Description
Technical field
This utility model is related to a kind of slag skimmer, the slag iron in more particularly, to a kind of iron storage type iron tap channel tap drain for blast furnace
Detached slag skimmer, belongs to metallurgy industry.
Background technology
Slag skimmer is to be placed on the part playing slag sluicing system effect in tap drain during blast furnace casting, and molten iron density ratio slag is big, ferrum
Water flows out from slag skimmer lower passage, and scum is located at top and flows out from slag runner mouth, has thus reached the purpose of slag sluicing system, but
Slag skimmer is frequently washed away during tapping a blast furnace, and bottom slowly eats away rear passage more and more higher, when highly high to certain
After degree, slag liquid will flow in molten iron together with molten iron, leads to hot metal composition unqualified, there is no that what is easy to handle at present
Method is keeped in repair to slag skimmer, and mostly can only stop maintenance whole piece tap drain, even if at this moment tap drain other position can also use, this
Result in tap drain asynchronous with the slag skimmer life-span, produce very big waste.
Slag skimmer accounting in tap drain refractory consumption rate amount is little, but governs the life-span of tap drain, if due to skimming
The device life-span can not be synchronous with tap drain, will result in the significant wastage of resistance to material.
Utility model content
This utility model be directed to the deficiencies in the prior art, there is provided one kind greatly prolong slag skimmer service life it is ensured that
Blast furnace normal production, produce very big economic benefit prolongs long-life iron storage type ditch slag skimmer.
For realizing this utility model purpose, there is provided technical scheme below: one kind can prolong long-life iron storage type ditch skimming
Device, described slag skimmer is located at iron tap channel tap drain tail end, and described slag skimmer front side top offers slag runner, slag skimmer bottom and bottom of trench
Constitute and Tie Tong road it is characterised in that slag skimmer includes square matrix, matrix is provided with and can move up and down near the one side of slag runner
Movable block, movable block one surface is provided with strip dovetail projection, strip dovetail projection be opened in matrix near the one of slag runner
The dovetail groove in face connects, and dovetail groove bottom separates between the upper and lower and is provided with counter sink, and strip dovetail projection offers through hole, in through hole
It is provided with fire resisting column, fire resisting column is pinned at countersunk head in the hole, adjust the upper-lower position of movable block.
Preferably, matrix bottom offers trapezoidal overcurrent mouth, in matrix, offer square cavities, square cavities with trapezoidal
Overcurrent mouth upper surface connects, and is cast with high intensity crack resistence pouring layer in square cavities.
Preferably, movable block bottom is socketed with zirconium matter set.
Preferably, movable block thickness determines according to tap drain remnants situation.
This utility model beneficial effect: greatly prolong slag skimmer service life it is ensured that blast furnace normal production, produce
Very big economic benefit.
Brief description

Specific embodiment
Embodiment 1: one kind can prolong long-life iron storage type ditch slag skimmer, described slag skimmer 1 is located at iron tap channel tap drain tail end,
Described slag skimmer 1 front side top offers slag runner 2, and slag skimmer 1 bottom and bottom of trench 3 constitute and Tie Tong road, and slag skimmer 1 includes square
Matrix 1.1, matrix 1.1 is provided with movable block 4 moving up and down near the one side of slag runner 2, and movable block 4 one surface is provided with bar
Shape dovetail projection 4.1, strip dovetail projection 4.1 is connected with the dovetail groove 1.1.1 being opened in the one side near slag runner 2 for the matrix 1.1,
Dovetail groove 1.1.1 bottom surface is spaced apart up and down and is provided with counter sink 1.1.2, and strip dovetail projection 4.1 offers through hole 4.2, through hole
It is provided with fire resisting column 5 in 4.2, fire resisting column 5 is pinned in counter sink 1.1.2, adjust the upper-lower position of movable block 4.Matrix 1.1 bottom
End offers trapezoidal overcurrent mouth 1.1.3, offers square cavities, square cavities and trapezoidal overcurrent mouth 1.1.3 upper table in matrix 1.1
Face connects, and is cast with high intensity crack resistence pouring layer 1.1.4 in square cavities.Movable block 4 bottom is socketed with zirconium matter set 6.Activity
Block 4 thickness determines according to tap drain remnants situation.
Show in Fig. 3, uneven below the slag skimmer after life-time service, cannot use greatly very much from bottom space,
By installing movable block additional in side, can solve slag skimmer and cross slag problem, slag skimmer movable block adopts preforming pre- simultaneously
First toast, can come into operation after installing, without continue baking, greatly ensure that blast furnace normal production, produce very
Big economic benefit.
