Description
[technical field]
The utility model relates to the technical field of refractory material, the technology of especially a kind of preforming blast furnace stemming is led
Domain.
[background technique]
Blast furnace taphole is in long-term smelting production, and due to bearing to wash away for a long time and corrode, tapping hole bosh gas index is thinning,
It forms local anomaly to corrode, cupola well water temperature difference, heat flow rate per unit area and temperature are easier to occur higher in normal point near iron mouth, lead to furnace
Cylinder side wall temperatures increase.In order to make iron mouth stable working state, meet the needs of intensification of smelting process in BF, it is desirable that the operation of stemming
Property, volume stability and opening performance to get well, and stemming used by current large and medium-sized blast furnace is not easily accessible clay gun, scum holds
Easily spilling, tapping duration are short, therefore are not able to satisfy the demand that modernization is smelted.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of preforming blast furnace stemming,
Stemming prefabricated component can be made to be easier to enter in clay gun, volume stability is good, is not easy craze and transfiguration, and sealing effect is strong, conducive to pushing away
Wide application.
To achieve the above object, the utility model proposes a kind of preforming blast furnace stemmings, including screw thread guide post, big gun
The bottom of stemming cylinder is arranged in mud cylinder and thread groove, the screw thread guide post, and the top of stemming cylinder is arranged in the thread groove
Portion is axially provided through structure through-hole in the stemming cylinder, and the structure through-hole runs through screw thread guide post, the screw thread vertically
Multiple deflector holes are provided in the middle part of the side of slot, the deflector hole is connected in the bottom part down of thread groove with structure through-hole.
Preferably, the shape of the screw thread guide post is cone, uniformly it is surrounded on the lateral surface of screw thread guide post
First flank, the shape of the stemming cylinder are cylinder, and the thread groove is cone-shaped groove, the inside of the thread groove
The second flank of occlusion corresponding with the first flank is provided on face.
Preferably, being provided with multiple through flow holes on the stemming column side face, the through flow hole is connected with structure through-hole
Logical, the through flow hole is uniformly circumferentially positioned on stemming cylinder, and the through flow hole is cylindrical hole.
Preferably, the axle center of the screw thread guide post, stemming cylinder and thread groove is located along the same line, the structure is logical
Hole is arranged on axial line, and the deflector hole is connected with the top of structure through-hole.
The utility model has the beneficial effects that the utility model is by the way that screw thread guide post, stemming cylinder and thread groove to be incorporated in
Together, by assay optimization, conical guide post can make stemming prefabricated component be easier to enter in clay gun, tie on stemming cylinder
Structure through-hole, through flow hole and deflector hole, which are worked in coordination, can guarantee preferable gas permeability, be not easy craze and transfiguration, when screw thread guide post and spiral shell
Groove it is engaged through the thread when, deflector hole is blocked, and then keeps through flow hole top airtight, promotes overall tightness, is conducive to
Installation, can make stemming prefabricated component be easier to enter in clay gun, and volume stability and opening performance are good, be not easy craze and transfiguration, benefit
In popularization and application.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
