Description
Technical field
The present invention relates to a kind of Ferrous Metallurgy equipment, what particularly relate to a kind of ladle draining sand mozzle and stuffing sand adds sand method.
Background technology
Stuffing sand, is ladle bottom mouth of a river packing material, can sinters at a lower temperature, meets steel face and can not sinter too thick, otherwise can not automatic casting.The kind of ladle self-opening rate and drainage material and quality, water steel bar part, ladle lining and workman operant level etc. relevant.Under the prerequisite that drainage material is optimized, the interpolation operation of stuffing sand just seems particularly outstanding to the impact of ladle self-opening rate.
The sand mode that adds of stuffing sand mainly contains throw-in type and honeycomb duct type two kinds.It is that the artificial method dropped into of stuffing sand is thrown into position, the ladle bottom mouth of a river that throw-in type adds sand, because its labour intensity is large, efficiency is low and uneasy congruent factor and being abolished gradually.The mode that current mozzle adds sand mainly contains tilting and rectilinear.Tilting to add sand mode is lift ladle with overhead traveling crane, makes ladle be 30 ° of inclinations, and mozzle oblique cutting enters the ladle bottom mouth of a river and carries out the operation of filling sand, though ladle tilts to be convenient to location to add sand, but layer of sand Density inhomogeneity, sand face is uneven, and this to add sand mode dangerous.Add sand facies ratio with tilting, vertical conduit formula adds sand makes stuffing sand even density, and sinter layer shape is complete, is more conducive to ladle from opening.But current vertical conduit adds sand, and there are the following problems, if 1 locates inaccurate meeting and causes stuffing sand to waste; 2, because conduit lower end is not fixed, when pulling up conduit, stuffing sand surface configuration can be destroyed; If stuffing sand circulation is not smooth in 3 pipes, when pulling up conduit, remaining stuffing sand outflow can destroy stuffing sand surface configuration; The improper meeting of stuffing sand surface configuration causes ladle self-opening rate to decline.
Summary of the invention
The object of the invention is to overcome that existing vertical conduit adds that the location that sand exists is inaccurate, the smooth and sand face of the stuffing sand circulation not defect such as rounding in pipe, provide one to improve ladle draining sand additive effect, improve the adding set of the stuffing sand of ladle self-opening rate.
To achieve these goals, the invention provides a kind of ladle draining sand mozzle, described mozzle 8 comprises: funnel 1, hollow metal pipe 2, pendulum 3, support 4, suspension ring 5, hinge 6; Described funnel 1 is positioned at the top of described hollow metal pipe 2, in bell mouth shape, in the outer of described funnel 1, and symmetrical two described suspension ring 5; Described pendulum 3 is positioned on described hollow metal pipe 2, adopts described hinge 6 to be connected between described pendulum 3 with described hollow metal pipe 2, facilitates described pendulum 3 to swing and knocks described hollow metal pipe 2; Described support 4 is positioned at the afterbody of described hollow metal pipe 2, for the position of fixing described mozzle 8.
Preferably, described pendulum 3 is positioned at 1/3 place on described hollow metal pipe 2 top.
Preferably, described support 4 is corner support.
In addition, what present invention also offers a kind of stuffing sand adds sand method, and described method is based on the mozzle 8 of technique scheme, and described method comprises:
101) steel wire rope 9 is passed two suspension ring 5 on described mozzle 8, by pulley 11, described mozzle 8 is hung in ladle 7, controlled the lifting of described mozzle 8 by motor 14;
102) described pendulum 3 is connected with two described suspension ring 5 by fireproof line 10;
103) operating personnel add stuffing sand on the operational platform in described mozzle 8;
104) lift described fireproof line 10, described pendulum 3 beats described hollow metal pipe 2, prevents stuffing sand residual in pipe, formation sand face simultaneously;
105) when stuffing sands all in described mozzle 8 flow in ladle, add sand process and terminate.
The invention has the advantages that:
1, mozzle of the present invention is used for ladle draining sand adding procedure, can ensure the accurate input of stuffing sand, reduces stuffing sand use amount, improves ladle self-opening rate;
2, the bell mouth shape funnel of mozzle of the present invention can ensure stuffing sand noresidue in funnel, ensures the accuracy of stuffing sand addition;
Ears suspension ring on the funnel of 3, mozzle of the present invention, stably can sling mozzle and fall; Four foot supports bottom mozzle can the position of fixed diversion pipe, increases mozzle bottom heaviness simultaneously, stablizes center of gravity; Knocking mozzle by using the pendulum of mozzle can ensure to manage interior residual without sand, and can formation sand face.
