which comprises a base (4), wherein a ladle weld pool (3) is arranged on the base (4); a stirring head (2) is arranged above the ladle weld pool (3) and is immersed into the ladle weld pool (3); a lime discharging pipe (1) is arranged on the inclined upper side of the ladle weld pool (3) and is straight through; and an elbow (5) is arranged at the material discharging end of the lime discharging pipe (1). According to the liquid iron desulfuration lime discharging pipe, the elbow is arranged at the material discharging end of the lime discharging pipe; when a material is stirred and fed, lime can be used for avoiding the stirring head and be all can be added into liquid iron instead of being adhered to the stirring head; and therefore, the service life of the stirring head is prolonged, and the lime consumption is reduced.
Description
Technical field
The utility model relates to a kind of desulfurizing iron lime tremie pipe, belongs to the steel smelting equipment technical field.
Background technology
In smelting iron and steel is produced, desulfurizing iron is a kind of hot metal in steelmaking pretreatment process, it immerses hot metal ladle molten bath certain depth with stirring-head, the whirlpool that utilization produces under the effect of large stirrer high degree of agitation, make calcium oxide or carbide of calcium base desulfurization powder and the abundant contact reacts of molten iron, reach the desulfurization purpose.
Common desulfurizing iron lime tremie pipe is through-type, and when stirring when reinforced, quite a few lime can be added on the stirring-head, and lime can be attached on the stirring-head work-ing life that therefore can reduce stirring-head, the consumption of increase lime with after molten iron contact.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of lime can not be attached on desulfurizing iron lime tremie pipe on the stirring-head.
The purpose of this utility model is achieved in that
A kind of desulfurizing iron lime tremie pipe, comprise base, be provided with the hot metal ladle molten bath on the described base, the top in described hot metal ladle molten bath is provided with stirring-head, described stirring-head immerses the hot metal ladle molten bath, the oblique upper in described hot metal ladle molten bath is provided with a lime tremie pipe, and described lime tremie pipe is through-type, is characterized in: the discharge end of described lime tremie pipe is provided with a bend pipe.
Compared with prior art, the beneficial effects of the utility model are:
A kind of desulfurizing iron lime of the utility model tremie pipe, the discharge end of its lime tremie pipe is provided with a bend pipe, when stirring is reinforced, lime can be avoided stirring-head, all is added in the molten iron, can not be attached on the stirring-head, therefore in the work-ing life that can improve stirring-head, reduce the consumption of lime.
Description of drawings
Fig. 1 is a kind of desulfurizing iron lime of the utility model tremie pipe structural representation.
Among the figure:
Lime tremie pipe 1
Stirring-head 2
