Abstract
The utility model provides a novel iron runner structure of turning round, including iron runner, with the hot metal bottle of iron runner intercommunication, the right angle corner of an iron runner is provided with buffers, buffers are the extension section of the right angle corner of the straight tube duan zaiyu hot metal export's of molten iron import straight tube section, the terminal wall of buffers sets up to the arc surface, the crossing department of buffers and hot metal export's straight tube section sets up circular arc chamfering. Simple structure, the preparation of being convenient for effectively reduces the molten iron to corner impact force, increase of service life.
Description
Technical field
This utility model is related to blast furnace discharge yard and makes field, more particularly, to props up iron runner.
Background technology
Blast furnace discharge yard is made up of tap drain, an iron runner, a slag runner, and an iron runner is connected with tap drain with a slag runner.Prop up iron runner one
As long, tap a blast furnace in particular by tank position, be limited by the terrain topology at blast furnace scene, much an iron runner be required for turning several
Individual curved get in hot-metal bottle, corner due to molten iron scouring force greatly, is caused corner to prop up iron runner and is corroded very serious, become
The principal element in restriction iron runner life-span, for solving this problem, a lot of producers do not have good method yet, at most can only turn
Use quality more preferable castable in crook is constructed, but effect still not good it is often necessary to repairings of stopping, not only affect steel mill
Normal production, and cause a ton steel refractory consumption to greatly increase, it is the problem comparing headache in industry.
Because corner is to change molten iron flow direction, molten iron impulsive force naturally can be very big, washing away than straight to refractory material
The iron runner of line style corrodes seriously very normally, if only considering to increase the class of resistance to material, is extremely difficult to Expected Results.
Utility model content
This utility model is directed to the deficiencies in the prior art, there is provided a kind of structure is simple, is easy to make, and effectively reduces molten iron
To corner impulsive force, new iron runner turning structure of the one kind increasing the service life.
For realizing this utility model purpose, there is provided technical scheme below: a kind of new iron runner turning structure, include propping up
It is characterised in that being provided with relief area at the right-angle turning of an iron runner, relief area is molten iron to the hot-metal bottle that iron runner is connected with iron runner
Extension at the right-angle turning of the straight length exporting with molten iron for the straight length of import, relief area end wall is set to circular arc
Face, relief area arranges circular arc chamfering with the intersection of the straight length of molten iron outlet.
Preferably, relief area bottom be set to gradually rise domatic, domatic angle of inclination is 15 degree.
Preferably, outward-dipping 5 ~ 10 degree of relief area side wall.
This utility model beneficial effect: this utility model is transformed to the structure of an iron runner corner, in molten iron import
Direction arranges the relief area of an extended pattern so that molten iron is slowed down after reaching this relief area, flows in corner after deceleration
Go out, the degradation degree of such ditch will substantially reduce, and arrange circular arc and fillet, prevent right-angle corner to be washed cracking, bottom surface
Certain gradient upwards is set, so that molten iron is preferably buffered.
Brief description
Fig. 1 is the schematic diagram of prior art.
Fig. 2 is top view of the present utility model.
Fig. 3 is the domatic schematic diagram in relief area.
Specific embodiment
Embodiment 1: a kind of new iron runner turning structure, the hot-metal bottle connecting with iron runner including an iron runner, an iron runner
It is provided with relief area 1, relief area 1 is the straight length 2 of molten iron import at the right angle of the straight length 3 exporting with molten iron at right-angle turning
The extension of corner, relief area 1 end wall is set to arc surface 1.3, the phase of the straight length 3 that relief area 1 is exported with molten iron
Circular arc chamfering 4 is set at friendship.Relief area 1 bottom is set to domatic 1.1 gradually rising, and domatic 1.1 angles of inclination are 15 degree.Slow
Rush area's 1 side wall 1.2 outward-dipping 5 ~ 10 degree.It is provided with several ball bumps 1.1.1 on domatic 1.1.
Claims (3)
1. a kind of new iron runner turning structure, the hot-metal bottle connecting with iron runner including an iron runner is it is characterised in that prop up iron runner
It is provided with relief area, relief area is the right-angle turning in the straight length exporting with molten iron for the straight length of molten iron import at right-angle turning
The extension at place, relief area end wall is set to arc surface, and relief area arranges circle with the intersection of the straight length of molten iron outlet
Arc chamfering.
2. new iron runner turning structure of one kind according to claim 1 it is characterised in that relief area bottom be set to by
Edge up high domatic, domatic angle of inclination is 15 degree.
