Abstract
The present invention relates to a kind of methods of Rapid-Repair converter lining, include the following steps：1), patching material prepares：Prepare pig and refractory brick；2), after the completion of converter tapping, part clinker is poured out；3), refractory brick is packed into steel bucket, converter face is put by steel bucket, makes the 80% of refractory brick covering converter lining eroded section；4), shaking converter makes refractory brick be laid on the large face of converter being etched；5) pig, is added on the upper layer of refractory brick；6), shaking converter keeps pig tiling uniform, ensures that converter lining is etched part and is completely covered；7) after, refractory brick and pig are filled in converter attack sites, the static 10min of furnace body makes refractory brick sintering adhesive bonding on converter lining using the high temperature furnace slag in converter, after 10min can grate steel-making, repair complete.Adaptation to local conditions of the present invention, gathers materials on the spot, and solves the problems, such as that the large face of converter repairing time is longer；Filling time foreshortens to 10min from original 70min.Have many advantages, such as simple, convenient and refuse reclamation, economizes on resources, reduces cost, environmental protection.
Description
Technical field
The invention belongs to converters to repair technical field, more particularly to a kind of method of Rapid-Repair converter lining.
Background technology
Can all occur the problem of liner erosion, especially stove in convertor steelmaking process and use as a servant the later stage, converter is close to master control room one
Wing furnace serves as a contrast (big face) and corrodes serious, and the type of furnace is caused to deform, poor and there are problems that security risk so as to cause metallurgical effect, because
This each factory is all made of the stabilization for the technical maintenance type of furnace for repairing big face.Currently, big face repairing uses material for oil-sand, resistant to corrosion stove
Number can reach 10-15 stoves, but there is repairing time length (about 70min), the problem for causing converter operating rate low.
It is studied for large face of converter repairing time longer problem, using the existing material in our factory, has invented one
The novel fettling method of kind solves the problems, such as that the large face of converter repairing time is longer.
Invention content
The present invention provides a kind of simple, convenient, easy side to solve technical problem present in known technology
The method that method solves the problems, such as large face of converter repairing time longer Rapid-Repair converter lining.
The present invention is adopted the technical scheme that solve technical problem present in known technology：
A kind of method of Rapid-Repair converter lining, it is characterised in that：Include the following steps：
1) patching material prepares：Prepare pig and refractory brick；
2), after the completion of converter tapping, part clinker is poured out；
3), refractory brick is packed into steel bucket, converter face is put by steel bucket, refractory brick is made to cover converter lining eroded section
80%；
4), shaking converter makes refractory brick be laid on the large face of converter being etched；
5) pig, is added on the upper layer of refractory brick；
6), shaking converter keeps pig tiling uniform, ensures that converter lining is etched part and is completely covered；
7) after, refractory brick and pig are filled in converter attack sites, the static 10min of furnace body utilizes the high temperature in converter
Clinker makes refractory brick sintering adhesive bonding on converter lining, after 10min can grate steel-making, repair complete.
The invention has the advantages and positive effects that：Adaptation to local conditions of the present invention is gathered materials on the spot discarded refractory brick and life
Iron block carries out fettling use, solves the problems, such as that the large face of converter repairing time is longer；Filling time foreshortens to from original 70min
10min.Resistant to corrosion stove number uses oil-sand fettling effect suitable with original；The present invention also has simple, convenient and waste sharp again
With, economize on resources, reduce cost, environmental protection the advantages that.
Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and it is described in detail
It is as follows：
A kind of method of Rapid-Repair converter lining, includes the following steps：
1) patching material prepares：Prepare pig and refractory brick；
2), after the completion of converter tapping, part clinker is poured out；
3), refractory brick is packed into steel bucket, converter face is put by steel bucket, refractory brick is made to cover converter lining eroded section
80%；
4), shaking converter makes refractory brick be laid on the large face of converter being etched；
5) pig, is added on the upper layer of refractory brick；
6), shaking converter keeps pig tiling uniform, ensures that converter lining is etched part and is completely covered；
7) after, refractory brick and pig are filled in converter attack sites, the static 10min of furnace body utilizes the high temperature in converter
Clinker makes refractory brick sintering adhesive bonding on converter lining, after 10min can grate steel-making, repair complete.
Adaptation to local conditions of the present invention gathers materials on the spot discarded refractory brick and pig carrying out fettling use, it is big to solve converter
Repair time longer problem in face；Filling time foreshortens to 10min from original 70min.Resistant to corrosion stove number with mended originally with oil-sand
Stove effect is suitable；The present invention also have simple, convenient and refuse reclamation, economize on resources, reduce cost, environmental protection etc. it is excellent
Point.
The above is only the preferred embodiments of the present invention, and is not intended to limit the present invention in any form,
Every any simple modification made to the above embodiment according to the technical essence of the invention, equivalent variations and modification, belong to
In the range of technical solution of the present invention.
