The length of the upper support beam is greater than the length of the lower support beam. The utility model is used to repair the mold in a hot state in time for the local damage of the main iron groove due to cracking, peeling, erosion, etc.; when the repaired refractory castable is hardened to a sufficient strength, the mold can be removed, and can be repeated It avoids the failure to repair in time due to the serious damage of the main iron ditch, and the slag iron continues to erode and penetrate, resulting in the main iron ditch burning through accident, and prolongs the service life of the main iron ditch.
Description
Technical field
The utility model belongs to blast furnace field more particularly to a kind of main trough of blast furnace sectional repair mold in ironmaking.
Background technique
Main trough of blast furnace is the channel that slag iron is discharged in time, and with blast furnace enlargement and strengthening smelting, iron increases out, main
Iron runner use condition is increasingly harsh, and service life greatly affected the labor intensity of flushing and casting work, ton iron refractory material
Consumption, or even influence the normal production of blast furnace.
Currently, well known country's large blast furnace sow, typically uses low cement combination Al2O3-SiC-C fire proofed wood
Material, is formed using die casting.Since main trough of blast furnace by tapping discontinuity because being influenced, sow inner lining refractory by
There is the phenomenon that low intensity and explosion, explosion, in addition slag iron is washed away and corroded, so that the main iron of blast furnace in sometimes hot and sometimes cold impact
Ditch service life reduction limits sow and crosses iron, seriously restricts the normal production of blast furnace sometimes.
In addition, there are certain drops for main trough of blast furnace and iron mouth, and sow has certain gradient, because having in blast furnace
There is certain pressure, therefore there is certain kinetic energy at parabolic shape when slag iron is ejected from tapping hole into sow
And hydraulic coupling, the refractory material for falling position around iron spot is washed away, causes to fall and occurs dell around iron spot, master can be also burnt when serious
Iron runner.
In addition, the circulation that refractory material can bear 500 DEG C ← → 1500 DEG C of temperature is made in main trough of blast furnace use process
With this meeting is so that generate horizontal and longitudinal crack inside refractory material；The crackle of generation under the action of slag and molten iron along
Crackle corrodes, and generates groove, accelerates damage.
In addition, sow under the action of periodical high speed molten iron, deteriorates, position is mainly the slag for storing iron phase and tapping phase
There are two local excessive damage concave grooves in line position, so that slag lining damage is serious, and the damage of other positions is lighter,
Sow is caused integrally to damage unbalanced.
Utility model content
The purpose of this utility model is to provide a kind of main trough of blast furnace sectional repair mold, with solve in the prior art because
Sow local damage seriously fails to repair in time, slag iron continue corrode and permeate, and cause sow burn accident the problem of.
The utility model provides a kind of main trough of blast furnace sectional repair mold, the striker plate being oppositely arranged including two pieces and more
Root is connected to the support beam between two pieces of striker plates；The support beam is made of two beam arms being hinged.
In the main trough of blast furnace sectional repair mold of the utility model, it is provided with more reinforcements on the striker plate and draws
Muscle, horizontally disposed reinforcement lacing wire are mutually perpendicular to the reinforcement lacing wire being vertically arranged.
In the main trough of blast furnace sectional repair mold of the utility model, the both ends of the support beam are connected to two
On the reinforcing rib that two be oppositely arranged piece of block striker plate are vertically arranged, and support beam both ends are located at identical height.
In the main trough of blast furnace sectional repair mold of the utility model, the length for the support beam being disposed over is greater than
The length of the support beam of lower section.
In the main trough of blast furnace sectional repair mold of the utility model, the hinged of two beam arms of support beam is being constituted
End is equipped with slotted hole, by adjusting bolt fastening in slotted hole.
In the main trough of blast furnace sectional repair mold of the utility model, the striker plate upper end is equipped with hoisting ring.
In the main trough of blast furnace sectional repair mold of the utility model, the repairing mold is a kind of welding for steel structure
Part.
Compared with prior art, beneficial effect is the utility model:
1, it can be directlyed adopt to main trough of blast furnace local damage region after simply clearing up using tapping interval time
Hot patching, baking time is short, does not influence normal tapping, achievees the purpose that quick tapping.
2, damageable zone main for main trough of blast furnace is taken planned preventative sectional repair, is avoided because of main iron
Ditch local damage seriously fails to repair in time, and slag iron continues to corrode and permeate, and sow is caused to burn accident, extends sow
Service life.
3, the utility model only repairs main trough of blast furnace local damage position, where where damages repairing, other
Uncorroded intact part can still continue to use, and can substantially reduce refractory material cost.
4, the main trough of blast furnace repaired through the utility model, crossing iron by 100,000 tons increases to 200,000 tons；Sow work
Service life extends, and is increased to 30 days by 20 days.
