Abstract
It is the invention discloses a kind of synthesis repairing method of ladle liner brick：First according to the fact damaged situation of ladle liner, it is determined that needing the number of plies of working lining brick repaired；The residual steel waste residue and metamorphic layer of needing the working lining brick surface repaired are disposed；Orlop working lining brick to be repaired is excavated, the neutral position dug out is embedded in new brick, embedded new brick should protrude 40 ~ 60mm than upper strata working lining brick；It is close to working lining brick on the new brick of protrusion with the new brick of 40 ~ 60mm thickness to be subsidized successively from bottom to top, until the working lining brick for needing to repair is completely covered.Method for repairing and mending of the present invention is simple, reduces refractory consumption, due to that need not remove the brick body of damage completely, only need to remove the impurity on brick surface, one layer of splits is then directly pasted on top layer, repairing furnace outage time is substantially reduced, the use of material for repairing is saved；The lining brick damaged simultaneously reduces the generation for abandoning useless brick admittedly, is more favorable for environmental protection, there is good economic implications and social effect without removing.
Description
Technical field
The present invention relates to the maintenance of ladle liner, more particularly, to a kind of synthesis repairing method of ladle liner brick.
Background technology
Under normal circumstances, ladle liner brick uses certain phase, different degrees of erosion can all occurs, residue pile or
Other indivedual containment wall positions are more serious due to the erosion by slag or impulse ratio, can corrode than very fast, it is necessary to be individually replaced slag
Line brick or containment wall operational layer brick, the repairing method of use are all to remove the residue pile for damaging position to replace, the repairing side
Not only the used time is longer for method, and the useless brick pulled down also pollutes the environment, and adds maintenance cost.
The content of the invention
It is an object of the invention to provide a kind of synthesis repairing method of ladle liner brick, this method both saves material, again
Maintenance time can be greatly shortened.
To achieve the above object, the present invention can take following technical proposals：
The synthesis repairing method of ladle liner brick of the present invention, comprises the steps：
The first step, according to the fact damaged situation of ladle liner, it is determined that needing the number of plies of working lining brick repaired；
Second step, it would be desirable to which the residual steel waste residue and metamorphic layer on the working lining brick surface of repairing are disposed；
3rd step, orlop working lining brick to be repaired is excavated；
4th step, new brick is embedded in the neutral position dug out, and embedded new brick should protrude 40 ~ 60mm than upper strata working lining brick；
5th step, is close to working lining brick on the new brick of protrusion with the new brick of 40 ~ 60mm thickness and is pasted successively from bottom to top
Mend, until the working lining brick for needing to repair is completely covered.
It is magnalium chamotte bonding agent, raw materials used weight to be subsidized in 5th step with the binding agent between new brick and working lining brick
It is aluminium powder to measure part proportioning（200 mesh, Al2O3≥60%）5 parts, magnesia（320 mesh, MgO >=95%）2 parts, 1 part of yellow starch gum, 2 parts of clay,
Additive carboxymethyl cellulose 0.5%, sodium tripolyphosphate 0.15%.Apply man-hour requirement and add water 10% or so, be adjusted to dilute denseness and be easy to apply
Work.
The advantage of the invention is that method for repairing and mending is simple, refractory consumption is reduced, due to need not be complete by the brick body of damage
It is complete to remove, the impurity on brick surface only need to be removed, one layer of splits is then directly pasted on top layer, when substantially reducing repairing blowing out
Between, save the use of material for repairing；Simultaneously because the lining brick damaged reduces the generation for abandoning useless brick admittedly, more without removing again
Beneficial to environmental protection, there are good economic implications and social effect.
Embodiment
More detailed explanation is done to the inventive method with reference to Repair Examples.
By taking 100 tons of ladles of Hebei Qian'an Jiujiang wire rod Co., Ltd as an example, after 120 stoves, its containment wall site tissue damage compared with
Weight, it is impossible to maintain the lasting use in later stage, it is necessary to repair.Using the synthesis repairing method of the present invention during repairing：
The first step, according to containment wall attack sites, it is determined that needing the working lining brick repaired to have 12 layers, working lining brick is aluminium-magnesia carbon brick；
Second step, it would be desirable to which the residual steel waste residue and metamorphic layer on the working lining brick surface of repairing are disposed, convenient follow-up repairing；
3rd step, is excavated undermost working lining brick using instruments such as pneumatic picks, notes that upper strata brick body can not be destroyed when excavating；
4th step, the neutral position that the new brick insertion of the aluminium-magnesia carbon brick of same material is dug out, embedded new brick should be more original than upper strata
Working lining brick protrudes 40 ~ 60mm（Depth as do not removed brick originally is 150mm, then embedded brick should be 190mm-210mm）, with
Play a part of holding up and subsidize above with brick；
5th step, with the thick new bricks of aluminium-magnesia carbon brick of 40 ~ 60mm, is close to working lining brick from bottom to top successively on the new brick of protrusion
Subsidized, until 12 layers of working lining brick for needing to repair are completely covered, reach the purpose that working lining is thickened with splits, it is most lower
The protrusion brick of layer has held up the splits for the 40 ~ 60mm thickness subsidized above well, it is to avoid coming off for supplement brick.
To ensure the secure fit between supplement brick and former working lining brick, it is to avoid coming off for supplement brick, new brick is used subsidizing
Need to use magnalium chamotte bonding agent between working lining brick, raw materials used weight is：Aluminium powder（200 mesh, Al2O3≥
60%）5 parts, magnesia（320 mesh, MgO >=95%）2 parts, 1 part of yellow starch gum, 2 parts of clay, additive carboxymethyl cellulose 0.5%, trimerization
Sodium phosphate 0.15%.Also need to add water during construction and 10% or so be adjusted to dilute denseness and be easy to construction.
It is suitable that this ladle reuses the life-span after subsidizing use of reaching the standard grade again, with the normal ladles for all removing bricks, does not have
The phenomenon of bag age downslide is occurred, is contrasted using such a method 12 layer indentured brick to be repaired with all dismountings that subsidize, Ke Yijie
About 7 tons of aluminium-magnesia carbon brick is saved, the useless brick that should be removed originally is made full use of, it is to avoid waste of material, environmental hazard is reduced, again
Add economic benefit.
